Abstract
A storage unit stores volume data including a blood vessel region. An extracting unit extracts the blood vessel region from the volume data. A specifying unit specifies a position of a region of interest in the blood vessel region and a deflection direction of a blood vessel region included in the region of interest. A determining unit determines a viewing position and a viewing direction based on the position of the region of interest and the deflection direction. A generating unit generates image data concerning the viewing position and the viewing direction based on the volume data. A display unit displays an image represented by the image data.
Claims18
An image processing apparatus comprising:
- a storage memory configured to store volume data including a blood vessel region;
- a display;
- and
- processing circuitry configured to:
- extract the blood vessel region from the volume data stored in the storage memory;
- allocate to each blood vessel branch included in the extracted blood vessel region a label indicating a class name of the blood vessel branch;
- specify a position of a region of interest in the extracted blood vessel region and a deflection direction of a blood vessel region included in the region of interest based upon a deflection parameter, indicating the degree of deflection of a blood vessel wall included in the extracted blood vessel region;
- determine a viewing direction so that the viewing direction is perpendicular to the deflection direction;
- generate image data concerning the viewing direction based on the volume data stored in the storage memory;
- display an image represented by the image data on the display;
- determine whether or not the label should be displayed by comparing a length ratio between the blood vessel region included in the image displayed on the display and the blood vessel region in the volume data with a predetermined value;
- and
- arrange, in case where the label is determined to be displayed, the label at the image displayed on the display.
An image processing method carried out by processing circuitry, the method comprising:
- extracting a blood vessel region from volume data stored in a storage device;
- allocating to each blood vessel branch included in the extracted blood vessel region a label indicating a class name of the blood vessel branch;
- specifying a position of a region of interest in the extracted blood vessel region and a deflection direction of a blood vessel region included in the region of interest based upon a deflection parameter, indicating the degree of deflection of a blood vessel wall included in the extracted blood vessel region;
- determining a viewing direction so that the viewing direction is perpendicular to the deflection direction;
- generating image data concerning the viewing direction based on the volume data stored in the storage memory;
- displaying an image represented by the image data on a display;
- determining whether or not the label should be displayed by comparing a length ratio between the blood vessel region included in the image displayed on the display and the blood vessel region in the volume data with a predetermined value;
- and
- arranging, in case where the label is determined to be displayed, the label at the image displayed on the display.
