Description

  The present invention relates to a technique for improving the efficiency of registration processing in an image management server that manages medical images.

  In recent years, systemization in hospitals has progressed, and various systems have been operating in hospitals. For example, an image management system (PACS) or a radiation information system (RIS) is connected to a network, and a computer terminal on the network is used to communicate with these medical image storage devices and radiation information systems to obtain medical images and examination status information. Send and receive inspection order information.

  The image management system is a system for managing medical images transmitted from a modality for creating medical images, and is a system for storing medical images so that the created medical images can be displayed on a client terminal via a network. .

  In this image management system, with the recent development of in-hospital systems, medical images are becoming filmless, and medical images that must be managed by the image management system are rapidly increasing. First, the image management system makes it possible to use medical images by registering a huge number of medical images. The registration process is to finally store the medical image and write the medical image information in the database. By this registration process, the medical image can be transmitted from the image management system to the terminal. Interpretation can be used.

  However, the number of medical images that a modality or the like attempts to create or transfer may reach tens of thousands per image capture, and enormous load is required to register a medical image requested to be registered by a plurality of modalities. Currently, medical images waiting for registration processing are in a queue. The accumulated queues include medical images having importance and ready-to-use properties, and in particular, these need to be registered and used quickly.

  Thus, a technique has been proposed in which a plurality of image management servers for performing registration processing are prepared, and load distribution is performed by distributing the registration processing to the plurality of image management servers (see, for example, Patent Document 1). This technique increases the processing speed of registration processing by performing registration processing with a plurality of image management servers.

This table is for setting the priority of the registration process of the medical image from the viewpoint of the slice thickness attribute of the medical image. For example, in FIG. 6E, “5” is stored in the priority 30 corresponding to the case where the slice thickness information 29 of the medical image is “0.5 mm or less”.

  In addition, as the correspondence table 133, a table in which combinations of various transfer destinations, designated date and time, and priorities shown in (f) of FIG. This table is a table for setting the priority when the current date and time match the specified date and time for the process of transferring a medical image having attribute information that matches the transfer condition to a predetermined transfer destination. In the image management server 100, a medical image accompanying predetermined transmission source information and examination date information is loaded in a transfer queue in order to perform a process of transferring to a predetermined transfer destination. That is, a medical image having attribute information of a predetermined transmission source and attribute information of a predetermined examination date / time is given a transfer destination attribute, and the transfer destination attribute assigned to the medical image is given by this table. Priorities are set for processing according to information. For example, FIG. 6F corresponds to the case where the transfer destination information 31 of the medical image is “3DWS” and the current date and time has arrived at “Tuesday, 13: 00 to 20:00” of the designated date information 32. Thus, “8” is stored in the priority 33.

  When the correspondence table 133 is prepared corresponding to a plurality of types of attributes, each correspondence table 133 may be weighted. In FIGS. 6A to 6F, the weights 34 and 35 are assigned to each correspondence table 133. , ... are stored. In this case, as will be described later, the value obtained by multiplying the priority by the weight becomes the final priority, and the various correspondence tables 133 can be given superiority or inferiority. The correspondence table 133 can be added / changed by an operation input by the apparatus operator using the input unit 170, and attribute information stored in the correspondence table 133 can be added / changed. The degree and weight can be changed.

  Further, in this embodiment, the priority corresponding to the emergency patient ID is stored in the patient attribute correspondence table 133 shown in FIG. 6D, and this priority is set to be much higher than others. . For example, “99999999” as the patient ID 40 at the top of the table shown in FIG. 6D and the patient ID 41 without the value at the next level are emergency patient IDs, and the corresponding priority 42 is set to “100”. Yes. It functions as an emergency flag by attaching an emergency patient ID to an emergency patient. When an emergency flag is attached to a medical image as attribute information, an emergency attribute correspondence table 133 may be provided.

  The priority acquisition unit 132 as the setting unit of the present invention uses the correspondence table 133 to set the priority for the registration process of each medical image. The received data is read from the medical image storage unit 120, the attribute information is acquired, and the current date and time are acquired. The attribute correspondence table 133 corresponding to the acquired attribute information is read, an item matching the attribute information is searched, and the priority stored in the corresponding item is acquired. Also, the correspondence table 133 for setting the priority of the transfer process is read, and the item that matches the attribute information and the current date and time is searched. When the corresponding item is detected, the priority stored in the item is acquired. To do. If a weight is set in the correspondence table 133, the weight is acquired and weighted by multiplying the priority by the weight.

  When a plurality of correspondence tables 133 are prepared in accordance with a plurality of types of attributes, a plurality of attribute information is acquired from the received data, and the correspondence table 133 corresponding to the acquired attribute information is referred to and the corresponding attribute information is associated. Get priority. Furthermore, a plurality of acquired priorities are compared and the highest priority is adopted.

  The processing order determination unit 131 serving as an instruction unit of the present invention determines the next registration process to be performed from the priority of the registration process set for each medical image, and instructs the registration processing unit 140 to perform the next registration process. The processing order determination unit 131 compares priorities set for registration processing of medical images loaded in the queue, and determines the registration processing with the highest priority as the next registration processing. If there are a plurality of same priorities, the job with the earlier waiting order is determined as the registration process to be performed next. The processing order determining unit 131 compares priorities without distinguishing between the transfer processing queue and the registration processing queue, and determines the queue with the highest priority as the next registration processing.

