Radar pulses reflected from the patient are picked up by the antenna and conducted to a receiver. Predetermined radar pulses are selected from among the received pulses by a timer/gate circuit connected to the receiver. The selected radar pulses correspond to a predetermined area of interest within the patient. A representation of the predetermined area within the patient may be displayed with known display apparatus. The antenna may also be moved relative to the patient, in order to produce three-dimensional information. Synchronizing the transmitter, the time/gate device, and the movement of the antenna may be effected with a synch processor, and a matrix filter may be used to focus the emitted radar pulses and to reduce noise in the return radar pulses.Other References
