A method and system are disclosed for radiosurgical treatment of moving tissues of the heart, including acquiring at least one volume of the tissue and acquiring at least one ultrasound data set, image or volume of the tissue using an ultrasound transducer disposed at a position. A similarity measure is computed between the ultrasound image or volume and the acquired volume or a simulated ultrasound data set, image or volume. A robot is configured in response to the similarity measure and the position of the transducer, and a radiation beam is fired from the configured robot.

Apparatus and method for real-time tracking of tissue structures

A method for measuring skin thickness. The method includes at a first 3D point on an outer surface of a patient, exposing the first point to near infrared (NIR) energy from an NIR source. The method includes measuring reflected energy emanating near the first 3D point, or beam incident point. The method includes determining a pattern of the reflected energy based on a distance from a center of the reflected energy, wherein the center is approximated by the first 3D point. The method includes determining a skin thickness measurement based on the pattern.
