Scintillation Camera Collimators,2–1. There are broadly four types of collimators: parallel hole, converging, diverging, and pinhole. They are described below, with particular attention paid to the principle governing the performance of the parallel hole collimator.

Medical Aspects of Thermography,e latter group includes increased temperature secondary to inflammatory and neoplastic disease, which two causes might possibly be differentiated by circadian rhythm. Research efforts directed toward better discrimination of the thermographic signal, particularly quantitative discrimination, may well prove to be quite rewarding.

General Infrared System Analysis,noise; and the system is virtually ideal. Accordingly, this chapter starts with a derivation of an expression for the signal-to-noise ratio of an ideal infrared imaging system and then considers the efficiency factors of each of the components in turn.

Ultrasonic Imaging: Basic Principles,velength limit of resolution in medical-imaging systems using electromagnetic waves. In radar imaging of aircraft and terrain one attempts to approach the wavelength limit of resolution, so there are many similarities between radar and ultrasonic diagnostic techniques.
