ABSTRACT:
A tomography machine with gamma ray detection has a collimator, the arrangements of holes of which are focused on a geometric slice of a patient's body, the slice having a thickness determined a priori, for the examination of the slice. Reconstructed tomographic images of this body are obtained swiftly and efficiently. By shifting the tomography machine longitudinally, images of adjacent slices are obtained. This technique makes it possible to work with greater speed than by acquiring comprehensive 2D image projections of the entire body to be studied.
