Description

  The present invention relates to a medical information processing apparatus.

  In the medical field, various image generation devices (also called modalities) such as CR (Computed Radiography), CT (Computed Tomography), and MRI (Magnetic Resonance Imaging), and PACS (Picture Archiving and Communication System) System is used. In this system, medical image data captured and digitized by an image generation apparatus is managed by PACS and used for medical examinations and the like.

Photographing is performed according to order information issued in RIS (Radiology Information System) or the like. The order information is for instructing the patient to be imaged, the imaging content, and the like, and is composed of patient information related to the patient, examination information indicating the imaging content, and the like.
In the above system, based on the order information, patient information (name, gender, etc.) and examination information (modality used for examination, imaging part, Information such as the shooting direction and the shooting date and time) is attached, and individual medical images can be identified by the accompanying information.

  Conventionally, before transferring a medical image generated by an image generation device to a PACS, a radiographer or the like browses the medical image to check whether the image has been taken as instructed or to obtain an image density suitable for interpretation. A system capable of an image inspection operation for performing an image processing operation is disclosed (for example, see Patent Document 1). This is because it is inefficient for an interpretation doctor who browses medical images in PACS to perform such confirmation and operation step by step.

In the above-described system, an image list is created for medical images to be subjected to an image inspection operation, and the image list is constantly updated to facilitate the image inspection operation as described above.
JP 2005-224472 A

In the system described above, image numbers are assigned in the order in which medical images are taken and generated for each examination. When displaying a medical image when performing an image inspection operation or when an interpreting doctor performs an interpretation, it is common to display the medical images in the order of the image numbers.
However, at the shooting site, the order of shooting may be determined depending on the availability of the image generation device, ease of shooting, and the like. In this case, the imaging order may not be an order suitable for interpretation for the interpretation doctor. Although it is possible to change the arrangement order of the medical images on the display, it is troublesome for the interpretation doctor to perform the operation one by one. In addition to changing the display order, it is necessary to adjust the image number itself of the medical image.

Become.

  According to the sixth aspect of the present invention, even in a medical image belonging to a series, the arrangement order within the series can be changed. Since the series number attached to the medical image itself is rewritten according to the change in the arrangement order, the medical image can be displayed in the arrangement order as changed in the medical information processing apparatus even at the medical image providing destination. Become.

First, the configuration will be described.
FIG. 1 shows a system configuration of the medical image system 100.
As shown in FIG. 1, the medical image system 100 includes a RIS 1, an image generation device 2, an image inspection device 3, a PACS 4, and a control device 5. The devices 1 to 5 are connected via a network N.

  The RIS1 is a radiology information system that manages information in the radiology department, and generates and manages order information. The order information is generated in response to a doctor's order information registration operation, and includes patient information of a patient to be imaged, examination information regarding examination contents, and the like. The patient information includes information such as the patient's name, patient ID (ID assigned to each patient), and sex. The inspection information includes, for example, an inspection ID (an ID given to individually identify the inspection), a modality used for imaging (name of CR apparatus, CT apparatus, etc.), an imaging method (simple imaging, enlarged imaging, etc.), imaging Information such as a part (chest, abdomen, etc.), imaging direction (front, oblique, etc.), imaging position (standing position, supine position, etc.) is included.

The RIS1 generates order information in a necessary photographing unit. For example, even when the imaging direction is different between the chest front and the chest side by the same CR device, two pieces of order information are generated because imaging is performed. On the other hand, when a tomographic image is taken for a certain region of the abdomen using the CT apparatus, a plurality of medical images are generated. However, since one imaging is performed as an imaging unit, only one order information is generated.
The RIS 1 adds and manages an order ID (ID assigned to individual order information) to the generated order information. Then, the order information is transmitted to the control device 5.

