Description

  The present invention relates to a medical image diagnostic apparatus, a medical image processing apparatus, and a medical image processing system, and more particularly to a technique for specifying an imaging region of a medical image.

  Medical diagnostic imaging apparatuses such as an X-ray CT (Computed Tomography) apparatus and an MRI (Magnetic Resonance Imaging) apparatus have been widely used in various medical institutions.

  In recent years, for example, a multi-slice type X-ray CT apparatus (an X-ray CT apparatus having an X-ray detector in which a plurality of detection elements are two-dimensionally arranged) has been introduced, and the speed of scanning has been advanced. (For example, see Patent Document 1 below). In addition, the speed of reconstruction processing for reconstructing an image from data collected by scanning is also being promoted (see, for example, Patent Document 2).

  Along with such development, scanning of a plurality of imaging regions (body, head, chest, abdomen, feet, chest & abdomen, etc.) of a subject can be performed by a series of scans (helical scans). Patent Document 3 discloses an invention in which a plurality of medical images are grouped based on an imaging region, examination date and time, and examination type.

  FIG. 23 shows an examination processing procedure and data flow by a medical image processing system including a conventional medical image diagnostic apparatus (X-ray CT apparatus). This figure shows a case where a scan position and a scan condition are set using a scanogram (a plane transmission image from a certain direction).

  First, the subject is placed on the bed and the scan start position is aligned with the subject (S1000), and a scanogram of the subject is acquired (S1002). The examiner determines the scan range (start position or end position of the scan), tube current value of the X-ray tube, tube voltage value, reconstruction function, imaging region based on the obtained scanogram and information on the alignment result. And the like (referred to as scanning conditions) are set (S1003). In addition, regarding the imaging | photography site | part, generally one site | part is selectively designated (for example, refer patent document 4).

  Next, based on the set scan conditions, the subject is X-ray scanned to collect data (S1004), and a tomographic image is reconstructed based on the collected data (S1005). The collected data and the image data of the reconstructed tomographic image are sent to the filing system 1000. The above processing is executed by the X-ray CT apparatus.

  The filing system 1000 is a system that stores and manages collected data and image data files of tomographic images, and includes, for example, a PACS (Picture Archiving and Communication System).

  When a predetermined file operation is performed (S1006), the filing system 1000, for example, transmits image data of tomographic images to another apparatus such as a viewer for interpretation, or records image data on a medium (information recording medium). Execute processing. In addition, a file can be deleted or edited by a predetermined file operation.

  The conventional devices and systems as described above have the following problems. First, in the conventional configuration, only one imaging part can be specified when performing a scan. Therefore, even when scanning a plurality of parts by a series of scans, only one of the plurality of parts is specified. I couldn't.

  Therefore, when observing the reconstructed image, there is a possibility that the part indicated by the displayed image may be different from the imaging part specified for the image, and thus the part of the display image may not be specified accurately. Arise. In addition, when storing collected data or image data of a reconstructed image, image data corresponding to a designated part and image data corresponding to a part different from the specified part are mixed. In addition, there may be a problem that the imaging region is not clearly specified.

  Although it is possible to specify “whole body”, “chest & abdomen”, etc. as the imaging part, the single part is specified because the part of each reconstructed image based on a series of scans cannot be specified clearly It is the same as the case of doing.

  On the other hand, if the invention described in Patent Document 3 is applied, the part of the reconstructed image can be specified, but it is difficult to specify the body part corresponding to the data collected in the scan.

  In addition, the invention described in Patent Document 3 includes boundary information for grouping a plurality of tomographic images for each part based on the position information of a bed recorded in supplementary information of DICOM (Digital Imaging and Communications in Medicine). It works as you ask. However, there are cases where it is difficult to clearly specify the boundary between these parts, for example, when distinguishing between a tomographic image corresponding to the chest and a tomographic image corresponding to the abdomen.

  Furthermore, Patent Document 3 discloses a method for specifying an imaging region based on the number of connected regions in a pixel distribution histogram of an image, but it is also adjacent to each other like a chest and an abdomen, and For parts having the same number of connected regions, those parts cannot be distinguished. In addition, although it is described that the imaging region is specified by the maximum value, range, area, etc. in the pixel histogram, it is considered that there is a region that cannot be clearly specified in consideration of individual differences of subjects.

  The present invention has been made to solve the above-described problems, and even when images of a plurality of parts of a subject are photographed at a time, the photographing part of each image can be specified. An object of the present invention is to provide a medical image diagnostic apparatus, a medical image processing apparatus, and a medical image processing system.

The front-rear direction is the body axis direction of the subject P on the top 21.

[About the information specification section]
In addition, the bed apparatus 20 is provided with an information designating unit 23 as shown in FIG. The information designating unit 23 is used to designate a range of a desired part of the subject P placed on the top plate 21 and the name of the part, and corresponds to an example of “designating means” of the present invention. Is.

  Here, the part of the subject P means a body part of the subject P such as the head, chest, abdomen, pelvis, and foot. The range of the part means the range of the body of the subject P corresponding to the part.

  As shown in FIG. 4, the information specifying unit 23 includes a rail 23 </ b> A disposed on the top 21 along the longitudinal direction of the top 21 (the body axis direction of the subject P), and the subject on the rail 23 </ b> A. A plurality of body part designating parts 23a, 23b, 23c, and 23d provided to be movable along the body axis direction of P. These body part designating parts 23a, 23b, 23c, and 23d are in this order from the head direction of the subject P toward the foot part (from the side closer to the gantry 30 of the top plate 21 toward the far side). Has been placed. It should be noted that the number of installed body part designating parts is not limited to four, and an arbitrary number of body part designating parts can be provided.

  The information designating unit 23 acts to detect the positions of the body part designating units 23a to 23d on the rail 23A (position in the longitudinal direction of the top plate 21), for example, position detecting means (not shown) such as a potentiometer. ) Is provided.

  Arbitrary structures can be adopted as a connection mode between the rail 23A and the body part designating units 23a to 23d. For example, while using the rail 23A which has the convex part which protruded upwards along the longitudinal direction of the top plate 21, the recessed part engaged with this convex part is provided in each body part designation | designated part 23a-23d, and each body part designation | designated part 23a-23d can be configured to slide on the rail 23A.

  In FIG. 5, the detailed structure of the body part designation | designated parts 23b and 23c is shown. Here, since each body part designation | designated part 23a, 23d is equipped with the same structure altogether, only the body part designation | designated part 23b is demonstrated.

  When viewed from above, the body part designating unit 23b is directed in the short direction of the top plate 21 (the direction perpendicular to the body axis direction of the subject P) so as to indicate the direction of the subject P as shown in FIG. It has an arrow shape.

  The body part designating unit 23b includes a direction presenting unit 231 that presents a triangular image indicating the longitudinal direction of the top board 21, and a button for changing the direction indicated by the triangular image presented by the direction presenting unit 231. And a direction changing operation unit 232 including a dial and the like. The direction changing unit 231 and the direction changing operation unit 232 are for specifying the range of the top 21 along the body axis direction of the subject P, and correspond to an example of the “top range specifying means” of the present invention. Is.

