## Abstract

The medical image display apparatus according to any of embodiments includes processing circuitry. The processing circuitry is configured to determine whether a mouse cursor is superimposed on a display range of interpretation-target medical image data in a display screen of a display or not. Further, the processing circuitry is configured to display, when the mouse cursor is determined to be superimposed on the display range, at least one choice of comparative medical image data corresponding to interpretation-target medical image data specified by the position of a mouse cursor in an interpretation adjacent region where the specified interpretation-target medical image data is not superimposed and is adjacent to the specified interpretation-target medical image data.

## Claims

### Claim 1

A medical image display apparatus comprising:
processing circuitry configured to
determine whether a mouse cursor is superimposed on a display range of interpretation-target medical image data in a display screen of a display or not,
display, when the mouse cursor is determined to be superimposed on the display range, both of the interpretation-target medical image data and at least one choice of comparative medical image data corresponding to interpretation-target medical image data, specified by a position of a mouse cursor, arranged in choices of display layout in a pop-up menu to be shown in an interpretation adjacent region where the specified interpretation-target medical image data is not superimposed and is adjacent to the specified interpretation-target medical image data,
determine a display layout as selected via the mouse cursor among choices presented in the pop-up menu, and
determine a choice of comparative medical image data arranged in the determined display layout as the comparative medical image data for comparison.

### Claim 2 (depends on 1)

The medical image display apparatus according to claim 1, wherein the processing circuitry is configured to
initially display at least one choice of display layout having higher priority among choices presented in a pull-down menu, and
supplementarily display at least one choice of display layout having lower priority among choices presented in the pull-down menu by using an extended function.

### Claim 3

A medical image display system comprising:
a medical image display apparatus; and
a medical image management apparatus, wherein
the medical image display apparatus and the medical image management apparatus are interconnected via a network and configured to communicate with each other, and
the medical image display apparatus comprises processing circuitry configured to
acquire medical image data from the medical image management apparatus,
determine whether a mouse cursor is superimposed on a display range of interpretation-target medical image data in a display screen of a display or not,
display, when the mouse cursor is determined to be superimposed on the display range, both of the interpretation-target medical image data and at least one choice of comparative medical image data corresponding to interpretation-target medical image data, specified by a position of a mouse cursor, arranged in choices of display layout in a pop-up menu to be shown in an interpretation adjacent region where the specified interpretation-target medical image data is not superimposed and is adjacent to the specified interpretation-target medical image data,
determine a display layout as selected via the mouse cursor among choices presented in the pop-up menu, and
determine a choice of comparative medical image data arranged in the determined display layout as the comparative medical image data for comparison.

### Claim 4

A medical image display method comprising:
determining, by processing circuitry, whether a mouse cursor is superimposed on a display range of interpretation-target medical image data in a display screen of a display or not;
displaying, by the processing circuitry, when the mouse cursor is determined to be superimposed on the display range, both of the interpretation-target medical image data and at least one choice of comparative medical image data corresponding to interpretation-target medical image data, specified by a position of a mouse cursor, arranged in choices of display layout in a pop-up menu to be shown in an interpretation adjacent region where the specified interpretation-target medical image data is not superimposed and is adjacent to the specified interpretation-target medical image data;
determining, by the processing circuitry, a display layout as selected via the mouse cursor among choices presented in the pop-up menu; and
determining, by the processing circuitry, a choice of comparative medical image data arranged in the determined display layout as the comparative medical image data for comparison.
