ABSTRACT:
A multi-dimensional data set acquired by non-intrusive means with the use of a surface coil of internal structures of internal structures of a subject. The data set is adjusted for the differential sensitivity of the surface coil with respect to distance from the coil and angle in relation to the coil. The adjusted data set then is searched for abrupt changes in value in the data set indicating surfaces. The surfaces then may be manipulated, shaded, color coded and displayed. This is particularly useful in when employed on a data set which images blood for providing surface images of coronary arteries of the subject for non-invasive detection of occlusion and stenosis.