  The direction presentation unit 231 is configured by a flat panel display such as an LCD (Liquid Crystal Display) that displays a triangular image, for example. Moreover, it is also possible to employ the direction presentation unit 231 configured to include a mechanism for switching the presentation content (the direction of the triangular image) in response to an operation on the direction change operation unit 232. In addition, the direction presentation unit 231 and the direction change operation unit 232 can be integrally configured by using a touch panel type LCD or the like.

  As shown in FIG. 5 and FIG. 6A, when the direction changing operation unit 232 is operated when a triangular image indicating the head direction of the subject P is presented on the direction presentation unit 231, the direction presentation unit 231 is operated. Operates so as to present a triangular image indicating the foot direction of the subject P as shown in FIG. Conversely, when the direction changing operation unit 232 is operated while the triangular image indicating the foot direction of the subject P is presented on the direction presentation unit 231, the direction presentation unit 231 displays the head direction of the subject P. Operates to present a triangular image of pointing.

  Further, the body part designating part 23b includes a part name presentation part 233 for presenting the name of the body part, and a part comprising a button or a dial for changing the name of the body part presented by the part name presentation part 233. A name change operation unit 234 is provided. The part name changing unit 233 and the part name changing operation part 234 are for specifying the name of the body part corresponding to the range of the top 21 specified by the direction changing part 231 and the direction changing operation part 232. This corresponds to an example of “name designation means”.

  The part name presentation unit 233 is configured by, for example, a flat panel display such as an LCD that displays characters (character strings) indicating the names of body parts. It is also possible to employ a part name presentation unit 233 configured to include a mechanism for switching the presentation content (name of the body part) in response to an operation on the part name change operation unit 234. Further, by using a touch panel type LCD or the like, the part name presentation unit 233 and the part name change operation unit 234 can be integrally configured. Similarly, the direction change unit 231, the direction change operation unit 232, the part name presentation unit 233, and the part name change operation unit 234 can be integrally configured.

  Each time the part name changing operation unit 234 is operated, the names of the body parts presented in the part name presentation unit 233 are sequentially switched (cyclically) as shown in FIG. That is, when the part name change operation unit 234 is operated while the character “chest” is presented as shown in FIG. 7A, the part name presentation unit 233 displays the character “ Operates to present "belly". When the part name change operation unit 234 is operated when the character “belly” is presented as shown in FIG. 7B, the part name presentation unit 233 displays the character string as shown in FIG. 7C. Operates to present a “pelvis”. When the part name change operation unit 234 is operated while the character string “pelvis” is presented as shown in FIG. 7C, the part name presentation unit 233 displays the characters as shown in FIG. 7D. Operates to present a "foot". When the part name changing operation unit 234 is operated while the character “foot” is presented as shown in FIG. 7D, the part name presenting unit 233 displays the character “ It works to present a “head”. When the part name changing operation unit 234 is operated when the character “head” is presented as shown in FIG. 7E, the part name presenting part 233 displays the character string as shown in FIG. Operates to present “chest”.

  For example, when a certain body part designating part is not used, the part name presenting part 233 may present a character string such as “no designation” or a symbol such as “−”. When such a character string or symbol is presented, it is not necessary to perform the detection of the designated position on the top plate 21 by the body part designating part (the operation of the position detecting means described above).

  When the designation of the range of the part of the subject P and the designation of the name of the part are made by the body part designating parts 23a to 23d, the information designating part 23 is designated by the position detecting means described above. The position (coordinate value) of 23d on the rail 23A is detected. The detection position is, for example, the position of the tip of each of the body parts designating parts 23a to 23d having an arrow shape.

  FIG. 5 shows an example of how the region P and the region name of the subject P specified by the information specifying unit 23 are specified. In the body part designating part 23b of the figure, a triangular image indicating the head direction of the subject P is presented on the direction presenting part 231, and the character “chest” is presented on the part name presenting part 233. Further, in the body part designating unit 23c in the same figure, a triangle image indicating the head direction of the subject P is also presented on the direction presenting part 231, and the character “abdomen” is presented on the part name presenting part 233. Has been.

  Although illustration is omitted, the direction presenting unit 231 of the body part designating units 23a and 23d also presents a triangle image indicating the head direction of the subject P on the direction presenting unit 231. It is assumed that the character “head” is presented in the part name presenting part 233 of the part 23a, and the character string “pelvis” is presented in the part name presenting part 233 of the body part designating part 23d.

  In this case, it means that the range of the part of the subject P and the part name are designated as follows: (1) Range A in the head direction of the subject P from the body part designating part 23a (not shown) ) Is designated as the range of the “head” of the subject P, and this range A is acquired as the range in the head direction of the subject P rather than the position (coordinate value) of the body part designating part 23a; 2) A range B between the body part designating part 23a and the body part designating part 23b is designated as the “chest” range of the subject P, and this range B is the position (coordinate value) of the body part designating part 23a. And the position (coordinate value) of the body part designating part 23b; (3) The range C between the body part designating part 23b and the body part designating part 23c is the "abdominal part of the subject P" The range C is the position (coordinates) of the body part designating part 23b. ) And the position (coordinate value) of the body part designating part 23c; (4) the range D between the body part designating part 23c and the body part designating part 23d is “ The range D is acquired as a range between the position (coordinate value) of the body part specifying unit 23c and the position (coordinate value) of the body part specifying unit 23d.

  The same applies to the case where the triangular image presented by the direction presentation unit 231 of each of the body part designating units 23a to 23d indicates the foot direction of the subject P.

  The information specifying unit 23 transmits the result of specifying the region range (the range indicated by the coordinate values) and the region name of the subject P as described above to the console 10. The console 10 is configured to transmit the received designation result to the gantry 30. When the couch device 20 and the gantry 30 are connected so as to be directly communicable, the information designating unit 23 may transmit the designation result to the gantry 30 as well.

[Gantry]
The gantry 30 incorporates a rotatable support 30a as shown in FIG. An X-ray tube 30b and an X-ray detector 30c are supported on the support 30a. The X-ray tube 30b generates X-rays based on a predetermined tube voltage and tube current applied by the high voltage generator 30d, and is applied to the subject P located in the opening 30A (see FIG. 2) of the gantry 30. X-ray fan beam or cone beam is irradiated. The X-ray detector 30c is supported at a position facing the X-ray tube 30b, and has a configuration in which a plurality of X-ray detection elements that detect the dose of the X-ray beam that has passed through the subject P are arranged in an array. is doing.

  The support 30a is rotated around the opening 30A by the support driving unit 30e. The X-ray tube 30b and the X-ray detector 30c are rotated along with the rotation of the support 30a to scan the subject P, and thereby the X-ray dose of the X-ray beam transmitted through the subject P from various directions. It comes to detect. The transmitted X-ray dose data (detection signal) detected by the X-ray detector 30 c is sent to the data collection unit 31.

