Description

  The present invention relates to an image diagnosis support apparatus that provides conditions used in past imaging at the time of imaging by a medical image diagnostic apparatus.

  2. Description of the Related Art Conventionally, an image diagnostic apparatus is often used as an apparatus for capturing an image of a subject. Examples of the image diagnostic apparatus include an X-ray CT apparatus, an X-ray diagnostic apparatus, an MRI apparatus, an ultrasonic diagnostic apparatus, and a nuclear medicine diagnostic apparatus. Further, in order to emphasize an organ in a subject with a contrast medium, a contrast medium injection apparatus is often used together with imaging by an image diagnostic apparatus. A contrast medium injection device is a device that injects a contrast medium into a subject.

  When using an image diagnostic apparatus and a contrast medium injection apparatus, it is necessary to set parameters for controlling the behavior of the apparatus. Parameters include the scan start position and range for the diagnostic imaging apparatus (bed movement), the KV / mA of the X-ray tube, the bed movement (beam pitch) in one rotation with respect to the total width of the obtained image slice, etc. Examples include shooting condition information. Further, the parameters include contrast agent injection information such as an injection time and a delay time for the contrast agent injection device.

  Since there are a wide variety of parameters, in recent years, parameters used for shooting may be managed collectively in an object (see, for example, “Patent Document 1”). This is to reduce the burden of parameter setting for the current shooting with reference to the parameters used in the past.

  The object is a DICOM format file including imaging condition information and contrast medium injection information in the data. The object is generated at the end of imaging by the image diagnostic apparatus and the contrast medium injecting apparatus, and is managed in a database by an image diagnostic support apparatus such as PACS on the network. When an image diagnosis is performed using an image diagnosis apparatus or a contrast medium injection apparatus in addition to the image diagnosis apparatus, an object in which imaging condition information and contrast medium injection information used in past imaging are collected from the image diagnosis support apparatus is searched. By referring, the burden of parameter setting can be reduced, and parameter setting errors can be prevented. Furthermore, the conditions of the medical image captured in the past and the medical image captured this time can be made closer, and an image that can be easily compared can be captured.

  The object in which the parameters are collected is purified separately by the diagnostic imaging apparatus and the contrast medium injection apparatus. The diagnostic imaging apparatus generates a shared object in which shooting condition information is collected. The contrast agent injection device generates a contrast agent object in which contrast agent injection information is collected. Since the shared object and the contrast agent object are separate files, the image diagnosis support apparatus manages them separately.

  Therefore, when an image is taken while injecting a contrast medium, the shared object and the contrast medium object must be searched and acquired, respectively. FIG. 11 is a schematic diagram illustrating a communication concept when acquiring a shared object and a contrast agent object.

  As shown in FIG. 11, in the query retrieval method under the DICOM standard, communication for narrowing down in the order of inspection hierarchy, series hierarchy, and object hierarchy is performed in stages, and then communication for acquisition is performed.

  Specifically, first, between an external device such as an image diagnosis device and the image diagnosis support device, for search in the examination hierarchy, transmission / reception of search conditions including a patient ID, and an examination corresponding to the patient ID List is sent and received. Next, for search in the series hierarchy, transmission / reception of a search condition including an examination ID and transmission / reception of a list of series corresponding to the examination ID narrowed down from the examination list are performed. Finally, in order to search the object hierarchy, transmission / reception of search conditions including series ID, SOP class UID and image type, and transmission / reception of a list of objects corresponding to the search conditions narrowed down from the list of series are performed. . Then, a shared object is designated from the finally narrowed-down object list, and communication for acquiring the designated shared object is performed. That is, a total of four communications are established for acquiring the shared object.

  Further, since the shared object and the contrast agent object are managed separately, the communication protocol is also acquired in accordance with the above communication protocol to acquire the contrast agent object, and two communications for searching from the series hierarchy are established. One communication for acquisition is established.

  That is, conventionally, in order to acquire a shared object and a contrast agent object, a total of seven communications are required, at least five times for communication for search and two times for communication for acquisition. Even if the shared object and the contrast agent object are acquired at the same time, a total of six communications are required. Therefore, it takes a long time to actually acquire an object after requesting a search, and there is a problem that work efficiency is lowered.

The transmission / reception unit 2 receives the shared object 10 from the diagnostic imaging apparatus 100. The transmission / reception unit 2 receives the contrast agent object 20 from the contrast agent injection device 200.

  In addition, when there is a request for acquiring the shared object 10 from the request source, the transmission / reception unit 2 transmits the corresponding shared object 10 or the contrast agent object 20 in addition to the shared object 10 to the request source.

