Abstract

PURPOSE:To display an image to be used for film photographing or image reading on the screen of one display device and a reconstituted image and to improve working efficiency or system using efficiency by providing the image diagnostic device with a means for displaying a reconstituted image on another prescribed part without changing the display of a certain prescribed part on the screen. CONSTITUTION:A target is scanning by a scanner 2, the reconstitution of the scanned image is computed by a remote controller 3 and the reconstituted image is displayed on a main screen and photographed on a film. Simultaneously with film photographing, scanning is executed, reconstitution operation is execut ed and the reconstituted image is displayed on an auxiliary screen. Thereafter, the similar sequence is repeated. Since the succeeding scanning can be executed in parallel with the film photographing of the preceding reconstituted image and the reconstituted image can be checked, the using efficiency of the system can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to an image diagnostic apparatus, and more specifically, to an image diagnostic apparatus that allows a reconstructed image to be confirmed even during film shooting or image interpretation. Regarding equipment.

[Prior Art] In an example of a conventional image diagnostic apparatus, a scanning device obtains raw data from a diagnosis target (a in FIG. 5), and an image reconstruction device (recon device) performs reconstruction calculations to reconstruct the data. An image is generated (b) in FIG. 5, and this reconstructed image is stored in the storage device and displayed on the main part (referred to as the main screen) of the screen of the display device by the image display device (c in FIG. 5). At the same time, the image display device displays a reference image or the like on a part of the screen (referred to as an auxiliary screen) (W in FIG. 5).

FIG. 6 shows this screen, in which a reconstructed image 24 is displayed on the main screen 21 and a reference image 25 is displayed on the auxiliary screen 23.

The reconstructed image is confirmed on this main screen 21 (confirming whether the intended part was scanned correctly or whether the diagnostic target did not move, etc.), and a film is photographed (d in FIG. 5). The auxiliary screen 23 is not captured on film.

From scanning (Fig. 5 a) to film shooting (Fig. 5 d)
), the same cycle starts again (
Repeat steps from e in Fig. 5 to h in Fig. 5).

Diagnosis is performed by interpreting images on film or by displaying and interpreting images stored in a storage device on a screen.

In another example of a conventional image diagnostic apparatus, film photography is not performed, but scanning and reconstructed image generation are performed alternately and continuously, and a large number of reconstructed images are stored in a storage device. Then, later, the reconstructed images are sequentially displayed on the screen and film photography is performed.

[Problems to be Solved by the Invention] With conventional image diagnostic apparatuses, it is necessary to check the reconstructed image while shooting film or displaying one image on the screen for interpretation. There is a problem in that film shooting and interpretation of one image must be stopped.

Therefore, an image diagnostic apparatus has been proposed that is equipped with two image display devices and a display device, one of which displays images for film shooting and interpretation, and the other of which displays reconstructed images. A new problem arises in that the device becomes larger and more expensive.

Therefore, an object of the present invention is to display images for film shooting, image interpretation, etc. on the screen of a single display device, and to also display reconstructed images for confirmation without changing the display. The object of the present invention is to provide an image diagnostic apparatus that provides the following features.

[Means for Solving the Problems] An image diagnostic apparatus of the present invention is an image diagnostic apparatus that reconstructs an image from raw data obtained from a diagnosis target and displays it on a screen, and the image diagnosis apparatus changes the display of a predetermined portion of the screen. The structural feature is that a means for displaying the reconstructed image is provided in a predetermined part other than the original part.

[Operation] In the image diagnostic apparatus of the present invention, the screen is divided into two areas, and the reconstructed image is displayed in the other area without changing the display of one area.

Therefore, by displaying an image for film photography, image interpretation, etc. in an area that will not be changed, it becomes possible to check the reconstructed image without interfering with film photography, image interpretation, etc.

[Embodiments] The present invention will be explained in more detail below based on embodiments shown in the drawings. Note that this invention is not limited to this.

FIG. 2 is a block diagram of an image diagnostic apparatus 1 according to an embodiment of the present invention.