  The data collection unit 31 includes a device called a so-called DAS (Data Acquisition System), and has data collection elements arranged in an array like the X-ray detection elements of the X-ray detector 30c. The X-ray detector 30c operates so as to collect transmitted X-ray dose data.

  The data collection unit 31 performs amplification processing, A / D conversion processing, and the like on the data reflecting the internal form of the subject P collected in this way and transmits the data to the console 10. At this time, the data collection unit 31 adds information indicating the scan position of the subject P by the X-ray tube 30b and the X-ray detector 30c (represented by a z-coordinate value described later) to the detection signal. Then it is transmitted to the console. Here, the information indicating the scan position is information indicating the result of the scan alignment performed in step S1001 in FIG. 23. For example, a storage area for adding information defined in DICOM (referred to as a DICOM tag). It is stored in a predetermined storage area. The data collection unit 31 (gantry 30) corresponds to an example of the “collection unit” of the present invention.

  The support driving unit 30e not only rotates the support 30a as described above, but also operates to tilt (tilt) the support 30a with respect to the subject P. In addition, it is also possible to provide separately the structure for rotating the support body 30a, and the structure for tilting the support body 30e.

  The gantry 30 is further provided with an information display unit 32. The information display unit 32 displays the range of the part of the subject P and the name of the part (part name) specified using the information specifying unit 23 of the bed apparatus 20 or the user interface 15 (described later) of the console 10. This corresponds to an example of the “designated information display means” of the present invention. This information display part 32 is comprised by arbitrary display devices, such as LCD, for example. Moreover, the information display part 32 is arrange | positioned at the housing | casing side surface of the bed apparatus 20 side of the gantry 30, for example.

  An example of the display mode of the part range and the part name by the information display unit 32 is shown in FIG. As shown in the figure, the information display unit 32 includes a “range start position” column indicating the start position of the (X-ray) scan range corresponding to each specified range as the specified range of the site of the subject P. A “range end position” column indicating the end position of the scan range is provided. In these columns, scan ranges (start position, end) corresponding to each designated range based on coordinate values (z coordinate values) set in advance in the body axis direction of the subject P (longitudinal direction of the top plate 21; z direction). Position) is displayed. Further, the information display section 32 is provided with a “part name” column indicating the name of the part for each designated range.

  In the display mode shown in FIG. 8, “chest”, “abdomen”, and “pelvis” are displayed as the result of specifying the site name of the subject P (in the column “site name”). This means that the chest, abdomen, and pelvis are designated as examination sites using the information designation unit 23 (or the user interface 15).

  Further, in the information display unit 32 of FIG. 8, for the part name “chest”, the z coordinate value “100” designated at the start position of the scan range and the z coordinate value “120” designated at the end position are displayed. Are displayed ("Range start position" field, "Range end position" field). The fact that this scan range is a scan range corresponding to “chest” indicates that “chest” is presented in the part name presenting part 233 of the body part designating part 23 b and the head direction of the subject P is presented in the direction presenting part 231. It is specified by the presentation of a triangular image indicating (the direction of the body part designating part 23a).

  Further, the z coordinate value “100” of the start position of the scan range of “chest” is the coordinate value corresponding to the position of the body part designating unit 23a shown in FIG. Is obtained by detecting. Similarly, the z-coordinate value “125” of the end position of the scan range is obtained by detecting the coordinate value corresponding to the position of the body part designating unit 23b shown in FIGS. 4 and 5 by the position detection unit. Is.

  The display processing of the part names “abdomen”, “pelvis”, and the start position and end position of the scan range is similarly executed. Note that the z coordinate value shown in the setting information of the scan range shown in FIG. 8 is the coordinate value at the same z coordinate as the scan position of the subject P obtained from the data collection unit 31.

  Note that the control of the above-described display processing by the information display unit 32 is performed by, for example, the control unit 11 of the console 10. In addition, when the designation result is directly transmitted from the couch device 20 to the gantry 30 as described above, a microprocessor such as a CPU (Central Processing Unit) that performs display control by the information display unit 32 is used, for example, the gantry 30. You may make it provide in.

  Furthermore, the image data classification processing unit 143 classifies the image data of a plurality of medical images for each body part based on the body part specified for the image data of each medical image.

  Here, an example of the processing contents by the image data classification processing unit 143 when the designation result shown in FIG. 8 is used will be described. The image data classification processing unit 143 specifies the range of a part including the scan position (z coordinate value) for each of the image data (n = 1 to N) of N medical images. As a result, each scan position of the image data n = 1 to n1 is included in 100 ≦ z ≦ 120, and each scan position of the image data n = n1 + 1 to n1 + n2 is included in 120.1 ≦ z ≦ 150. Assume that the scan positions of image data n = n2 + 1 to n2 + n3 are included in 150.1 ≦ z ≦ 175 (N = n1 + n2 + n3).

  In this case, the image data classification processing unit 143 refers to the designation result shown in FIG. 8 and the image data n = 1 to n1 of n1 medical images obtained by photographing “chest” (within the range designated for the chest). An image having slice positions), and n2 medical image data n = n1 + 1 to n1 + n2 are obtained by photographing the “abdomen” (an image having a slice position in a range designated in the abdomen), and n3 medical images The image data n = n2 + 1 to n2 + n3 are obtained by photographing the “pelvis” (an image having a slice position in a range designated by the pelvis).

  Such classification results are stored, for example, in a table format. The image data classified into the same group may be associated with the same identification information (identification information indicating the classification result).

[Operation]
The operation of the medical image processing system 1 having the above configuration will be described. The flowcharts shown in FIGS. 10 to 13 represent an example of the operation of the medical image processing system 1.

  Here, the flowchart shown in FIG. 10 represents an example of the operation of the medical image processing system 1 in the case of designating the region range and region name of the subject P using the information designating unit 23 of the bed apparatus 20. Further, the flowchart shown in FIG. 11 represents an example of the operation of the medical image processing system 1 in the case where the range of the region of the subject P and the region name are designated using the user interface 15 of the console 10. 12 is a flowchart of the medical image processing system 1 in the case where the range of the part of the subject P and the part name are specified using both the information specifying unit 23 of the bed apparatus 20 and the user interface 15 of the console 10. An example of the operation is shown. In the flowchart shown in FIG. 13, the range and part name of the part of the subject P are attached to the medical image (image data) of the subject P acquired in advance using the user interface 15 of the console 10. An example of the operation of the medical image processing system 1 in the case of designating is shown.

[First operation example: FIG. 10]
First, the operation of the medical image processing system 1 in the case where a region range and a region name of the subject P are specified using the information specifying unit 23 of the bed apparatus 20 will be described with reference to FIG.

  First, the subject P is placed on the top plate 21 of the bed apparatus 20. Then, by operating the information specifying unit 23 in the manner described above, the range of the part and the part name of the subject P are specified (S1). This designation result is stored, for example, in a storage device (memory, hard disk drive or the like; not shown) of the bed apparatus 20 or a storage device (described above) such as a memory or hard disk drive of the control unit 11 of the console 10.