  The shared object storage unit 3 is a non-volatile memory that stores the shared object 10 received from the diagnostic imaging apparatus 100. The contrast agent object storage unit 4 is a non-volatile memory that stores the contrast agent object 20 received from the contrast agent injection device 200. The shared object storage unit 3 and the contrast agent object storage unit 4 receive and store the shared object 10 and the contrast agent object 20 received by the transmission / reception unit 2 via the common bus. Further, at the time of acquisition request from the request source, the shared object 10 and the contrast agent object 20 that are stored by accessing the transmission / reception unit 2 are read out.

  The database management system 5 manages the shared object 10 and the contrast agent object 20 in a database. When the image diagnosis support apparatus 1 is an image management system, medical images are also managed in a database. The database management system 5 includes a registration unit 51 and a database 52.

  The registration unit 51 registers the received shared object 10 and contrast agent object 20 in the database 52. The registration unit 51 includes a CPU, and the database 52 includes a nonvolatile memory.

  The scan specifying information 12 includes patient ID, examination date, examination time, examination ID, series ID, image type, SOP class UID, and presence / absence of contrast medium administration. The patient ID is a target ID when scanned by the diagnostic imaging apparatus 100. The examination date is the date when the image diagnostic apparatus 100 scans. The examination time is the time when the image diagnostic apparatus 100 scans. The examination ID is an examination ID when scanned by the diagnostic imaging apparatus 100. In one examination, a plurality of scans may be performed, for example, when a contrast medium is injected or not, and the series ID is an ID of a scan when the image diagnostic apparatus 100 scans. The image type (also referred to as an image type) is information for identifying the characteristics of a photographed image, and information defined in the DICOM standard is described in a multi-value text. The SOP class UID is an ID for identifying the type of the captured image.

  The registration unit 51 reads the SOP instance UID 11 and the scan identification information 12 from the shared object 10 and records them in a new record in the database 52.

  The positioning image 13 is also called a scanogram or a scanogram, and is a plane transmission image of the subject referred to by the operator when the scan range is input to the diagnostic imaging apparatus 100.

  The imaging condition information 14 is information on physical conditions necessary for collecting physical data from which an image is generated from a subject by scanning. The imaging condition information 14 depends on the type of image diagnostic apparatus.

  For example, the imaging condition information 14 of the X-ray CT apparatus includes the scan start position and range (bed movement), the KV / mA of the X-ray tube, and the movement of the bed in one rotation with respect to the total width of the obtained image slice ( Physical quantity such as beam pitch), subject insertion direction at the time of inspection (information on whether the device enters from the foot or head), subject's body position (diagnosis direction, posture), image noise (SD value), etc. Including. Further, for example, the imaging condition information 14 of the MRI apparatus includes the imaging range, patient insertion direction and posture, magnetic field strength, pulse sequence, detection coil type, detection coil installation location, electrocardiographic synchronization, presence / absence of respiratory synchronization, bed ventilation. Parameters such as presence / absence of body, body part at the center of photographing, and wearing position.

  In addition to this, the imaging condition information 14 may include information indicating an image generation condition. Image generation conditions are parameters for reconstructing an image from physical data obtained by shooting. For example, reconstruction range, time phase, image position, direction, thickness, FOV (magnification ratio), reconstruction Filter processing parameters such as functions. The image generation conditions also include conditions used in image processing such as volume rendering and MPR processing executed in various image diagnostic apparatuses 100 and image reference apparatuses. For example, in the case of MPR processing, reference coordinates, normal vectors, slice thicknesses, ranges, and the like correspond.

  The image specifying information 15 includes image object specifying information, key image specifying information, and reference shooting condition specifying information. The image object specifying information is information such as an ID for specifying an object that collects medical images taken under the shooting conditions indicated by the shared object 10. The key image specifying information is information for specifying a key image selected from medical images shot under the shooting conditions indicated by the shared object 10. The reference shooting condition specifying information is the SOP instance UID 11 of the past shared object 10 referred to when the shooting condition indicated by the shared object 10 is set.

  FIG. 4 is a data configuration diagram showing the contrast agent object 20.

  The contrast agent object 20 includes an SOP instance UID 21, scan identification information 22, and contrast agent injection information 23.

  The SOP instance UID 21 is an object ID that distinguishes the attached contrast agent object 20 from other objects. The scan specifying information 22 includes a patient ID, an examination date, an examination time, an examination ID, a series ID, an image type, and an SOP class UID.

  The contrast agent injection information 23 includes an injection time which is an elapsed time when the contrast agent is injected, a scan start delay time based on the start of contrast agent injection, a contrast agent dose, a contrast agent type, and the like. Yes.

