Abstract

A three-dimensional medical image is obtained, and displayed on a display screen. An input position by a user on the display screen and an input operation by the user are received. If the received input position is located in a center region of the display screen, rotation processing is performed on the three-dimensional medical image based on the received input operation. If the received input position is located in a region other than the center region, region specification processing is performed on the displayed three-dimensional medical image based on the received input operation. The region specification processing specifies a closed curve on the display screen based on the received input operation, and deletes a part of the three-dimensional medical image, and the part being an inside or an outside of a cylinder extending from the specified closed curve toward the depth direction of the display screen.

Claims

1. An image processing apparatus comprising:

an image obtainment unit that obtains a three-dimensional medical image;

a display control unit that displays the obtained three-dimensional medical image on a display screen;

an input unit including a pointing device for receiving an input position by a user on the display screen, and an input operation by the user; and

an image processing unit that performs rotation processing on the displayed three-dimensional medical image based on the received input operation when the received input position is located in a center region of the display screen, and that performs region specification processing on the displayed three-dimensional medical image based on the received input operation when the received input position is located in a region other than the center region of the display screen,

wherein the region specification processing specifies a closed curve on the display screen based on the received input operation, and deletes a part of the three-dimensional medical image, and the part being an inside or an outside of a cylinder extending from the specified closed curve toward the depth direction of the display screen.

2. An image processing apparatus, as defined in claim 1, wherein the area of the center region is less than or equal to 1/9 of the area of the display screen.

3. An image processing apparatus, as defined in claim 1, wherein the display control unit displays an index, the size of which is smaller than the size of the center region, in the center region.

4. An image processing apparatus, as defined in claim 1, wherein the region specification processing specifies, based on the received input operation, the closed curve on the display screen also by using an outer edge of the display screen, and deletes a part of the three-dimensional medical image, and the part being an inside of a cylinder extending from the specified closed curve toward the depth direction of the display screen.

5. An image processing apparatus, as defined in claim 1, wherein the area of the center region is greater than or equal to 1/300 of the area of the display screen and less than or equal to 1/20 of the area of the display screen.

6. An image processing apparatus, as defined in claim 1, wherein the three-dimensional medical image includes a plurality of organs.

7. An image processing method comprising:

an image obtainment step for obtaining a three-dimensional medical image;

a display control step for displaying the obtained three-dimensional medical image on a display screen;

an input step for receiving an input position by a user on the display screen, and an input operation by the user; and

an image processing step for performing rotation processing on the displayed three-dimensional medical image based on the received input operation when the received input position is located in a center region of the display screen, and performing region specification processing on the displayed three-dimensional medical image based on the received input operation when the received input position is located in a region other than the center region of the display screen,

wherein the region specification processing specifies a closed curve on the display screen based on the received input operation, and deletes a part of the three-dimensional medical image, and the part being an inside or an outside of a cylinder extending from the specified closed curve toward the depth direction of the display screen.

8. A non-transitory computer-readable recording medium storing therein an image processing program for causing a computer to function as:

an image obtainment unit that obtains a three-dimensional medical image;

a display control unit that displays the obtained three-dimensional medical image on a display screen;

an input unit including a pointing device for receiving an input position by a user on the display screen, and an input operation by the user; and

an image processing unit that performs rotation processing on the displayed three-dimensional medical image based on the received input operation when the received input position is located in a center region of the display screen, and that performs region specification processing on the displayed three-dimensional medical image based on the received input operation when the received input position is located in a region other than the center region of the display screen,

wherein the region specification processing specifies a closed curve on the display screen based on the received input operation, and deletes a part of the three-dimensional medical image, and the part being an inside or an outside of a cylinder extending from the specified closed curve toward the depth direction of the display screen.
