A DEVICE AND METHOD FOR LASER PHOTOTHERMOTHERAPY

摘要

Photothermotherapy is effected by pulsed ultraviolet, visible or infrared laser radiation passing through a system (3) that assures the necessary laser pulse fluence to a biotissue treatment region. While the pulsed local heating of microregions in the tissue reaches therapeutic levels a unit (4) measuring the local heating by a single pulse and the average heating by a train of pulses controls, by way of feedback, a control unit (2) which determines the pulse energy and repetition period and the total exposure dose to provide a required therapeutic effect without risk of thermal damage to the exposed tissue region.