  The association processing unit 6 associates the shared object 10 including the imaging condition information 14 in the scan under contrast medium administration with the contrast medium object 20 for the scan. The association processing unit 6 includes a CPU.

  FIG. 5 is a data structure diagram showing a first mode of the shared object 10 to which the contrast agent object 20 is associated.

  As shown in FIG. 5, the association processing unit 6 adds the SOP instance UID 21 of the contrast agent object 20 for the scan under contrast agent administration to the shared object 10 including the imaging condition information 14 in the scan. That is, the SOP instance UID 21 of the contrast agent object 20 is included in the data of the shared object 10.

  The association processing unit 6 searches the shared object 10 including the scan specifying information 22 included in the contrast agent object 20 using the database 52 and adds the SOP instance UID 21 of the contrast agent object 20 to the corresponding shared object 10.

  The scan specifying information 22 used for the search may be a part of the information. For example, the patient ID, the examination date, the examination time, and the accession number are read and an AND search is performed. The accession number is, for example, a number having a correspondence relationship with the order, and the inspection of the same order can be specified by the number. In addition, for example, when an examination ID or an accession number is issued by an RIS (Radiation Information System), a common examination ID or an accession number is attached to the diagnostic imaging apparatus 100 and the contrast medium injector 200. The search may be performed by reading out the ID or the accession number. In addition to the scan specifying information 22 included in the contrast agent object 20, a description of a series indicating that a contrast agent is included, an examination type indicating that a contrast agent is included, and a description of name information of the contrast agent are included. A tag indicating this may be added to the search condition.

  As the examination time, there is a possibility that the time measured by the diagnostic imaging apparatus 100 and the contrast medium injecting apparatus 200 is shifted, and therefore, a time having a predetermined width that is predetermined based on the examination time that the contrast medium object 20 has. Time information that falls within the band may be used as a search condition. The time zone of the predetermined width is stored in the external storage unit by including it in advance in the control program and its data, for example, ± 10 seconds.

  In addition, when the corresponding shared object 10 is not detected even by the search of the association processing unit 6, it may be retried a plurality of times after a predetermined time. This is because the shared object 10 and the contrast medium object 20 are not always transmitted from the diagnostic imaging apparatus 100 and the contrast medium injection apparatus 200 at the same time. The standby time and the number of retries are stored in the external storage unit in advance in the control program and its data, for example, twice at 360 minute intervals.

  Further, the database management system 5 includes a shared object search unit 7 and a contrast agent object search unit 8.

  The shared object search unit 7 searches for the shared object 10 using the database 52. The shared object search unit 7 mainly includes a CPU. When a search condition is input from an external device such as the diagnostic imaging apparatus 100 via the network, the shared object 10 that satisfies the search condition is searched from the database 52. The search condition input from the external device is scan specifying information.

  Input of search conditions, search, and output of search results between the shared object search unit 7 and the external device are performed by communication a plurality of times for each layer by a query retrieval method based on the DICOM standard. First, objects are searched at the inspection level and narrowed down to a group, then the shared objects 10 are searched from the corresponding group at the series level, further narrowed down to a group, and finally the desired shared object 10 is detected from the corresponding group.

  That is, the first search condition input via the network N is the patient ID. When the patient ID is input as a search condition from the external device, the shared object search unit 7 outputs a list of corresponding examinations. Next, the search condition input via the network N is an examination ID. When the inspection ID is input from the external device as a search condition, the shared object search unit 7 outputs a list of corresponding series from the list of inspections. The search conditions finally input via the network N are a series ID, an SOP class UID, an image type, and the like. When these last search conditions are input as search conditions from the external device, the shared object search unit 7 outputs a list of corresponding SOP instance UIDs 11 from the list of series. The shared object search unit 7 refers to the database 52 based on the input search condition and gradually detects the target shared object 10.

  The contrast agent object search unit 8 searches for the contrast agent object 20 using the SOP instance UID 21. The contrast agent object search unit 8 is mainly configured to include a CPU. If the SOP instance UID 21 of the contrast agent object 20 is added to the shared object 10 detected by the shared object search unit 7, the contrast agent object search unit 8 searches for the contrast agent object 20 having the SOP instance UID 21.

  6 and 7 are time charts showing a first association operation in such an image diagnosis support apparatus 1. FIG.

  As shown in FIG. 6, when the transmission / reception unit 2 receives the shared object 10 (S01, Yes), the transmission / reception unit 2 stores the shared object 10 in the shared object storage unit 3 (S02). The registration unit 51 registers the received shared object 10 in the database 52 (S03).