  The image generation device 2 is an image generation device that captures a patient and generates medical image data. In this embodiment, the image generation apparatuses 2a to 2c of the types of CT apparatus, CR apparatus, and MRI apparatus are provided, but other types of modalities such as an endoscopic imaging apparatus and an ultrasonic imaging apparatus are applied. It is also possible.

  The image generation device 2 images the patient according to the order information distributed from the control device 5. Then, the generated medical image data is attached with patient information such as examination ID and patient ID, and examination information included in the order information to enable identification of the medical image, and then transmitted to the control device 5. Information can be added by writing information in the header area of the medical image. Note that the image generation device 2 transmits information related to the execution of imaging and generation of a medical image to the control device 5 together with the medical image.

The imaging apparatus 3 is a medical information processing apparatus according to the present embodiment, and is used for performing an imaging operation on a medical image.
The imaging operation refers to an operation for confirming whether a medical image is generated according to the order information, an image quality operation for the medical image, an operation for correcting the order information, or the like.

  As shown in FIG. 2, the image inspection apparatus 3 includes a control unit 31, an operation unit 32, a display unit 33, a communication unit 34, a storage unit 35, an image memory 36, and the like.

  The control unit 31 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like. The control unit 31 reads the control program from the storage unit 35, performs various calculations in cooperation with the control program, and centrally controls the operations of the units 32-36.

The operation unit 32 includes a keyboard, a mouse, and the like, generates operation signals corresponding to these operations, and outputs them to the control unit 31.
The display unit 33 includes an LCD (Liquid Crystal Display) or the like, and displays various operation screens, medical images, and the like according to display control of the control unit 31.

The communication unit 34 includes a communication interface such as a network interface card, and communicates with an external device on the network N according to the communication control of the control unit 31.
The storage unit 35 includes a recording medium such as a hard disk or a semiconductor memory.
The storage unit 35 stores various programs such as a control program executed by the control unit 31 as well as data necessary for executing the program.

The image memory 36 is composed of a recording medium such as a hard disk or a semiconductor memory.
The image memory 36 stores medical image data generated by the image generation apparatus 2. Medical images are stored separately for those waiting for image detection for which image inspection operation has not yet been performed and those for which image inspection operation has been performed.

  The PACS 4 is configured to include a terminal device for a doctor to interpret the stored medical image, in addition to an image server that stores data of a medical image that has undergone an imaging operation in the imaging apparatus 3. . When the image interpretation request information is received from the terminal device, the medical image stored in the image server is distributed to the terminal device. By displaying the medical image distributed by the terminal device, the doctor can interpret the image.

The control device 5 comprehensively controls the flow of order information and the photographing of medical images.
The control device 5 distributes the order information distributed from the RIS 1 to the image generation device 2 specified by the order information and transmits it to the image inspection device 3. On the other hand, when the medical image data is received from the image generating apparatus 2, in addition to the patient information and the examination information included in the order information corresponding to the medical image, series information, detailed image information, and the like are generated and attached.

FIG. 3 shows an example of incidental information.
As shown in FIG. 3, the incidental information includes patient information T1, examination information T2, series information T3, and detailed image information T4. Here, the series information T3 refers to information about a series to which the medical image belongs when the medical images related to each other are handled as belonging to a series of series. For example, in a CT apparatus, since a tomogram over a certain range, such as from the chest to the abdomen, is taken, a plurality of medical images (tomographic images) in units of 100 to several thousand images are generated by one imaging. In such a case, each tomographic image obtained by the same imaging is handled as belonging to one series. The control device 5 generates information such as the examination site in the series as series information T3. A series number is assigned to each series, and the same series information T3 is attached to all medical images belonging to the same series. Information necessary for generating the series information T3 is acquired from the image generating device 2.

