Thermal treatment system for moving target region of biological tissue uses control unit to locate treatment point in target region from estimated position and time delay

摘要

A thermal treatment system, designed for non-invasive hyperthermic treatment of a moving target region of biological tissue, using a computer (6) to estimate the location of the target region from a measurement signal, comprises a control unit (7) to locate a point (P) for treatment in the target region as a function of the estimated position and a delay in location between the measurement signal and point location, where the system can also include a means of modelling the movement of the target region from a succession of measuring signals and its anticipated spatial position.
