ABSTRACT:
A magnetic resonance angiogram is produced by projecting a 3D array of motion sensitized NMR data. A mask which locates the vessels in the 3D array is produced by thresholding the NMR data, and this mask is combined with the 3D NMR data set to exclude signals produced by surrounding stationary tissues. An integration projection technique is used to produce the angiogram from the masked data set.
