[Return signal processing and problems of laser angioplasty with optical detection of intravascular objects].
The paper deals with the development of devices for visualization on intravascular formations by using multifiber optical catheters, describes a scheme for a pilot testing unit based on periodical pulse-acting Nd:YAG laser that operates at the second harmonics (lambda = 532 nm). Analyzes errors while processing the return signal received by intravascular objects, proposes a statistical model which describes the received signal, which permits the development a of block diagram for an optimized device for initial processing of signals.