  Further, the range and part name information of the subject P specified in step S1 is transmitted to the gantry 30 (directly from the bed apparatus 20 or via the console 10) and displayed on the information display unit 32. (S2). The user can confirm the designated content by referring to the information displayed on the information display unit 32, and can change the designated content as necessary.

  When the designation of information is completed, a scanogram of the subject P (at least the range of all designated parts) is acquired (S3). For this purpose, first, the user inputs an X-ray scan start request for acquiring a scanogram using the user interface 15 of the console 10. A signal indicating the start request is transmitted to the bed apparatus 20 and the gantry 30. In response to this signal, the bed apparatus 20 and the gantry 30 execute an X-ray scan for acquiring a scanogram of the subject P. In this X-ray scan, the X-ray tube 30b and the X-ray detector 30c of the gantry 30 are placed at predetermined positions (for example, the X-ray tube 30b is placed at the front position of the subject P and the X-ray detector 30c is placed at the back face position. In this state, the top plate 21 is moved in the body axis direction of the subject P. In this process, data detected by the X-ray detector 20 is collected by the data collecting unit 31 and sent to the console 10. The console 10 (for example, a microprocessor) generates image data of a scanogram of the subject P based on the data collected by the data collection unit 31 by executing a predetermined computer program.

  The control unit 11 causes the display unit 16 to display the acquired scano image. The user operates the information specifying operation unit 17 to set scan conditions such as a scan range (X-ray scan start position and end position), a tube current value and a tube voltage value of the X-ray tube 30b, and a slice thickness ( S4). The setting content of the scan condition is transmitted to the bed apparatus 20 and the gantry 30.

  The bed apparatus 20 and the gantry 30 execute an X-ray scan (for example, a helical scan) of the subject P based on the set scan conditions (S5). The pure raw data collected by the data collecting unit 31 during the X-ray scanning process is sent to the console 10 together with the scan position information and the range and part name designation results of the subject P designated in step S1. Sent. In step S 2, when the designation result is transmitted to the gantry 30 via the console 10, only pure raw data and scan position information may be transmitted to the console 10.

  The preprocessing unit 12 of the console 10 generates raw data (projection data) by performing predetermined preprocessing on the pure raw data (S6). The reconstruction unit 13 performs the following image reconstruction process.

  First, the reconstruction function selection unit 132 selects one of a plurality of reconstruction functions stored in the reconstruction function storage unit 133 based on the designation result in step S1 (S7). Thereby, for each slice position, a reconstruction function corresponding to the body part to which the slice position belongs is selected.

  Based on the raw data generated by the preprocessing unit 12, the image reconstruction processing unit 131 generates tomographic image data using the selected reconstruction function for each slice position (S8). Thereby, image data of a tomographic image of the subject P at each of a plurality of slice positions is obtained.

  Subsequently, the body part identification processing unit 141 of the information processing unit 14 is designated based on the scan position when the pure raw data based on the image data of each tomographic image is collected by the data collection unit 31. The range of one part is selected from the range of the part of the subject P, and the body part indicated by the image data of the tomographic image is specified (S9). And the information provision process part 142 provides the body part information which shows the specified body part with respect to the image data of each tomographic image (S10).

  Further, the image data classification processing unit 143 of the information processing unit 14 classifies the image data of the plurality of tomographic images obtained by the reconstruction unit 13 for each body part based on the designation result in step S1 (S11).

  Based on the classification result, the control unit 11 classifies the raw data that is the basis of the image data of the tomographic image (S12). That is, for the image data of each tomographic image, the image data of the tomographic image is associated with the raw data that is the basis of the image data of the tomographic image.

  The control unit 11 then converts the tomographic image data and / or raw data for each classified body part based on the classification results in steps S11 and S12 (for example, in response to a request from the workstations 40A and 40B). To the communication unit 19. The communication unit 19 transmits the image data and / or raw data of the tomographic image received from the control unit 11 to the workstations 40A and 40B for each body part (S13).

  More specifically, for example, the control unit 11 transmits tomographic image workstation 40A image data and / or raw data of a tomographic image in which the region name is “chest”, and the region name is “abdomen”. The image data and / or raw data of the tomographic image determined is transmitted to the abdominal image workstation 40B. At this time, the workstations 40A and 40B serving as transmission destinations are specified by the above-described identification information. The body part information given by the information giving processing unit 142 may be transmitted to the workstations 40A and 40B together with the image data of the tomographic image.

  In addition, the control unit 11 (for example, in response to a request from the user) sets the image data and / or raw data of the tomographic image for each classified body part based on the classification results in steps S11 and S12. Send to 18. The information recording unit 18 records the image data and / or raw data of the tomographic image received from the control unit 11 on the medium 18a for each body part (S14). Thereby, image data and raw data of a tomographic image for each part of the subject P such as the chest and abdomen can be recorded on the medium 18a.

  Here, it is desirable to record the body part information provided by the information addition processing unit 142 together with the image data of the tomographic image or the like on the medium 18a. Accordingly, when reading out the image data of the tomographic image recorded on the medium 18a, the user can easily grasp which body part the data relates to by reading out and displaying the body part information. can do.

  The control unit 11 transmits image data and / or raw data of tomographic images based on the classification results in steps S11 and S12 to a filing system (not shown) such as PACS as shown in FIG. Can be configured.

  In that case, the user of the filing system, for example, organizes the tomographic images (data management hierarchy “inspection”, “series”, “image” etc. in DICOM), etc.), other devices (eg, workstations 40A, 40B, etc. Various file operations such as data transfer to a computer or the like and data storage (backup) on various media can be performed.

[Second Example of Operation: FIG. 11]
Next, the operation of the medical image processing system 1 in the case where the range of the part of the subject P and the part name are designated using the user interface 15 of the console 10 will be described with reference to FIG. Note that detailed description of the same processing as in the first operation example will be omitted.

  First, the subject P is placed on the top plate 21 of the bed apparatus 20, and a scanogram of the subject P is acquired in the same manner as in the first operation example (S21).

  The control unit 11 displays the acquired scano image on the display unit 16 (S22). This scanogram is displayed on, for example, the image display unit 510 in the information designation screen 500 shown in FIG. For example, the user designates the range of the part of the subject P and the part name in the manner described below (S23). This designation result is stored in a storage device such as a memory of the control unit 11 of the console 10 or a hard disk drive, for example.

  The following processing related to the information designation screen 500 is executed by the control unit 11.

  An example of the image display unit 510 of the information designation screen 500 is shown in FIG. The image display unit 510 is provided with an information specifying unit 512 similar to the information specifying unit 23 of the bed apparatus 20. The information specifying unit 512 includes a plurality of body part specifying units 512a, 512b, and 512c.

