Abstract
A CT system acquires a succession of 2D slice images which are combined to produce a 3D image data set. A projection image is produced from the 3D image data set and serves as an index which enables the operator to select a particular region of interest in the acquired 3D image data set. A specified number and orientation of slice images are then produced through the region of interest.
Claims16
A method for displaying image data acquired with a medical imaging system, the steps comprising:
- a) reconstructing a 3D image data set with the acquired image data;
- b) producing an index image by projecting the 3D image data set;
- c) displaying the index image on a display device;
- d) producing a cursor on the display device which enables manual selection of a region of interest in the 3D image data set;
- e) receiving input data which indicates the number of 2D sectional images to be produced;
- f) receiving input data which indicates the spatial orientation of the 2D sectional images;
- g) producing the 2D sectional images by extracting corresponding image data from the region of interest in the 3D image data set;
- and
- h) displaying the 2D sectional images on a display device.

A CT system which comprises:
- means for acquiring a succession of 2D slice images from a prescribed field of view;
- means for combining the acquired 2D slice images to form a 3D image data set;
- means for producing an index image of the 3D image data set;