  FIG. 7 is a display screen in which a registration process queue is displayed on the display means 160. On the registration processing queue display screen shown in FIG. 7, the registration processing jobs for each medical image are loaded in the queue and displayed with a job number. The attribute information of the medical image corresponding to the job such as transmission source information 51, transmission date / time information 52, examination date / time information 53, patient ID 54, and slice thickness information 55 is displayed in pairs. The job is displayed with a queue status 56 indicating the stage of the registration process, and the priority 57 set by the priority acquisition unit 132 for each job is displayed. When the weighting process is performed in the priority setting process, the priority 57 displays the final priority obtained by the weighting. The queue status indicates details of processing performed during the registration processing. In the case of transfer processing, the data is loaded in a transfer processing queue (not shown). If a plurality of transfer destinations are set, they are stacked for each transfer destination.

  For example, in the case of the queue illustrated in FIG. 7, the registration processing target of “job No. 3022” is “3D workstation” in the transmission source information 51, “2005/3/3” in the transmission date information 52, and the inspection date information 53 is a medical image having “2005/3/1”, patient ID 54 “000004001”, and slice thickness information 55 “3.0”, “write” in the queue status 56, and priority 57 for the registration process.

A command to be transmitted to the image management server 100 is created, medical images to be processed are read from the external storage unit 100c, and these commands and medical images are transmitted to the 3D workstation 500 (S24).

  When the queue status is the medical image compression processing stage (S25, Yes), the medical image to be compressed is read from the external storage unit 100c, and data compression processing is performed on the read medical image (S26). Then, an image storage command is created, the medical image subjected to data compression processing is transmitted to one of the image storage devices 310, 320,... Together with the image storage command, and the medical image is written to the storage destination (S27). Simultaneously with writing to the storage destination, a record is newly created in which each attribute information of the written medical image is paired, and the image database is updated (S28).

  When the queue status is the medical image writing stage (S29, Yes), the medical image to be written is read from the external storage unit 100c, an image storage command is generated, and the compressed medical image generated by data compression processing is used. The image is transmitted to one of the image storage devices 310, 320,... Together with the image storage command, and the medical image is written in the storage destination (S27). Simultaneously with writing to the storage destination, a record is newly created in which each attribute information of the written medical image is paired, and the image database is updated (S28).

  When the queue status is the medical image transfer stage (S30, Yes), the medical image to be transferred is read from the external storage unit 100c and transferred to the transfer destination (S31). The operations from S21 to S32 are performed until the registration process is completed (No in S34), and the series of processes is terminated.

  As described above, the image management server 100 performs registration processing based on the priority assigned to the registration processing of medical images, and thus preferentially registers and uses medical images that are important or ready to use. enable.

  Next, the operation based on the configuration described above will be described using an example described in each drawing. For example, in the case of the received data shown in FIG. 5, the transmission source information is “3DWS”, the transmission date / time information is “2005/3/3”, the examination date / time information is “2005/3/1”, the patient ID is “000004001”, and the slice The thickness information is “3.0” mm.

  When the attribute information is acquired and the corresponding item in the correspondence table 133 shown in FIG. 6 is searched, the priority is “3” and the weight is “3” in the correspondence table of the transmission source attribute information shown in FIG. Therefore, the final priority “9” is acquired. In the acquired transmission date / time information, imaging date / time information, and slice thickness information, there are no items corresponding to (b), (c), and (e) in FIG. 6, and priority is not acquired. The final priority “20” is acquired from the correspondence table of the patient ID and the patient attribute shown in FIG. Comparing the acquired priorities, the highest priority “20” is set in the registration process of the medical image included in the received data shown in FIG.

  Next, in the registration processing queue shown in FIG. 7, “Job No. 3022” is waiting for registration processing of the medical image included in the received data shown in FIG. In the registration process queue illustrated in FIG. 7, the registration process of a medical image with a priority “20” has the highest priority, and is designated as the next registration process. Next, “Job No. 0001” and “Queue No. 3021” are instructed in descending order of priority. “Job No. 0002” and “Job No. 0003” have a priority of “9” and have the same priority, so that “Job No. 0002” with the earlier waiting order is instructed to register first. The

  In many cases, medical images have a difference in ready-to-use properties depending on the transmission source. For example, a two-dimensional medical image transmitted from the 3D workstation 500 is created as preparation for interpretation, and is often determined to be interpreted in the near future. When the priority is set corresponding to the transmission source information as in the image management server 100 of this embodiment, the registration process can be performed according to the ready-to-use medical image.

  Also, new medical images are often more immediately usable than medical images whose transmission date and examination date are left undisturbed, and they match the registration processing timing of medical images from the viewpoint of the interpretation doctor's interpretation schedule. Can be made.

  In addition, there is a difference in the immediate use of medical images depending on the patient, and in particular in the case of an emergency patient, it is necessary to make the immediate medical image available. From the patient's viewpoint, the registration process depends on the ready use of the medical image. it can.

  In addition, when priority is given to registration processing of medical images according to slice thickness, it is often more efficient that registration processing is more efficient when a two-dimensional medical image is first created for thin medical images, It is valid.

  In addition, when priority is given to processing for transferring a specific medical image to a specific transfer destination at a specific date and time, it is possible to match the registration timing of the medical image from the viewpoint of the interpretation schedule of the interpretation doctor.

  In the present embodiment, all the registration processing steps are processed by the image management server 100. However, for example, data compression can be performed by another server. The registration process schedule based on this may be synchronized. In addition, regarding reception of received data, reception may be divided for each transmission source to increase the usage rate of the processing unit 100a.