The detailed image information T4 is information related to a medical image. For example, as shown in FIG. 3, it is information such as allocation bits and image generation time when a medical image is generated. The control device 5 acquires these pieces of information from the image generation device 2 and generates detailed image information T4. Further, the control device 5 assigns an image number to the medical image in order information units or series units. The image number is a number indicating the generation order of medical images. For example, in the case of order information for capturing two images of the front of the chest with the CR device, the image numbers of the generated two medical images are assigned “1” and “2”, respectively, in the order of generation. In addition, when there are two pieces of order information for photographing one front of the chest and one side of the chest, the image number is “1”. On the other hand, for medical images belonging to a series, image numbers are assigned in the order of generation within the series.
Since the history information T5 is attached by the imaging device 3, details will be described later.

  Note that the image number and the series number are elements that determine the display order of the medical images when the medical images are displayed later. That is, when medical images are displayed on the image inspection device 3 or the terminal device of the PACS 4, the medical images are displayed in order of series number and image number.

  Each information T1 to T5 is given patient information LID, examination information LID, series information LID, detailed image information LID, and history information LID unique to each information. Patient information LID is included in examination information T2, and similarly, examination information LID in series information T3, patient information LID, examination information LID, series information LID in image detailed information T4, series information LID, and image detailed information LID in history information T5. By including, each information T1-T5 is matched.

Next, the operation will be described.
The overall processing flow of the medical image system 100 will be described.
The medical image system 100 is roughly divided into (1) order information generation, (2) imaging based on order information, generation of a medical image, (3) imaging processing for a medical image, and (4) transfer to PACS4. Go through.

(1) Generation of Order Information The RIS 1 generates order information in response to an order information registration operation. The RIS 1 attaches an order ID to the generated order information and transmits it to the control device 5.
(2) Imaging based on order information, generation of medical image The control device 5 refers to the order information and distributes the order information to the designated image generation device 2. In addition, the same order information is transmitted to the imaging device 3.
The image generation device 2 displays the patient name, the imaging region, and the like on the display unit based on the order information in order to show the imaging engineer the contents of the order information. Then, shooting is performed according to the shooting instruction operation. Thereafter, medical image data is generated and transmitted to the control device 5. The control device 5 attaches patient information, examination information, series information, and detailed image information included in the order information to the medical image and transfers them to the imaging device 3.

(3) Imaging processing for medical images The imaging device 3 performs various imaging processing according to the imaging operation of the examiner. The image inspection process will be described later.
(4) Transfer to PACS 4 The image inspection device 3 sequentially transfers the medical image data for which the image detection processing has been completed to the PACS 4. The PACS 4 stores the medical image. Then, a medical image is distributed in response to a request from a terminal device used by an interpreting doctor, and is used for interpretation and medical examination by a doctor.

Next, the image detection process in the image detection apparatus 3 will be described with reference to FIG.
FIG. 4 is a flowchart for explaining the flow of the image inspection process.
First, the control unit 31 reads a medical image stored in the image memory 36. And the process which checks the consistency with the additional information of the said medical image and the order information corresponding to the read medical image among the order information transmitted from the control apparatus 5 is performed (step S1). This is a process performed to confirm whether or not a medical image is generated according to the order information. Specifically, the order information, the patient information included in the accompanying information, and the examination information are collated, and if they match, it is determined that there is consistency, and if they do not match, it is determined that there is no consistency. The control unit 31 displays the result of this check on the display unit 33. For example, in the list of order information, a color that is not consistent is colored.

Next, image density adjustment processing is executed (step S2).
A medical image has an image density that is easy to interpret depending on an imaging region or the like. The control unit 31 refers to the supplementary information of the medical image, determines the imaging region, and then performs gradation conversion of the medical image using a gradation conversion table (lookup table) created in advance according to the imaging region. Do. Alternatively, the density adjustment of the medical image is performed in accordance with the adjustment operation of the density and contrast of the examiner.

Next, a process for changing the arrangement order of medical images is performed (step S3).
This is a process of changing an image number or the like that determines the arrangement order of medical images in accordance with an operation for changing the display order of medical images. Details will be described later.