  Each body part designation | designated part 512a, 512b, 512c can be moved on the scale image 511 displayed along the longitudinal direction of the top plate 21, for example by drag operation using the mouse | mouth of the user interface 15. FIG. Thereby, the user can determine the boundary position of the range of the site | part to designate.

  Each body part designating part 512a, 512b, 512c is provided with a direction presenting part and a part name presenting part similar to the body part designating part 23a of the information designating part 23 and the like.

  A triangular image indicating the longitudinal direction of the top plate 21 (the body axis direction of the subject P) is presented on the direction presentation unit. The user can switch and present a triangular image indicating the head direction of the subject P and a triangular image indicating the foot direction by clicking the direction presenting portion with a mouse, for example. .

  In addition, the part name presenting part presents the name of the body part, like the body part designating part 23a. For example, when the user clicks on a part name presentation unit, a pull-down menu listing options of names of body parts is displayed. When the user operates the mouse or the like to select the name of a desired body part, the name (part name) of the selected body part is displayed on the part name presentation unit. As described above, the specification of the range and part name of the subject P using the scanogram displayed on the image display unit 510 is completed.

  Furthermore, the user sets scan conditions by operating soft keys such as various buttons provided on the information designation screen 500 (S24). The setting content of the scan condition is transmitted to the bed apparatus 20 and the gantry 30.

  Note that either the designation of the range of the part of the subject P or the setting of the scan condition may be performed first. In addition, the specification of the range of the part of the subject P and the setting of the scan condition can be performed in parallel.

  The range and part name information of the subject P specified in step S23 is transmitted from the console 10 to the gantry 30 and displayed on the information display unit 32 (S25). In the operation example, the process of step S25 can be omitted.

  The bed apparatus 20 and the gantry 30 execute an X-ray scan of the subject P based on the set scan conditions (S26). Pure raw data collected by the data collection unit 31 in the course of this X-ray scanning is transmitted to the console 10 together with information on the scan position.

  The preprocessing unit 12 of the console 10 generates raw data by performing predetermined preprocessing on the pure raw data (S27).

  The reconstruction function selection unit 132 selects one of the plurality of reconstruction functions stored in the reconstruction function storage unit 133 based on the designation result in step S23 (S28). The image reconstruction processing unit 131 generates tomographic image data using the selected reconstruction function for each slice position based on the raw data generated by the preprocessing unit 12 (S29).

  Subsequently, the body part identification processing unit 141 of the information processing unit 14 is designated based on the scan position when the pure raw data based on the image data of each tomographic image is collected by the data collection unit 31. The range of one part is selected from the range of the part of the subject P, and the body part indicated by the image data of the tomographic image is specified (S30). And the information provision process part 142 provides the body part information which shows the specified body part with respect to the image data of each tomographic image (S31).

  Further, the image data classification processing unit 143 of the information processing unit 14 classifies the image data of the plurality of tomographic images obtained by the reconstruction unit 13 for each body part based on the designation result in step S23 (S32).

  Based on the classification result, the control unit 11 classifies the raw data that is the basis of the image data of the tomographic image (S33).

  Then, the control unit 11 sends the image data and / or raw data of the tomographic image to the communication unit 19 based on the classification results in steps S32 and S33. The communication unit 19 transmits the image data and / or raw data of the tomographic image received from the control unit 11 to the workstations 40A and 40B for each classified body part (S34).

  Further, the control unit 11 sends the image data and / or raw data of the tomographic image to the information recording unit 18 for each classified body part based on the classification results in steps S32 and S33. The information recording unit 18 records the image data and / or raw data of the tomographic image received from the control unit 11 on the medium 18a for each body part (S35). Here, it is desirable to record the body part information provided by the information addition processing unit 142 together with the image data of the tomographic image or the like on the medium 18a.

  Note that, similarly to the first operation example, the control unit 11 performs image data and / or raw data of tomographic images based on the classification results in steps S32 and S33 for a filing system such as PACS as shown in FIG. Can be configured to be transmitted for each body part. The user of the filing system can perform various file operations as described above.

  Further, the range information and the site name information of the designated subject P are transmitted to the gantry 30 and displayed on the information display unit 32 (S42).

  When the designation of information by the information designation unit 23 is completed, a scanogram of the subject P is acquired (S43). The control unit 11 causes the display unit 16 to display the acquired scano image (S44). This scanogram is displayed on the image display unit 510 in the information designation screen 500 shown in FIGS. 14 and 15 as in the second operation example.

  In addition, the control unit 11 reflects the region range and region name information of the subject P specified using the information specifying unit 23 in step 41 on the body part specifying units 512a, 512b, and 512c of the information specifying screen 500. (S45). That is, the designation result in step S41 is displayed on the body part designation units 512a, 512b, and 512c.

  For example, the same image as the triangular image presented in the direction presentation unit 231 of the body part designation unit 23a of the information designation unit 23 is displayed on the direction presentation unit of the body part designation unit 512a of the information designation screen 500. The part name presented in the part name presentation part 233 of the body part designation part 23a is displayed on the part name presentation part of the body part designation part 512a. Similarly, the presentation content of the body part designating part 23b is displayed on the body part designating part 512b, and the presentation content of the body part designating part 23c is displayed on the body part designating part 512c.

The correction result is stored in a storage device such as a memory of the control unit 11 of the console 10 or a hard disk drive.

  Further, the user sets scan conditions by operating soft keys such as various buttons provided on the information designation screen 500 (S47). The setting content of the scan condition is transmitted to the bed apparatus 20 and the gantry 30.

  Here, the information on the range and part name of the part of the subject P corrected in step S46 may be displayed on the information display unit 32 of the gantry 30.

  The couch device 20 and the gantry 30 perform an X-ray scan of the subject P based on the set scan conditions (S48). Pure raw data collected by the data collection unit 31 in the course of this X-ray scanning is transmitted to the console 10 together with information on the scan position.

  The preprocessing unit 12 of the console 10 generates raw data by performing predetermined preprocessing on the pure raw data (S49).

  The reconstruction function selection unit 132 selects one of the plurality of reconstruction functions stored in the reconstruction function storage unit 133 based on the designation result in step S41 or the correction result in step S46 (S50). Based on the raw data generated by the preprocessing unit 12, the image reconstruction processing unit 131 generates tomographic image data for each slice position using the selected reconstruction function (S51).

  Subsequently, the body part identification processing unit 141 of the information processing unit 14 is designated based on the scan position when the pure raw data based on the image data of each tomographic image is collected by the data collection unit 31. The range of one part is selected from the range of the part of the subject P, and the body part indicated by the image data of the tomographic image is specified (S52). And the information provision process part 142 provides the body part information which shows the specified body part with respect to the image data of each tomographic image (S53).

  Further, the image data classification processing unit 143 of the information processing unit 14 obtains image data of a plurality of tomographic images obtained by the reconstruction unit 13 for each body part based on the designation result in step S41 or the correction result in step S46. Sort (S54).

  Based on the classification result, the control unit 11 classifies the raw data that is the basis of the image data of the tomographic image (S55).