The scanning device 2 is, for example, an X-ray CT scanner, and obtains raw data from a diagnostic target (patient).

The recon device 3 performs a reconstruction operation on the raw data obtained by the scanning device 2 and generates a reconstructed image.

The data of the generated reconstructed image is stored in the reconstructed image data memory 4. It is also stored in the magnetic disk device 5.

When the image display device 6 receives an instruction for manual image recall J from the instruction manual device 9, it displays a list of images stored in the magnetic disk device 5 on the display 8, and displays the image selected by the operator from among the images. is read from the magnetic disk 5 to the image memory 7 and displayed on the main screen of the display 8.

Furthermore, when the image display device 6 receives an instruction to “auto view (single)” from the instruction manual device 9, the reconstructed image data memory 6 receives a notification from the recon device 3 that the image reconstruction operation has been completed. The reconstructed image data is transferred to the image memory 7 and displayed on the main screen of the display 8.

Further, the image display device 6 operates according to the flowchart shown in FIG. 1 when an instruction for "auto view (display in display)" is received from the instruction input device 9.

First, when the reconfiguration calculation is completed, the recon device 3 transmits an image display request to the image display device 6 using the communication function. This transmission content includes the address of the reconstructed image data memory 4 in which the reconstructed image data is stored and the matrix size of the reconstructed image data.

Upon receiving this communication, the image display device 6 performs step S1.
, it is determined whether the display is possible or not. If display is possible, proceed to step S2; if display is not possible, proceed to step S
Proceed to step 6.

In step S2, it is checked whether or not there is an instruction input from the instruction input device 9 to "display in display off". If the display is off, the process advances to step S6; otherwise, the process advances to step S3. This "display in display off" instruction turns off the display of the reconstructed image on the auxiliary screen.

In step S3, the reconstructed image data is transferred from the reconstructed image data memory 4 to the image memory 7.

In step S4, the reconstructed image is reduced to the size of the auxiliary screen.

In step S5, the reduced reconstructed image is displayed on the auxiliary screen of the display 8.

In step S6, the image display device 6 notifies the recon device 3 of permission to release the reconstructed image data memory 4. This allows the recon device 3 to generate the next reconstructed image and store it in the reconstructed image data memory 4.

FIG. 3 shows an example of a screen displayed on the display 8 by the above-mentioned "auto view (display in display)" operation.

The main screen 21 displays an image 2 read out from the magnetic disk 5.
2 is displayed. A reduced image 24 of the reconstructed image generated by the recon device 3 is displayed on the auxiliary screen 23.

The multi-format camera 10 photographs the main screen 21 on film. Film photography is not performed on the auxiliary screen 23.

Therefore, the reconstructed image generated by the recon device 3 can be checked without interfering with film photography of the image 22 read from the magnetic disk 5. Also, reading images,
The reconstructed image can be checked without interfering with the selection of images to be displayed on the main screen 21.

FIG. 4 shows an example of the operation sequence of the image diagnostic apparatus 1, in which the scanning device 2 performs scanning (a in FIG. 4), and the recon device 3 performs reconstruction calculations (in FIG. 4). b) Display the reconstructed image on the main screen 21.
), then shoot on film (d in Figure 4).

At the same time as film shooting (d in Fig. 4), scanning is performed (e in Fig. 4), reconstruction calculation is performed (f in Fig. 4), and the reconstructed image is displayed on the auxiliary screen (Fig. 4). g).

The same sequence is repeated thereafter.

Therefore, the next scan can be performed in parallel with film photography of the previous reconstructed image, and the reconstructed image can be checked, thereby improving the usage efficiency of the system.

Another example is one in which the present invention is applied to an MR apparatus.

[Effects of the Invention] According to the image diagnostic apparatus of the present invention, images for film shooting, image interpretation, etc. are displayed on the screen of one display unit, as well as reconstructed images, so that film shooting, image interpretation, etc. Now you can check the reconstructed image without canceling the process.

Therefore, work efficiency and system usage efficiency are improved.

In addition, the structure is smaller and cheaper.
