Description

Embodiments of the present invention relate to an ultrasonic diagnostic apparatus, a medical image processing apparatus, and a medical image processing program.

Multiplane probes may be used in examinations with ultrasonic diagnostic equipment. A multi-plane probe is an ultrasonic probe that can simultaneously collect image data of a plurality of cross sections by an operator such as a doctor or a technician.

An example of a test for which a multiplane probe is desired to be applied is a stress echo test. The stress echo examination is an examination in which an image before applying a load to a subject and an image after applying a load are collected and both images are compared and analyzed. Examples of the load include exercises such as stepping up and down, drug administration, and the like.

An example of an image collection site is the heart. The cardiac function of the subject is evaluated by comparing and analyzing the images of the heart before and after loading. When collecting images before and after loading and before and after the heart rate changes, he wants to collect image data of multiple cross sections in a short time by collecting image data of multiple cross sections in parallel with a multiplane probe. There is a request. In addition, usually, along with the collection of image data, image data of a plurality of cross sections is sequentially displayed on the monitor. Thereby, the operator can operate the ultrasonic diagnostic apparatus and the ultrasonic probe while visually recognizing whether the image data of the desired cross section can be collected.

At this time, on the display, image data of a plurality of cross sections are displayed side by side in one display window. For example, when the number of cross sections is two (biplane), two cross-section image data collected in parallel (at the same time phase) are displayed side by side in one display window. Then, the collected image data of a plurality of cross sections is stored as one set for each time phase collected in parallel.

Image data of a plurality of cross sections is usually compared and analyzed by an image processing device such as a workstation. A general-purpose workstation that is not equipped with dedicated application software that supports multi-plane image data is configured to process image data in a format that displays one cross-sectional image data in one display window. ing. Therefore, it has been difficult to compare and analyze a set of image data (image data by a multiplane) that displays a plurality of cross-sectional image data in one display window as it is. For example, when an operator visually recognizes a plurality of cross sections included in one set of collected image data, individually distinguishes the cross-section image areas by manual operation, and then performs comparative analysis, the work procedure is time-consuming. It's complicated.

The multi-section image generation circuit 112 is a processor that generates a multi-section image data showing a plurality of cross sections of a subject based on an echo signal from the transmission / reception circuit 111. The data format of the plurality of cross-sectional image data may be ultrasonic raster data (hereinafter referred to as RAW data) or pixel value data obtained by converting RAW data into pixel values. Further, the plurality of cross-sectional image data may be either two-dimensional image data or three-dimensional image data. The control program for converting the echo signal into the plurality of cross-sectional image data may be appropriately set based on a general multiplane scan program.

Further, a plurality of components in FIG. 1 may be integrated into one processor to realize the function.

The multi-section image generation circuit 112 attaches cross-section number information indicating the number of indicated cross-sections and position information indicating the position of each indicated cross-section to the multi-section image data. For example, in the case of a biplane image, the number of cross sections indicated by the number of cross sections information is "2", and the position information individually indicates the cross section positions of the two cross sections. The position information may be cross-section direction information indicating the direction of each cross-section (relative angle with the ultrasonic probe 100), or may be coordinate information indicating each cross-section in a three-dimensional coordinate system. In other words, the plurality of cross-section image generation circuit 112 may generate the plurality of cross-section image data while attaching the cross-section direction information as the position information, or may generate the plurality of cross-section image data while attaching the coordinate information as the position information. good. Further, the plurality of cross-section image generation circuit 112 attaches the position information to the plurality of cross-section image data while associating each cross-section shown in the position information with the corresponding cross-section image data. As a result, each cross-sectional image data in the plurality of cross-sectional image data and the corresponding position information are associated with each other.

In addition, information such as the collection date and time, the time, and the device ID is also attached. Information incidental to the plurality of cross-sectional image data such as position information, collection date and time, and device ID is referred to as incidental information here. The incidental information may be included in the header area of the plurality of cross-sectional image data, or may be included in the source area.

At this time, the display control circuit 12 displays a plurality of cross-sectional images collected simultaneously in parallel in one display window on the display 3 in the same manner as a general multiplane image. For example, in the case of a biplane scan, two cross-sectional images collected in parallel are displayed side by side in one display window.

The storage circuit 13 has a memory area and is composed of storage devices such as ROM and RAM. The database structure of the memory area may be set as appropriate. The storage circuit 13 is an example of a storage unit within the scope of claims.

Further, the multi-section image generation circuit 112 outputs the multi-section image data to the individual image generation circuit 14 when receiving a predetermined setting instruction via the input circuit 2. The setting instruction is an operation instruction via the input circuit 2, and an input operation to a predetermined button switch or the like is set in advance.

Then, the system control circuit 16 controls the multiple cross-sectional image generation circuit 112 to output the selected multiple cross-sectional image data to the individual image generation circuit 14.

The individual image generation circuit 14 is a processor that generates individual image data for each cross section based on the position information for each cross section related to the plurality of cross-section image data.

In addition, the individual image generation circuit 14 may generate individual image data from the plurality of cross-section image data each time the plurality of cross-section image data is sequentially generated (for example, for each frame rate). In this case, the individual image generation circuit 14 sequentially generates the individual image data by performing the above processing each time the plurality of cross-sectional image data is sequentially generated, and sequentially outputs the individual image data to the storage circuit 13 and the communication interface 15.

Further, the individual image generation circuit 14 may be configured to generate individual image data when a predetermined setting instruction is received via the input circuit 2. Thereby, the operator can operate the ultrasonic diagnostic apparatus while switching between the case where the individual image data is desired to be generated and the case where the individual image data does not need to be generated.

The storage circuit 13 stores the individual image data Da'and the individual image data Db'. The communication interface 15 is communicably connected to the external server 200 via the network N. The communication interface 15 outputs the individual image data Da'and the individual image data Db'to the server 200. Alternatively, the plurality of cross-sectional image data Dab may be included and output. The communication protocol in the communication interface 15, the network N, and the server 200 and the database structure in the server 200 may be appropriately defined. For example, the individual image data Da'and the individual image data Db' stored in the server 200 may be used.