When the arrangement order is changed, an inspection range setting process is performed (step S4).
The image inspection range refers to a range of medical images used for interpretation by a doctor. For example, in the case of a CT apparatus, a tomographic image of 100 to several thousand images can be obtained from the chest to the abdomen, but imaging is performed with a margin portion in a designated portion to ensure a medical image of a portion necessary for diagnosis. Is done. For this reason, not all tomographic images are essential, and an operation for extracting only a portion necessary for interpretation is necessary. In the detection range setting process, the control unit 31 determines a medical image in a specified range from among a series of medical images as the detection range in accordance with the operation of specifying the detection range by the examiner. Then, flag information indicating the start point or end point of the image detection range is attached to the medical image determined as the start point or end point of the image detection range (see image detailed information T4 in FIG. 3).

In addition, correction processing of information such as order information or supplementary information of medical images is executed (step S5). The information correction process is a process of rewriting the order information or incidental information for a medical image that is not consistent with the order information in step S2. The rewriting is performed by the control unit 31 in accordance with the correction operation of the examiner (for example, the input operation of the name after correction of the patient).
When all the above-described image inspection processes are completed, the control unit 31 performs a distribution process for transmitting the image data of the medical image that has already been imaged to the PACS 4 via the communication unit 34 (step S6).

Next, the process of changing the arrangement order of medical images in step S3 will be described in detail with reference to FIG.
As shown in FIG. 5, the control unit 31 displays an image detection waiting list on the display unit 33 (step S <b> 11). The examination waiting list is a list of order information of medical images that have not been subjected to examination processing. When an operation for selecting order information to be imaged from the image waiting list is performed via the operation unit 32, the control unit 31 reads a medical image corresponding to the selected order information from the image memory 36. . Then, an image number is specified with reference to the accompanying information of the read medical image, a thumbnail image of the medical image is generated, and the thumbnail images are arranged and displayed in a list in the specified image number (step S12).

FIG. 6 is a view showing the waiting list screen d1.
In the waiting list screen d1, the control unit 31 displays a list area d11 for displaying a list of order information of medical images that have not been subjected to an imaging process, and thumbnail images of medical images corresponding to the order information selected in the list area d11. A search area d13 for searching for desired order information from the order information displayed as a list in the thumbnail area d12 and the list area d11.

In the list area d11, as shown in FIG. 6, among the order information received from the control device 5, the order information of the medical image that has not been subjected to the image inspection process is displayed. Based on the order information, the control unit 31 displays information such as the order information reception date and time, examination ID, patient ID, patient name, modality, imaging method, imaging region, imaging direction, and the like.
Note that the processing result of the consistency check process described above may be displayed here. For example, for the order information determined to be inconsistent, the order information is given a red color in the list area d11. By displaying the information in such a manner that it can be distinguished from other order information that is consistent, the examiner can easily determine the order information that is determined to be inconsistent.

In the thumbnail area d12, the control unit 31 displays the thumbnail images g in the order of the image numbers attached to the medical images. Since the image numbers are issued in the order in which they are generated in the image generation apparatus 2, the arrangement order of the thumbnail images g matches the generation order of the medical images. The thumbnail image g is used by the examiner to check the medical image and change the arrangement order of the medical images.
In addition, as a method for displaying the thumbnail image g, the control unit 31 provides a display switching menu k1 for switching whether to display for each series unit in the thumbnail area d12.

  In the search area d13, the control unit 31 provides an input area for inputting the examination ID, patient ID, and the like of desired order information as a search keyword. At the time of retrieval, the control unit 31 retrieves order information having supplementary information that matches the information input in this input area. The retrieved order information is given a blue color in the list area d11.

When an instruction operation for displaying each series unit is performed by the display switching menu k1 via the operation unit 32 on the image-waiting list screen d1 (step S13; Y), the process proceeds to step S18. On the other hand, if there is no such instruction operation (step S13; N), the process proceeds to step S14.
First, the case where there is no instruction operation will be described from the process of step S14.

