It does not change. It is also possible to set an upper limit such as “10” for the number of tomographic images that are combined and displayed. In this case, when the upper limit number of tomographic images are combined and displayed. Even if an increase in the number of composites is input, the displayed tomographic image does not change.
- step S7 in the state where the tomographic image front / rear switching is selected by the input operation of the function selection switch 204 (step S7), the image display device 300 shown in FIG.
- the joystick 121 of the input operation device 100 is tilted back and forth to the first stage (steps S26 and S29)
- step S28 and S31 only one tomographic image displayed on the display unit 211 is switched back and forth.
- Steps S28 and S31 the index image is moved up and down by one level correspondingly (Steps S27 and S30).
- step S32 and S35 when the joystick 121 is moved back and forth to the second stage (steps S32 and S35), the displayed tomographic image is switched back and forth at a low speed (steps S34 and S37), and the index image is slowed down.
- step S38 and S41 When the joystick 121 is moved back and forth to the third stage (steps S38 and S41), the displayed tomographic image is switched back and forth at high speed (steps S40 and S43).
- the index image is moved up and down at high speed (steps S39 and S42).
- the display switching of the tomographic image as described above is executed for the combined tomographic image. Therefore, for example, when the number of combined images is n, consecutive n tomographic images are combined and displayed on the display unit 211.
- the number of tomographic images to be displayed can be reduced to 1 / n by combining and displaying a large number of consecutive tomographic images as described above.
- confirmation of a large number of tomographic images of series data can be facilitated.
- the tomographic images to be displayed are synthesized in succession of n pieces, and the tomographic images are not thinned out, so that oversight of necessary information can be prevented.
- the tomographic images are synthesized and displayed in succession of n pieces, so that the lesion display image Ii as described above is linearly displayed on the tomographic image Is as shown in FIG. It can be displayed on the screen and the discovery can be made easy.
- the speed and accuracy of confirmation of tomographic images can be freely adjusted. For this reason, for example, at a position where the possibility of the presence of a lesion is low, the number of combined tomographic images is increased.
- it is possible to improve the confirmation speed by improving the confirmation speed and reducing the number of synthesized tomographic images at a position where the possibility of the presence of a lesion is high.
- the point image Ii is found in the tomographic image Is as described above. It is also possible to increase the number of composites and check whether the display image H is a lesion.
- the number of combined tomographic images can be increased or decreased at a speed corresponding to a plurality of input operations to the input operation device 100, the number of combined tomographic images can be easily and freely adjusted.
- the composite number can be increased or decreased at low speed and high speed, and can be increased or decreased one by one, so that the desired composite number can be set quickly and easily.
- the displayed tomographic image can also be switched back and forth at a speed corresponding to a plurality of steps of input operation to the input operation device 100, display switching of the tomographic image can be performed easily and freely. This display switching can be performed at high speed and low speed all at once, so it is easy to quickly search and display the desired tomographic image.
- the increase / decrease in the number of combined tomographic images as described above and the front / rear switching of the displayed tomographic images are performed by one input operation device 100 by the switching setting of the function selection switch 204. Therefore, it is possible to simplify the structure of the image display device 300 and improve productivity.
- orthogonal image is generated by extracting and arranging linear portions at the same position from a large number of consecutive tomographic images, it is not necessary to prepare an orthogonal image corresponding to the series data. Orthogonal images accurately corresponding to series data can be acquired automatically.
- an orthogonal image is displayed in a small size on the lower right side of the tomographic image, and text data such as the name of the subject and the number of synthesized images are displayed above it. Is displayed on the display screen of the display unit 211. It does not occur.
- the present invention is not limited to the above-described embodiments, and various modifications are allowed without departing from the gist thereof.
- a force exemplifying that an orthogonal image is generated from a number of continuous slice images of series data. It is also possible to separately prepare orthogonal images corresponding to such series data.
- the force exemplifying that the number of combined tomographic images can be increased / decreased at high speed, low speed, one by one by the input operation device 100.
- Such increase / decrease speed can be set in various ways. For example, it is possible to increase / decrease at an infinitely variable speed by an analog input operation device (not shown).
- a small orthogonal image Iv is displayed below the right side of the combined large tomographic image Ism, and a small unsynthesized tomographic image I is displayed above it. It is also possible to do so.
- This unsynthesized tomographic image can be, for example, the first tomographic image or the tomographic image at the center of the synthesized tomographic image, which is then synthesized and synthesized with the tomographic image. It is possible to check images simultaneously.
- a force exemplifying that the combined number is displayed as text data on the display screen of the display unit 211 that displays the tomographic image.
- the interval at which the tomographic image is captured from the subject and the combined number It is also possible to calculate the layer thickness of the tomographic image synthesized by multiplying and to display this layer thickness as text data as shown in FIG. In this case, you can check not only the number of combined tomographic images to be displayed but also the layer thickness. Therefore, the convenience can be further improved.
- a plurality of tomographic images are overlapped.
- a plurality of tomographic images can be averaged.
- the series data of the tomographic image displayed on the image display device 100 is exemplified as being captured by the CT scanner 410.
- this is captured by an MRI apparatus (not shown) or the like. .
- each of these various means can be formed as unique hardware, and a part can be stored in the RAM 304 or the like as software and a part can be formed as nodeware.
