Abstract
An image processing apparatus includes an image data acquisition unit, a development generating unit and a display unit. The image data acquisition unit acquires slice image data with regard to a heart of an object. The development generating unit obtains blood flow perfusion information with regard to a myocardial thickness direction based on the slice image data and generates development data according to a desired development format for displaying the blood flow perfusion information. The display unit displays the development data.
Claims23
An image processing apparatus comprising:
- an image data acquisition unit configured to acquire slice image data for different cross-sectional wall portions of a heart of an object;
- a development generating unit configured
- (a) to obtain blood flow perfusion data with respect to plural points within each of plural myocardial wall regions that are divided both radially across a myocardial thickness direction and circumferentially along the myocardial wall cross-section within each said cross-sectional wall portion based on the slice image data, and
- (b) based on the blood flow perfusion data, to generate development display data according to a predetermined bulls-eye development format wherein each cross-sectional myocardial wall region is divided both radially across a myocardial wall thickness direction and circumferentially along the myocardial wall cross-section within each cross-sectional wall portion to present at least two predetermined concentric circumferentially extending sets of radially-divided myocardial wall regions, and wherein the whole interior of each divided wall region is displayed with its own assigned visually perceptible display form based on the obtained blood flow perfusion data for said plural points therewithin such that all points within a divided wall region have the same visually perceived value;
- and
- a display unit configured to display the development display data.
