Description

  Embodiments described herein relate generally to an inspection data storage management device, a late inspection apparatus, and an inspection data management system.

  In current general medical facilities, various diagnostic imaging devices and treatment devices are connected to each other via a network, and these devices are properly used in prevention, diagnosis, treatment, and clinical settings, and used in combination. Is done.

  For example, medical images obtained by mammography (also referred to as “MMG”) are used for regular breast examination. The medical image is assigned a patient ID, examination ID, apparatus ID, and image ID, and is stored in the examination data storage management apparatus. Address information is associated with the image ID (for example, Patent Document 1). The inspection ID, device ID, image ID, and address information may be referred to as supplementary information. Further, the inspection data storage management device may be referred to as PACS.

  In response to an operation by a doctor (primary doctor and / or interpretation doctor), the interpretation apparatus acquires a medical image obtained by taking mammography from the PACS and displays it. A doctor interprets an image with reference to a medical image. When a more detailed examination is required based on the result of interpretation, the interpretation device receives an instruction from a doctor for detailed examination, and the interpretation device is sent to an in-hospital information management system / radiation information management system (hereinafter referred to as an in-hospital information management system or the like). Requesting the creation of reservation examination information indicating reservation of the ultrasonic diagnostic apparatus. The in-hospital information management system or the like sends the scheduled examination information to the ultrasonic diagnostic apparatus. In a close examination, a medical image obtained by mammography is referred to.

  Here, a device used for the advance inspection such as mammography may be referred to as “first inspection device”, and a device used for the subsequent inspection such as an ultrasonic diagnostic apparatus may be referred to as “subsequent inspection device”. In-hospital information management systems are sometimes referred to as HIS / RIS.

  Furthermore, for example, a CT image obtained by imaging with an X-ray CT apparatus at the time of diagnosis and an ultrasonic image obtained by imaging with an ultrasonic diagnostic apparatus during treatment fluoroscopy are displayed simultaneously. At this time, the X-ray CT apparatus is a “first inspection apparatus”, and the ultrasonic diagnostic apparatus is a “subsequent inspection apparatus”. These medical images are also attached with accompanying information (patient ID, examination ID, apparatus ID, image ID, address information) and stored in the examination data storage management apparatus (PACS).

  As described above, a medical image obtained by being imaged by the advance inspection device is referred to and / or displayed in the subsequent inspection. In addition, there are cases where a medical image obtained by taking a picture with a first examination device and actually referred to and / or displayed in a subsequent examination, and the target image is referred to as a “reference image”. Furthermore, when it is referred to as inspection data, there are a case where only “reference image” is indicated and a case where “reference image and supplementary information” are indicated.

Japanese Patent Laid-Open No. 5-108733

  FIG. 1 is a timing chart of an inspection data management system according to a comparative example. As shown in FIG. 1, a medical image is taken by an advance inspection device (here, MMG). The medical image is accompanied by a patient ID, an examination ID, a device ID, and an image ID, and is sent to the examination data storage management device (PACS) ("examination data retrieval request", "examination data retrieval response" shown in FIG. "Inspection data reception request", "Inspection data reception response"). The medical image is stored in an examination data storage management device (PACS).

  Next, in response to an operation by the doctor, the image interpretation apparatus acquires a medical image from the examination data storage management apparatus (PACS). The doctor interprets the acquired medical image and determines whether or not a subsequent inspection (final inspection) is necessary (“detailed determination” shown in FIG. 1). Here, the medical image acquired from the PACS at the time of interpretation is a reference image that is also referred to in the subsequent examination. Next, when a subsequent examination is required, the doctor requests the hospital information management system or the like (HIS / RIS) to create scheduled examination information. The in-hospital information management system or the like creates reservation examination information ("preparation required for detailed examination shown in FIG. 1").

