,Positron Emission Tomography — Basic Principles, Corrections and Camera Design,Fig. 1). A number of positron cameras with widely varying design parameters have been developed for this purpose. Some are designed to study activity distribution in different parts of the body. Others are dedicated to the brain. The data obtained are used to reconstruct images describing the distri

NMR Imaging: Principles, Algorithms and Systems,search and development centers all over the world (1–6). It is also becoming apparent, now, that the recently obtained image quality appears to be close to X-ray CT images in resolution and superior in many other aspects, such as contrast sensitivity.

Matched Filtering for Digital Subtraction Angiography, application of these subtraction methods has been in conjunction with intravenous angiography; although, intra-arterial studies also benefit from such processig (10). All these methods may be lumped together under the heading “digital subtraction angiography”.
