Abstract
An X-ray imaging apparatus is configured to acquire a plurality of pieces of slice image data from volume data, acquire a plurality of pieces of first processed image data by performing first processing, acquire a plurality of pieces of second processed image data by performing second processing, detect edges of the subject based on the acquired plurality of pieces of the second processed image data, and acquire edge image data including detected edges of the subject.
Claims10
An X-ray imaging apparatus comprising:
- an X-ray source;
- a detector configured to detect X-rays emitted from the X-ray source and passed through a subject;
- and
- an image processing unit configured to acquire three-dimensional volume data by reconstruction processing based on X-ray detection data from the detector,
- wherein the image processing unit is configured to
- acquire a plurality of pieces of slice image data from the volume data,
- acquire a plurality of pieces of first processed image data respectively corresponding to the plurality pieces of the slice image data by respectively subjecting the acquired plurality of pieces of the slice image data to differential processing as first processing,
- acquire a plurality of pieces of second processed image data by subjecting the acquired plurality of pieces of the first processed image data to second processing including addition processing, detect an edge of the subject based on the acquired plurality of pieces of the second processed image data, and
- acquire edge image data including the detected edge of the subject.