  Then, the control unit 11 sends the image data and / or raw data of the tomographic image to the communication unit 19 based on the classification results in steps S54 and S55. The communication unit 19 transmits the image data and / or raw data of the tomographic image received from the control unit 11 to the workstations 40A and 40B for each classified body part (S56).

  Moreover, the control part 11 sends the image data and / or raw data of a tomographic image to the information recording part 18 for every classified body part based on the classification result in step S54, S55. The information recording unit 18 records the image data and / or raw data of the tomographic image received from the control unit 11 on the medium 18a for each body part (S57). Here, it is desirable to record the body part information provided by the information addition processing unit 142 together with the image data of the tomographic image or the like on the medium 18a.

  Note that, similarly to the first operation example, the control unit 11 performs image data and / or raw data of tomographic images based on the classification results in steps S54 and S55 for a filing system such as PACS as shown in FIG. Can be configured to be transmitted for each body part. The user of the filing system can perform various file operations as described above.

[Fourth operation example: FIG. 13]
Next, referring to FIG. 13, for the image data of the medical image of the subject P acquired in advance, the range of the part of the subject P and the name of the part are specified later using the user interface 15 of the console 10. The operation of the medical image processing system 1 in this case will be described. Note that detailed description of the same processing as in the first operation example will be omitted.

  First, the console 10 (or a computer of a filing system as shown in FIG. 23; the same applies hereinafter) is formed across a plurality of body parts of the subject P from a medical image database (not shown), for example. Image data of a plurality of tomographic images is acquired (S61). It is assumed that body part information is not given to the image data of the tomographic image.

  Further, the console 10 acquires image data of a scanogram of the subject P (S62). At this time, when the image data of the scanogram acquired in the past is stored in the database or the like, the image data of the scanogram is acquired. Further, when the image data of the past scanogram is not stored, the subject P is placed on the top plate 21 and the scanogram is acquired. The presence / absence of image data of a past scanogram is determined based on a result of searching by accessing the database or the like. It is desirable for the console 10 to display the determination result (especially when image data of a past scanogram is not stored) on the display unit 16.

  The control unit 11 causes the display unit 16 to display the acquired scano image (S63). This scano image is displayed on the image display unit 510 in the information designation screen 500 shown in FIGS. The user uses the user interface 15 to specify the region range and region name of the subject P (S64). This designation result is stored in a storage device such as a memory of the control unit 11 of the console 10 or a hard disk drive, for example.

  The control unit 11 sends the image data of the tomographic image acquired in step S61 and the designation result in step S64 to the information processing unit 14. Based on the designation result in step S64, the body part identification processing unit 141 selects a range of one part from the designated range of the part of the subject P for the image data of each tomographic image, and The body part indicated by the image data is specified (S65). And the information provision process part 142 provides the body part information which shows the specified body part with respect to the image data of each tomographic image (S66).

  Further, the image data classification processing unit 143 of the information processing unit 14 classifies the image data of a plurality of tomographic images for each body part based on the designation result in step S64 (S67).

  Here, when the raw data that is the basis of the image data of the tomographic image is also acquired from the database, the control unit 11 classifies the raw data based on the classification result in step S67.

  The control unit 11 sends the image data (and / or raw data) of the tomographic image to the communication unit 19 based on the classification result in step S67. The communication unit 19 transmits the image data of the tomographic image received from the control unit 11 to the workstations 40A and 40B for each classified body part (S68).

  Moreover, the control part 11 sends the image data of a tomographic image to the information recording part 18 for every classified body part based on the classification result in step S67. The information recording unit 18 records the image data of the tomographic image received from the control unit 11 on the medium 18a for each body part (S69). Here, it is desirable to record the body part information provided by the information addition processing unit 142 together with the image data of the tomographic image or the like on the medium 18a.

  Note that, similarly to the first operation example, the control unit 11 transmits tomographic image data based on the classification result in step S67 for each body part to a filing system such as PACS as shown in FIG. It can be constituted as follows. The user of the filing system can perform various file operations as described above.

[Action / Effect]
The operation and effect of the medical image processing system 1 (and the medical image diagnostic apparatus (console 10, bed apparatus 20, gantry 30) and medical image processing apparatus (console 10)) according to this embodiment as described above will be described.

  In addition, the medical image processing system 1 uses the information specifying unit 23 and the user interface 15 to specify the names (part names) of body parts corresponding to the range of the two or more specified part ranges. Can be specified. And the information processing part 14 provides the name of the body part designated corresponding to the range of the selected one part as body part information.

  Thereby, even when medical images of a plurality of parts are captured at a time, body part information indicating the imaging part can be added to the image data of each medical image. It becomes possible to specify an imaging region.

  In addition, the medical image processing system 1 uses the workstations 40A and 40B for the image data to which the body part information is assigned for each designated body part based on the part range and part name designation results of the subject P. Configured to send to. Here, each of the workstations 40A and 40B is used for a specific application (for interpretation of the chest and abdomen).

  Thereby, only the image data of the necessary medical image can be selectively transmitted to each of the workstations 40A and 40B, and the image data of the unnecessary medical image of the body part is not transmitted. Therefore, it is possible to reduce the time required for data transmission processing and storage processing to the workstations 40A and 40B. In addition, the storage capacity for storing data (the storage capacity of a storage device such as a hard disk drive) can be reduced.

  Further, the medical image processing system 1 records the image data to which the body part information is given on the medium 18a for each designated body part based on the designation result of the part range and the part name of the subject P. It is configured as follows.

  Accordingly, it is possible to selectively record medical image data relating to a necessary body part on the medium 18a, to improve convenience, and to reduce the number of consumed media 18a. . In addition, it is possible to reduce the time required for the recording process on the medium 18a.

  In addition, the medical image processing system 1 is configured to display on the information display unit 32 of the gantry 30 the result of designating the range and part name of the subject P using the information designating unit 23 of the bed apparatus 20. ing. Thereby, the user can easily grasp the result of the designation using the information designation unit 23 and can make corrections as appropriate.

  In addition, the medical image processing system 1 can correct the designation result using the information designation unit 23 of the bed apparatus 20 using the user interface 15 of the console 10. This correction is configured to display an image such as a scanogram of the subject P (an image when the subject P is viewed from a certain direction). Accordingly, the designation result on the bed apparatus 20 side can be easily corrected. Further, by referring to a display image such as a scanogram, it is possible to specify the range of the region and the like more accurately.

  In addition, the medical image processing system 1 selects a reconstruction function according to a designation result by the information designation unit 23 or the user interface 15 from a plurality of reconstruction functions stored in the reconstruction function storage unit 133. Since the selected reconstruction function is used to reconstruct the image data of each medical image, a suitable reconstructed image can be acquired for each body part.

  In addition, the medical image processing system 1 is configured to classify image data of a plurality of reconstructed medical images for each body part based on the designation result by the information designation unit 23 and the user interface 15.