On the waiting list screen d1, it is possible to change the arrangement order of the medical images by moving the position of the thumbnail image g.
The position moving operation can be performed by dragging and dropping the thumbnail image g via the operation unit 32. As illustrated in FIG. 7, an example will be described in which thumbnail images g (numbers displayed on the upper left of the thumbnail images in FIG. 7 indicate the image numbers of the medical images) are arranged in the order of the medical image image numbers. Then, if the medical image with the image number 4 is to be arranged between the image number 2 and the image number 3, the thumbnail image g with the image number 4 is dragged, and the thumbnail images g with the image numbers 2, 3 Perform a drop operation.

  When the operation of moving the position of the thumbnail image g is performed via the operation unit 32 (step S14; Y), the control unit 31 changes the arrangement order of the moved thumbnail images g according to the moved position. Then, it is displayed again on the display unit 33 (step S15). In the example of FIG. 7, the positions of the thumbnail images g of the image number 3 and the image number 4 are exchanged to change the arrangement order, and are displayed again in the changed arrangement order.

  Next, the control unit 31 rewrites and changes the information of the image number attached to the medical image in accordance with the changed arrangement order (step S15). Specifically, since the image number information is included in the detailed image information T4 (see FIG. 3) attached to the medical image, it is rewritten to the changed image number (step S16).

  After the change, the control unit 31 generates history information regarding the change of the image number (step S17). For example, history information T5 as shown in FIG. 3 is generated. For example, it is information indicating history contents such as information on a change date and time, an image number before change, and information on an image number after change. The control unit 31 includes the history information T5 including the series information LID and the image detailed information LID attached to the medical image to be rewritten in the history information T5, and the history information T5 and the already-attached series information T3 and image detailed information T4. Perform the association. Further, the control unit 31 generates a history ID for individually identifying the history information and includes the history ID in the history information T5.

Next, a case where the display operation in series units is instructed will be described from the processing in step S18.
In this case, the control unit 31 displays the thumbnail image g in series units in the thumbnail area d12 (step S18). Specifically, the series number attached to the medical image corresponding to the selected order information is referenced to determine the series to which the medical image belongs. Further, referring to the image number attached to the medical image, the medical image of the first image number of each series is used as the representative image of the series, and the thumbnail images g of the medical images are displayed side by side in the order of the series number.

  For example, as shown in FIG. 8, when CT imaging is performed in the direction indicated by the arrow A by dividing the area from the chest to the abdomen into four ranges by a CT apparatus in a certain examination, four series of medical images are obtained. Will be. At this time, the medical images belonging to each series are given series numbers SE1, SE2, SE3, and SE4 in the order of imaging, and the medical images are assigned image numbers 1 to n (n is the number in the series) in the order generated in each series. (Indicates the image number of the last generated medical image).

  Therefore, in the thumbnail region d12, as shown in FIG. 9A, the thumbnail image g is represented in the order of series number SE1, SE2, SE3, SE4, with the medical image of image number 1 in the series of the series number as a representative. Will be displayed. In FIG. 9, the reference numerals such as SE1 [1] attached to the thumbnail image g indicate the series numbers SE1 to SE4, and the numbers in parentheses indicate the image numbers.

In the thumbnail area d12 displayed in this way, it is possible to change the arrangement order of the medical images in series units. The change operation is performed by moving the thumbnail image g as in the case of changing the arrangement order of the medical images in units of images.
For example, in the case of the arrangement order of series numbers SE1 to SE4, medical images are displayed in the order of series numbers even when interpretation is performed. Therefore, the position of the imaging part of the medical image to be interpreted is vertically (See FIG. 8). When it is preferable to interpret images in the order of chest → abdomen, it is necessary to arrange medical images in the order of series numbers SE1, SE4, SE2, and SE3. In this case, in FIG. 9A, the thumbnail image g with the series number SE4 is dragged and dropped between the thumbnail images g with the series numbers SE1 and SE2.

