Brachytherapy

UT-HSC Radiation Therapy Course MPHY 6190/8190
Summer Semester 2014

Syllabus, Schedule & Grading Scheme

Brachytherapy is a clinical course designed for MSBS/Ph.D. students in clinical radiation oncology physics track. It is divided into two sections of didactic and laboratory experiments. The aim of the didactic portion of the course is to familiarize students with principles of Brachytherapy, definitions, and methods, various implant techniques and treatment planning dosimetry as per AAPM -TG 43U, as well as hand calculation of dose using actual patient data. In laboratory portion of the course students will gain hands on experience in safe handling of radioactive material in hot lab, radioactive surveys, determination of energy distribution and determination of unknown source strength using HVL concepts, etc.