  Thereby, the image data of a plurality of medical images acquired at once over two or more body parts can be easily processed for each body part. For example, in addition to the above-described data transfer processing to the workstations 40A and 40B and data recording processing to the medium 18a, image data of a plurality of medical images is stored for each body part and easily read for each body part. Is possible.

  The console 10 (medical image processing apparatus) of this embodiment includes a plurality of medical devices reconstructed based on data reflecting the internal form of the subject P collected by scanning two or more parts of the subject P. An apparatus for processing image data of an image, for each of two or more parts of the subject P, a user interface 15 for designating the range of the part, and each of image data of a plurality of medical images, Based on the scan position when the data that is the basis of the image data is collected, the range of one part is selected from the range of the two or more designated parts, and the selected one part And an information processing unit 14 for giving body part information indicating the body part corresponding to the range to the image data.

  In addition, for each of the two or more designated region ranges, a body part name (part name) corresponding to the region range is designated. And the information processing part 14 provides the name of the body part designated corresponding to the range of the selected one part as body part information.

  According to such a console 10 (medical image processing apparatus), even when medical images of a plurality of parts are photographed at once, body part information indicating the photographing part with respect to image data of each medical image. Therefore, it is possible to specify the imaging region of each medical image.

[Modification]
The embodiment described in detail above is merely an example of a specific configuration for suitably carrying out the present invention. Therefore, arbitrary modifications within the scope of the present invention can be made as appropriate.

[Variation that specifies only the region of the subject]
In the above embodiment, the region name is specified together with the range of the region of the subject P. However, when the same two or more regions are always specified (for example, when the chest and abdomen are always specified) For example, it is not necessary to specify the part name. In this case, the name of the designated part can be stored in advance, and a corresponding part name can be automatically given to each of the two or more designated part ranges. At this time, for example, if the direction of the subject P placed on the bed apparatus 20 is always the same, the range of each designated part and the part name can be easily associated with each other.

  Further, it is also possible to configure the range of the designated part so that the part name is associated based on the z coordinate value representing the range. In this case, for example, parts corresponding to the range of each part based on information such as height, age, and sex included in patient information of the subject P (information described in an electronic medical record or the like can be referred to). Can be configured to specify a name.

[About file operations]
An example of a file operation performed using a medical image processing apparatus such as the console 10 of the above embodiment will be described. For example, the file operation is performed by displaying the file operation screen 600 shown in FIG. 16 on the display unit 16.

  The file operation screen 600 includes an inspection file display unit 610 for displaying a list of files (inspection files) belonging to the hierarchy “inspection (Study)” of the file in DICOM, and a hierarchy “series” included in each inspection file. A series file display unit 620 for displaying a list of files (series files) belonging to the file, an image file display unit 630 for displaying a list of files (image files) belonging to the hierarchy “Image” included in each series file, and Is provided.

The series file display section 620 displays the number of images included in each series file, information indicating the type of reconstruction function used during the image reconstruction process, information indicating the type of filter used, and the like. The image file display unit 630 displays the number of images included in each image file, the scan time, the z coordinate values of the scan start and end positions, the slice thickness, and the like.

  When the user designates one of the examination files listed on the examination file display unit 610 using a mouse or the like, a list of series files belonging to the designated examination file is displayed on the series file display unit 620.

  When one of the series files displayed in the list on the series file display unit 620 is designated using a mouse or the like, a list of image files belonging to the designated series file is displayed on the image file display unit 630.

  Further, when one of the image files displayed as a list on the image file display unit 630 is designated using a mouse or the like, one of a plurality of images belonging to the designated image file is displayed on the image display unit 640. It is like that.

  The file operation screen 600 is provided with various buttons used for file operations and soft keys such as a scroll bar. In particular, the buttons arranged at the lower end of the file operation screen 600 include a transfer button 650 for transferring image data.

  In FIG. 16, two series files are included in the designated inspection file. The designated series file includes one image file. This image file stores 1761 images. One of the 1761 images is displayed on the image display unit 640.

  A file F1 shown in FIG. 17 represents a storage mode of 1761 sheets stored in the image file. The image file F1 includes a plurality of tomographic image data (chest image) obtained by imaging the chest of the subject P, a plurality of tomographic image data (abdomen images) obtained by imaging the abdomen, and a plurality of images obtained by imaging the pelvis. Image data (pelvic image) of the tomographic image of the image is stored.

  The body part information indicated by “part: chest” or the like is given to the image data of each tomographic image in FIG. Further, information (“reconstruction function: FC02” or the like) indicating the type of reconstruction function used at the time of image reconstruction is also given to the image data of each tomographic image. This giving process is executed by the information giving processing unit 142, for example.

  The user can appropriately change the file storage mode by operating the file operation screen 600 using a mouse or the like.

  The file operation screen 600 in FIG. 18 shows a file storage mode different from that in FIGS. In the file operation screen 600 shown in the figure, the specified inspection file includes four series files. In the first series file, image data of one image (for example, a scanogram) is stored. The second series file stores image data of 297 tomographic images obtained by photographing the chest. The third series file stores image data of 401 tomographic images obtained by imaging the abdomen. In the fourth series file, image data of 186 tomographic images obtained by photographing the pelvis (Pelvis) is stored.

As in the case of FIG. 17, the body part information and information indicating the type of the reconstruction function are given to the image data of each tomographic image.

[Data transfer and recording on media]
A transfer process of image data of a tomographic image and a recording process to a medium will be described. Data transfer processing and recording processing are generally performed after file processing as described above. Here, processing in the data storage mode shown in FIGS. 18 and 19 will be described.

  In the above-described embodiment, the case where image data of a tomographic image or the like is transmitted to the workstations 40A and 40B in response to a request from the workstations 40A and 40B has been described. A configuration for determining and transferring data will be described.

  A medical image processing system 1 ′ shown in FIG. 20 represents an example of a medical image processing system according to this modification. Illustration of the bed apparatus 20 and the gantry 30 is omitted. Further, the console 10 'includes, for example, a preprocessing unit, a reconstruction unit, and an information processing unit similar to those in the above-described embodiment, but these are not shown.

  Three workstations 40A, 40B, and 40C are connected to the console 10 'via a network. As in the previous embodiment, the workstation 40A is a chest image workstation, and the workstation 40B is an abdominal image workstation. The workstation 40C is a pelvic image workstation used for interpretation of the pelvic state.

  The console 10 'of the medical image processing system 1' of FIG. 20 includes a plurality (here, two) of information recording units 18A and 18B. Each information recording unit 18A, 18B has the same configuration as the information recording unit 18 of the above-described embodiment. The information recording units 18A and 18B may write data on different types of media, or may write data on the same media.

  Data storage / storage destination information 50 as shown in FIG. 21 is stored in advance in a storage device such as a hard disk drive of the control unit 11. The data transmission destination / storage destination information 50 includes the identification information “ChestWS” of the chest image workstation 40A, the identification information “AdodoWS” of the abdominal image workstation 40B, and the identification information “ "PelvWS" is recorded. Furthermore, the corresponding body parts “chest”, “abdomen”, and “pelvis” are associated with the identification information of each workstation 40A, 40B, 40C.

