DEVICE FOR INTRAOPERATIVE RADIOTHERAPY FOR TREATMENT OF CANCER PATIENTS

摘要

IORT device (10) for radiation therapy of cancer patients, containing a source of particles; an accelerating device (11) that directs a beam (12) of particles to a target (14) through an applicator (15); a scattering filter (16) that allows the distance between the particle source and the target (14) to be maintained in a range compatible with the use of IORT devices (10) in standard operating rooms; and an optical system for collimating the particle beam (12), which is located between the scattering filter (16) and the applicator (15); the optical collimating system of the particle beam contains a primary screen (17) configured to screen the radiation generated by the scattering filter (16); a secondary shield (18) configured to screen photons generated on the primary shield (17); and a collimator (19) that accommodates the control chambers (20).
