CONTACT RADIATION THERAPY (BRACHYTHERAPY): CLINICAL CONCEPT OF DIRECT DOSIMETRY [IN VIVO] AND QUALITY ASSURANCE OF RADIATION THERAPY

Abstract

Contact radiation therapy (brachytherapy): the clinical concept of direct dosimetry [in vivo] and quality assurance of radiation therapy the issues of organizing the brachytherapy process with the possibility of confirming the calculated doses obtained on planning systems by direct dosimetry with scintillation small-size dosimeters with the technology of their placement, fixation and visualization are Considered. The coincidence of the calculation data with the measurement results helps to improve quality assurance, especially when using the fractionation mode of a single focal dose of more than 5-6 Gr.
