Concurrent display and adjustment of 3D projection, coronal slice, sagittal slice, and transverse slice images

摘要: A CT scanner (A) non-invasively examines a volumetric region of subject and generates image data indicative thereof. An object memory (B) stores the values corresponding to each voxel volume region. affine transform algorithm (60) operates on visible faces (24, 26, 28) translate from space projections onto viewing plane in space. operator control console (E) includes controls for selecting an angular orientation projection relative plane, i.e. video display (20). cursor positioning trackball (90) inputs i- j-coordinate locations which are converted (92) into crosshair (30) (22). depth dimension k between direction perpendicular is determined (74). The (i,j,k) location operated upon by reverse selected identify (x,y,z) coordinate translated (100, 102,104) addresses transverse, coronal, sagittal planes (10, 12, 14) through