  In response to a regular operation (for example, at the start of work) by the operator, the subsequent inspection device (in this case, an ultrasonic diagnostic apparatus) inquires of the in-hospital information management system whether there is reservation inspection information (see “Reservation” shown in FIG. 1). Inspection information request "," Reserved inspection information response "). When there is scheduled examination information, the operator uses search and reception, which is one of DICOM functions, and receives an input of a plurality of search keys for patient ID, examination ID, and apparatus ID by the operator. Requests PACS to retrieve the image ID. Next, in response to the operation of the operator, the subsequent inspection device requests the inspection data storage management device (PACS) to transmit the reference image based on the address information associated with the image ID (FIG. 1). "Inspection data search request", "Inspection data search response", "Inspection data reception request", "Inspection data reception response"). Thereby, the reference image referred in the subsequent inspection is acquired. After the reference image is acquired, the subsequent inspection is started (“inspection start notification” shown in FIG. 1).

  In the current mainstream 1000BASE-T Ethernet (registered trademark) communication, it takes about 0.2 to 0.3 seconds to display the search result of one examination, and about 1 second to transfer one reference image (still image). If a subsequent inspection device retrieves and receives 20 inspections and 100 inspection images from each of 100 inspection images for PACS, 4 to 6 seconds are displayed in the search result display of 20 inspections, and 100 is transferred to 100 reference images. (= 100 * 1) seconds, it takes 104 to 106 seconds (about 2 minutes or less) in total.

  However, there is a problem in that, when search requests for reference images that are referred to in the subsequent inspection are concentrated at the start of business, for example, if the PACS processing capability is insufficient, transfer of the reference image is delayed, and the start of the subsequent inspection may be delayed. It was.

  In addition, in order to specify the reference image, it is necessary to input a plurality of search keys (patient ID, examination ID, and device ID), which has a problem in that it hinders improvement in operability.

  This embodiment solves the above problem, prevents the transfer of the reference image from being delayed, and further, improves the operability of the inspection data storage management device, the subsequent inspection device, and An object is to provide an inspection data management system.

In order to solve the above-described problem, the inspection data storage management device according to the embodiment includes a storage unit and a management unit. A memory | storage part memorize | stores beforehand the test | inspection data containing the image acquired by image | photographing by the advance test | inspection with respect to a patient. The management unit receives the instruction of the subsequent inspection required from the image interpretation device based on the inspection data and the interpretation report, and associates the identification information of the limited subsequent inspection equipment used for the subsequent inspection with the inspection data as related information. It memorize | stores in the said memory | storage part. Furthermore, when the management unit receives a request for transmitting the inspection data from the limited subsequent inspection device, the management unit searches the inspection data with reference to the related information, and transmits the search result to the subsequent inspection device. you.

Timing chart of inspection data management system. The figure which shows the data structure of test | inspection data. The timing chart of the inspection data management system concerning a 2nd embodiment. The timing chart of the inspection data management system concerning a 3rd embodiment. The figure which shows the list structure of the address information of a reference image. The figure which shows the data structure of test | inspection data.

  A medical image acquired from the PACS for interpretation (a medical image obtained by imaging with a first examination device) is a reference image that is referred to in a subsequent examination when an instruction for a subsequent examination is required after interpretation.

  In order to improve the operability when specifying the reference image, the identification information of the subsequent inspection device used for the subsequent inspection may be associated with the reference image. Thereby, it becomes possible to extract the reference image from the medical image stored in the PACS using the identification information as a search key.

  Whether or not the medical image taken by the advance inspection device and stored in the PACS becomes the reference image is determined by whether or not there is an instruction for the subsequent inspection after the interpretation, so the timing of the association is After instructions.

  As an example of the association means, identification information may be attached to a medical image stored in an examination data storage management device (PACS). A medical image to which identification information is attached becomes a reference image. That is, in response to an instruction for subsequent inspection, identification information of the subsequent inspection apparatus may be associated with the reference image.

  In order to prevent the reference image search requests from being concentrated and prevent the transfer of the reference image from being delayed, it is sufficient to make a reference image search request before inquiring the reservation inspection information. May be performed as needed instead of periodically.
