A new technique for dynamic irradiation of deep–seated targets of complex shape has been developed at the Medical–Technical Complex of the Joint Institute of Nuclear Research (Dubna). The technique is implemented using a variable–thickness automated range shifter and a multileaf collimator. The devices were constructed taking cognizance of the characteristics of the existing system for forming radiotherapy proton beams. Preliminary results of dosimetry measurements demonstrated better irradiation field conformity compared to the standard technique of 3D passive conformal proton radiotherapy.