  As shown in FIG. 7, when the transmission / reception unit 2 receives the contrast medium object 20 (S04, Yes), it is stored in the contrast medium object storage unit 4 (S05). The registration unit 51 registers the received contrast agent object 20 in the database 52 (S06).

  When the correlation processing unit 6 receives the contrast agent object 20, the association processing unit 6 reads the scan specifying information 22 and the SOP instance UID 21 from the received contrast agent object 20 (S07). Then, the association processing unit 6 refers to the database 52 and searches for the shared object 10 having the scan specific information 12 that is the same as the scan specific information 22 (S08).

  If the corresponding shared object 10 is not detected (S08, No), the associating unit 6 does not reach the number of retries (S09, No), and searches again after a predetermined time (S10) (S08). ).

  If the corresponding shared object 10 is detected (S08, Yes), the association processing unit 6 adds the SOP instance UID 21 of the contrast agent object 20 read in S07 to the detected shared object 10 (S11).

  As a result, the shared object 10 and the contrast medium object 20 are associated with each other, and the contrast medium object 20 can be acquired as the shared object 10 is searched.

  FIG. 8 is a flowchart showing a first search operation in such an image diagnosis support apparatus 1. FIG. 9 is a schematic diagram showing an aspect of the first search operation.

  First, the transmission / reception unit 2 receives a patient ID as a search condition from the diagnostic imaging apparatus 100 as an input source via the network N (S21). The shared object search unit 7 refers to the database 52 to search for a group of objects having the received patient ID in the scan specifying information 12 (S22), and the transmission / reception unit 2 uses the search results as a list to input the network N (S23).

  Next, the transmission / reception unit 2 receives the examination ID as a search condition from the diagnostic imaging apparatus 100 as the input source via the network N (S24). The shared object search unit 7 refers to the database 52 to search for a group of shared objects 10 having the received examination ID in the scan specifying information 12 from the group searched in S22 (S25). The results are transmitted as a list to the input source via the network N (S26).

  Next, the transmitting / receiving unit 2 receives the series ID, the SOP class UID, and the image type as search conditions from the diagnostic imaging apparatus 100 that is the input source via the network N (S27). The shared object search unit 7 refers to the database 52 and searches the list of shared objects 10 having the received search condition in the scan specifying information 12 from the group searched in S25 (S28). The result is transmitted to the input source via the network N (S29).

  When the SOP instance UID of the shared object 10 is presented from the diagnostic imaging apparatus 100 and an acquisition request is received, the transmission / reception unit 2 reads the shared object 10 having the presented SOP instance UID (S30). Further, the contrast agent object search unit 8 searches the SOP instance UID 21 of the contrast agent object 20 from the read shared object 10 (S31). If the SOP instance UID 21 of the contrast agent object 20 is additionally written (S31, Yes), the SOP instance UID 21 is read (S32), and the contrast agent object 20 having the read SOP instance UID 21 is searched with reference to the database 52. (S33).

  If the contrast agent object 20 is not found (S31, No), the transmission / reception unit 2 transmits only the shared object 10 that has been read out to the input source (S35), and if the contrast agent object 20 exists (S31, Yes). ), The searched contrast agent object 20 is also transmitted to the input source (S34).

  Thereby, the input source and the diagnostic imaging support apparatus 1 can acquire the shared object 10 and the contrast agent object 20 through three communications for searching and one communications for acquiring an object.

  FIG. 10 is a data structure diagram showing a second mode of the shared object 10 to which the contrast agent object 20 is associated.

  In the shared object 10, the contrast medium injection information 23 of the contrast medium object 20 may be additionally recorded. After searching for the shared object 10 having the same scan specifying information 12 as the scan specifying information 22 of the contrast agent object 20, the contrast agent injection information 23 is read from the contrast agent object 20 and added to the corresponding shared object 10. Alternatively, the contrast medium object 20 itself or a part of the contrast medium injection information 23 may be additionally recorded.

  When the contrast medium injection information 23 or the like is added to the shared object 10, only the corresponding shared object 10 is searched without searching for the contrast medium object 20 in the contrast medium object searching unit 8 after the search of the shared object 10 based on the search condition. Is sent to the input source. Since the shared object 10 also includes the contrast agent injection information 23 included in the contrast agent object 20, it is possible to refer to the contrast agent injection information 23 at the input source.

  In this case, the association processing unit 6 prepares a table in which the storage destinations of the contrast medium object 20 and the shared object 10 are defined, and copies the contrast medium injection information 23 from the contrast medium object 20 to the shared object 10 according to the table. For example, a table is created in which the inspection ID, series ID, SOP instance UID 21 of the contrast agent object 20, the acquisition destination of the contrast agent injection information 23 on the memory, and the storage destination of the shared object 10 are paired.
