Abstract

The present invention discloses a medical image fusion apparatus and method. The medical image fusion apparatus comprises: a display unit configured to display a plurality of medical images in layers in one window on a screen, wherein the arrangement direction of the plurality of medical images is different from the extension direction of the plane on which each medical image exists; an operation detection unit configured to detect an operation of selecting the medical images to be fused from the plurality of medical images; and a fused image generation unit configured to generate a fused image of the medical images to be fused according to the selection operation, wherein the display unit is further configured to display the fused image in a predetermined region in the window.

First claim

What is claimed is:

1. A medical image display apparatus, comprising:
processing circuitry configured to
cause a first display region on a display to display a plurality of modified medical images that are generated by reducing a length, in a predetermined direction of the first display region, of a plurality of medical images of substantially an identical region of a subject, wherein partial areas of the modified medical images overlap with each other in such a manner as to arrange the modified medical images in the predetermined direction;
detect a selection operation to select at least two of the displayed modified medical images to be fused, from the plurality of modified medical images; and
generate a fused image from the at least two medical images corresponding to the at least two selected modified medical images selected by the selection operation,

wherein the processing circuitry is further configured to cause the fused image to be displayed in a second display region on the display, which is different from the first display region on the display.

2. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to cause the display to display the fused image in the first display region, wherein a partial area of the fused image is overlapped with at least one of the plurality of modified medical images.

3. The medical image display apparatus according to claim 2 , wherein the processing circuitry is further configured to cause the display to display the fused image in the foreground in the first display region.

4. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to cause the display to display the fused image and the modified medial images corresponding to the medical images from which the fused image is generated, wherein both of the fused image and the medical images are each displayed with an identical identifier.

5. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to detect a cancelling operation to cancel a display of the fused image in the second display region, and cancel the display of the fused image when the cancelling operation is detected.

6. The medical image display apparatus according to claim 5 , wherein the processing circuitry is further configured to detect a drag-and-drop operation to move the fused image out of the second display region as the cancelling operation.

7. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect a layer interval changing operation to change an interval between two layers of a plurality of layers of the modified medical images displayed in the first display region, and
cause the display to display in the first display region the two layers of the modified medical images at the interval changed by the layer interval changing operation when the layer interval changing operation is detected.

8. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect an order changing operation to change an order of the plurality of modified medical images displayed in the first display region, and
cause the display to display in the first display region the plurality of modified medical images in the order when the order changing operation is detected.

9. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect a layer rotation operation to rotate layers of the plurality of the modified medical images displayed in the first display region, and
cause the display to display in the first display region the layers of the plurality of the modified medical images rotated by the layer rotation operation.

10. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect an arrangement direction rotation operation to rotate an arrangement direction of the plurality of the modified medical images displayed in the first display region, and
cause the display to display in the first display region the plurality of the modified medical images of which the arrangement direction is rotated by the arrangement direction rotation operation.

11. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect a display changing operation regarding a modified medical image of the plurality of modified medical images, and
cause the display to
hide the modified medical image when the modified medical image is displayed in the first display region when the display changing operation is detected, and
display the modified medical image when the modified medical image is not displayed in the first display region when the display changing operation is detected.

12. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect any one of a first display operation to display the first display region on a full-window of the screen, a second display operation to display the second display region on the full-window, and a third display operation to display the first display region and the second display region on the full-window, and
cause the display to display the first display region on the full-window when the first display operation is detected, display the second display region on the full-window when the second display operation is detected, and display the first display region and the second display region on the full-window when the third display operation is detected.

13. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect a display parameter changing operation to change a display parameter of a medical image of the plurality of the medical images, the display parameter including at least one of brightness, contrast, transparency, and display region size of the medical images to be fused, and
re-generate the fused image by using the medical image of which the display parameter is changed.

14. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to
detect a selection operation to generate at least two different fused images,
generate the at least two different fused images when the selection operation is detected, and
cause the display to display the generated at least two different fused images on different display regions, respectively.

15. A medical image display method executed by a medical image display apparatus, the method comprising:
causing a first display region on a display to display a plurality of modified medical images that are generated by reducing a length, in a predetermined direction of the first display region, of a plurality of medical images of substantially an identical region of a subject, wherein partial areas of the modified medical images overlap with each other in such a manner as to arrange the plurality of modified medical images in the predetermined direction;
detecting, using the medical image display apparatus, a selection operation to select the at least two of the displayed modified medical images to be fused, from the plurality of modified medical images; and
generating, using the medical image display apparatus, a fused image from the at least two medical images corresponding to the at least two selected modified medical images selected by the sele
