Abstract:
A system for delivering an energy beam transmitted through a non-uniform tissue medium in a body, comprising:a transmitter comprising a plurality of transmitting elements configured to deliver respective energy waves from outside the body through the non-uniform tissue medium to a target tissue area in the body, the energy waves collectively comprising the energy beam; a detector having a known position relative to the transmitting elements, the detector configured to receive a signal representing the intensity of reflected portions of the beam along a line-of-sight axis within the body; and a controller coupled to the transmitter and detector, the controller configured to calculate the location and intensity of the reflected beam portions along the axis based on the timing of the received signal, the controller further configured to adjust transmission parameters of one or more of the transmitting elements based on the location, intensity, or both, of the reflected beam portions.
