MEDICAL DEVICE INCLUDING SCANNED BEAM UNIT WITH OPERATIONAL CONTROL FEATURES

摘要

A method of controlling a medical device is provided. The method includes generating a beam of radiation using a radiation source assembly. The beam of radiation is directed toward a distal end of the medical device using an optical fiber. The beam of radiation is directed onto an area of interest by scanning the reflector in a scanning pattern, the reflector receiving the beam of radiation from the optical fiber. Radiation is collected from the area of interest using a collector to generate a signal for use in producing a viewable image. A loss of scan condition of the reflector is detected automatically by a control system.