  Further, in the data transmission destination / save destination information 50, the identification information “drive A” of the information recording unit 18A and the identification information “drive B” of the information recording unit 18B are recorded. Each identification information “drive A” and “drive B” is associated with a body part such as image data of a tomographic image recorded on a medium by the information recording units 18A and 18B. Note that “*” indicating the body part associated with the identification information “drive A” in FIG. 21 indicates that tomographic image data and the like of all body parts is recorded on the medium.

  First, data transfer processing for the workstations 40A to 40C will be described. The processing until the image data (and raw data) of the tomographic image is classified is the same as that in the above-described embodiment. Here, as shown in FIGS. 18 and 19, image data of tomographic images obtained by photographing the chest, abdomen, and pelvis are stored in series files F21, F22, and F23, respectively.

  When the transfer button 650 is clicked, a transfer operation screen 660 as shown in FIG. 22 is popped up. Using this transfer operation screen 660, the user selectively designates a workstation to which data is transferred from among the workstations 40A to 40C. Here, it is assumed that all of the three workstations 40A to 40C are designated.

  In response to the designation of the three workstations 40A to 40C for transferring data, the control unit 11 (the microprocessor) refers to the data transmission destination / storage destination information 50, and stores the chest stored in the series file F21. The identification information “ChestWS” of the image data of the tomographic image obtained by imaging the tomographic image obtained by acquiring the identification information “AdoWS” of the transmission destination of the image data of the tomographic image obtained by imaging the abdomen stored in the series file F22, The identification information “PelvWS” of the transmission destination of the image data of the tomographic image obtained by photographing the pelvis stored in the series file F23 is acquired.

  The control unit 11 controls the communication unit 19 to transmit the image data of the tomographic image stored in the series file F21 toward the workstation 40A corresponding to the identification information “ChestWS”. Similarly, the image data of the tomographic image stored in the series file F22 is transmitted to the workstation 40B corresponding to the identification information “AbdomWS”, and the image data of the tomographic image stored in the series file F23 is identified. The information is transmitted toward the workstation 40C corresponding to the information “PelvWS”.

  Each of the workstations 40A to 40C receives the image data transmitted from the console 10 'and stores it in a storage device such as a hard disk drive. The image data is appropriately read out by the users of the workstations 40A to 40C and used for interpretation or the like.

  According to such a data transfer process, it is possible to selectively transmit only tomographic image data or raw data according to the application to a workstation provided for a specific application. This time can be shortened, and the storage area of the storage device such as the hard disk drive of the workstation is not wasted.

  That is, conventionally, image data of all tomographic images of the chest, abdomen, and pelvis has been transmitted to each of the workstations 40A to 40C, so that a long time is required for the transfer process, and each of the workstations 40A to 40A. A large storage area is necessary because the image data of tomographic images of all body parts is stored in the storage device of 40C. According to this modification, these problems are solved.

  In addition, conventionally, the users of the workstations 40A to 40C have been required to search for images of desired parts from tomographic images of all body parts. According to this modification, the workstations 40A to 40C are used. Since only image data of an image used for interpretation is selectively transferred, the conventional labor is not required.

  Next, recording processing on the medium will be described. The control unit 11 refers to the data transmission destination / storage destination information 50, and identifies the identification information “drive A” of the information recording units 18A and 18B that records tomographic image data of the chest image stored in the series file F21. ”And“ drive B ”, and the identification information“ drive A ”of the information recording unit 18A that records the image data of the tomographic image obtained by photographing the abdomen stored in the series file F22 on the medium is acquired and stored in the series file F23. The identification information “drive A” of the information recording unit 18A for recording the image data of the tomographic image obtained by photographing the stored pelvis on the medium is acquired.

  Based on the identification information acquisition result, the control unit 11 sends the image data stored in the series files F21, F22, and F23 to the information recording unit 18A and records the image data stored in the series file F21 as information recording. Send to section 18B. Each of the information recording units 18A and 18B records the image data received from the control unit 11 on a medium.

  According to such a data recording process, even when a plurality of information recording units are provided, it is possible to record image data of an image of a desired body part on a medium by a desired information recording unit. is there.

  Note that the information recording unit does not need to be provided in the console 10 ', and may be connected to the console 10' via a network such as a LAN (the same applies to the above-described embodiment). In that case, identification information such as a network address of the information recording unit is recorded in the data transmission destination / storage destination information 50. The control unit 11 operates to control the communication unit 19 to transmit image data of an image of a predetermined body part to the information recording unit with reference to identification information such as a network address.

[Information specification processing]
Next, a modified example of the process for designating the range and part name of the part of the subject P will be described. In the above embodiment, the range of the part and the part name are designated using each of the body part designating parts 23a to 23d and the body part designating parts 512a to 512c. This modification automates a part of this processing.

  First, the case where information is designated using the body part designation | designated parts 23a-23d of the bed apparatus 20 is demonstrated. This modification corresponds to the designation of one of the body part designating parts 23a to 23d, and acts to automatically designate the part name of the other body part designating part 23a to 23d. Is.

  For example, when “head” is presented in the part name presenting part 233 of the body part designating part 23a, the body part adjacent to the foot part of the head is the chest, so the part name presenting part 233 of the body part designating part 23b. Automatically presents “chest”. Similarly, the part name presenting unit 233 of the body part designating unit 23c is presented with “abdomen”, and the part name presenting unit 233 of the body part designating unit 23d is presented with “pelvis”.

  This automatic presentation process is executed by, for example, the control unit 11 of the console 10. In that case, information (body part arrangement information) defining an arrangement of body parts (for example, head → chest → abdomen → pelvis → foot) is stored in advance in a storage device such as a hard disk drive of the control unit 11. .

  When a part name is designated by one of the body part designating parts 23 a to 23 d, the designated part name is transmitted from the body part designating part 23 a to 23 d to the console 10. The microprocessor of the control unit 11 identifies the body part to be presented to each of the other body part designating units 23a to 23d based on the designated part name and body part arrangement information, and the identification result is determined as the other part. Are transmitted to the body part designating units 23a to 23d. The other body part designating parts 23a to 23d cause the part name presenting part 233 to present the names of the specified body parts, respectively.

  Next, a case where information is designated using the information designation screen 500 displayed on the display unit 16 of the console 10 will be described. Also in this case, the above-described body part arrangement information is stored in advance in the storage device of the control unit 11. When a part name is designated by one of the body part designation parts 512a to 512c of the information designation screen 500, the control unit 11 designates another body part based on the designated part name and body part arrangement information. The body part to be presented to each of the parts 512a to 512c is specified. And the name of the specified body part is displayed on each of the said other body part designation | designated part 512a-512c.

  According to this modification, it is possible to reduce time and effort for specifying the name of the body part and to shorten the time required for specifying information.
