Abstract

A medical image display apparatus includes the following. A touch operating unit receives a touch input on a display screen of a display which displays a medical image. A display controller moves a movement operation element in response to the touch input to a region including the medical image except for the movement operation element displayed on the display screen.

First claim

What is claimed is:

1. A medical image display apparatus comprising:
a touch screen display configured to receive a touch input on a display screen which displays a medical image; and
a display controller configured to:
control the display screen to display a plurality of cursors;
after the plurality of cursors are displayed, and in response to a touch input at a touch position that is (i) in a region of the touch screen display including the medical image and (ii) spaced apart from the plurality of cursors displayed on the display screen, detect which one of the plurality of cursors on the display screen is closest to the touch position, and set the detected one of the plurality of cursors as a control target cursor; and
after setting the detected one of the plurality of cursors as the control target cursor, perform a movement operation on the control target cursor on the display screen in response to a sliding touch operation input to the touch screen display, to move the control target cursor while maintaining a relative distance between the touch position and the control target cursor which is spaced apart from the touch position.

2. The medical image display apparatus according to claim 1 , wherein the display controller is further configured to control the display screen to display a display element in addition to the plurality of cursors, the display element associating a position of the control target cursor with the touch position of the touch input.

3. The medical image display apparatus according to claim 1 , wherein the display controller is configured to control the display screen to begin display of a first one of the plurality of cursors in response to a predetermined operation.

4. The medical image display apparatus according to claim 1 , wherein the display controller is configured to control the display screen to simultaneously begin display of a number of the cursors to be used in a calculation of a feature amount of a measurement target in the medical image in response to a predetermined operation.

5. The medical image display apparatus according to claim 1 , wherein the display controller is further configured to:
in response to a touch input directly on one of the plurality of cursors, move said one of the plurality of cursors to a position where said one of the plurality of cursors is not hidden by an operation source of the touch input, and such that said one of the plurality of cursors is spaced apart from the touch position of the touch input.

6. The medical image display apparatus according to claim 5 , wherein the display controller is further configured to:
after moving said one of the plurality of cursors to the position where said one of the plurality of cursors is not hidden by the operation source of the touch operation, control movement of said one of the plurality of cursors in response to a sliding touch operation input to the touch screen display, to move said one of the plurality of cursors while maintaining a relative distance between the touch position and said one of the plurality of cursors spaced apart from the touch position.

7. The medical image display apparatus according to claim 1 , further comprising a calculator which calculates a feature amount of a measurement target of the medical image according to positions of the plurality of cursors.

8. The medical image display apparatus according to claim 1 , wherein the display controller is configured to:
control the display screen to display an operation button for beginning a measurement operation; and
in response to a user touch operation on the operation button, control the display screen to simultaneously display said plurality of cursors and a line connecting said plurality of cursors at temporary positions to be adjusted by a user.
