First Claim
Patent Images
1. A system for monitoring laser therapy of a target tissue, the system comprising:
- a therapeutic control unit having a first light source configured to deliver light to the target tissue for therapy;
an ultrasonic transducer for receiving photoacoustic signals generated due to optical absorption of light energy by the target tissue; and
a monitoring control unit in communication with the ultrasonic transducer for reconstructing photoacoustic tomographic images from the received photoacoustic signals to provide an optical energy deposition map of the target tissue.
