ABSTRACT:
The invention provides an NMR machine capable of a volume scan. Initial data is provided for a plurality of planes in the body, instead of a plurality of lines as previously, and this is repeated at different positions rotated about an axis parallel to the plane. Convolution processing thus yields data for a matrix of lines parallel to that axis. Further rotation about the z-axis and repetition of the previous analysis at each stage yields data for such matrices of lines at different angles to the z-axis and further convolution processing provides data for a three-dimensional matrix of elements in the body. The last mentioned processing may be done in individual ones of parallel planes.