  When the moving operation is performed via the operation unit 32 (step S19; Y), the control unit 31 changes the arrangement order of the thumbnail images g according to the position after the movement, and the thumbnail images are changed in the changed arrangement order. g is displayed again (step S20). FIG. 9B is a diagram illustrating after re-display. As shown in FIG. 9B, the thumbnail image g with the series number SE4 is arranged next to the thumbnail image g with the series number SE1, and the arrangement order of the thumbnail images g with the series numbers SE2 and SE3 is lowered. Thereafter, the control unit 31 rewrites and changes the information of the series number attached to the medical image according to the changed arrangement order (step S21).

  Furthermore, in the thumbnail area d12, in addition to changing the arrangement order of the series units, it is possible to change the arrangement order of medical images in the series. At the time of display in series units, the control unit 31 displays a rearrangement menu k2 as shown in FIG. In this rearrangement menu k2, it is possible to select the order of medical images in the series ascending (image number 1 → n) or descending (image number n → 1). The examiner first selects a thumbnail image g of a series to be rearranged, and then performs an ascending or descending selection operation from the rearrangement menu k2.

For example, as described above, when the arrangement order of the series numbers is set to SE1, SE4, SE2, and SE3, the imaging regions are arranged in the order of chest to abdomen in series units. However, since all the medical images are in ascending order, in the series of the series numbers SE4 and SE3, the medical images are arranged in the order of the abdominal part → chest part. Therefore, when the order of medical images in the series is to be interpreted from the chest to the abdomen, it is necessary to set the medical images in descending order.
In this case, the image examiner performs an operation of selecting the descending order from the rearrangement menu k2 after selecting the thumbnail image g of the series number SE4 in the thumbnail area d12 shown in FIG. 9B. The same operation is performed for the series number SE3.

  When the above operation is performed (step S22; Y), the control unit 31 arranges the medical images belonging to the series of the series numbers SE3 and SE4 selected by the thumbnail image g in the selected order (ascending order or descending order). Change (step S23). When descending order is selected in the above example, the arrangement order is reversed with the medical image with the image number n as the head. When the ascending order is selected, the arrangement order is reversed with the medical image whose image number is 1 as the head. When the change is repeated a plurality of times, the ascending order and descending order are determined based on the original image number. The original image number is an image number assigned at the beginning of generation of a medical image. That is, the order in which the original image number is 1 → n is called ascending order, and the order in which the original image number is n → 1 is called descending order. The original image number can be grasped by referring to the history information T5.

  In the thumbnail area d12, for the series numbers SE3 and SE4, the thumbnail image of the medical image with the image number 1 is displayed. However, the top medical image is changed from the image number 1 to the image number n by changing in descending order. Therefore, as shown in FIG. 9C, the control unit 31 changes the thumbnail image g to the thumbnail image g related to the medical image with the image number n and redisplays it.

  Next, the control unit 31 rewrites and changes the information of the image number attached to the medical image related to the change according to the change in the arrangement order of the medical images in the series (step S24). When the arrangement order of the medical images belonging to the series of the series number SE4 is changed from ascending order to descending order, the image numbers are rewritten for all the medical images belonging to the series.

  Thereafter, the control unit 31 generates history information T5 regarding the change of the series number or the image number (step S17). When the series number is changed, the history information T5 includes the series number before the change and the series number after the change as shown in FIG. Further, if the image number is also changed, the image numbers before and after the change are similarly included.

  As described above, according to the present embodiment, the thumbnail images of the medical images are displayed in a list in the order of the image numbers attached to the medical images in the imaging device 3, and the medical images are arranged using the thumbnail images. The order can be changed. Then, the display order of thumbnail images is changed according to the change operation, and the image number attached to the medical image is rewritten and changed. Therefore, when the medical image is later displayed on the terminal device of the PACS 4, the medical image is displayed in the order of the image numbers attached to the medical image.
