Abstract :
A method of dose field control in patient´s body during radiation treatment is proposed. It is based on detection of thermoacoustic pulse to be generated by pulsed radiation beam in vivo and on reconstruction of dose field characteristics by stress amplitude. A possible scheme of realization of the proposed method is considered. Typical variants of dose fields and corresponding solutions of radiation thermoacoustic equation are discussed. The values of stress pulses and accuracy of dose field location are estimated for electron, X-ray and proton beams.
