A Novel Phantom Model For Mouse Tumor Dose Assessment Under MV Beams
By: Michael Gossman, MS, DABR, RSO, et al
Abstract -- In order to determine a mouse's dose accurately and prior to engaging in live mouse radiobiological research, a tissue-equivalent tumor-bearing phantom mouse was constructed and bored to accommodate detectors. Comparisons were made among four different types of radiation detectors, each inserted into the mouse phantom for radiation measurement under a 6 MV linear accelerator beam.

As promulgated by the Nuclear Regulatory Commission, packaging regulations for radioactive material are confusing (e.g., “activity” vs “contained” activity vs “total” activity). As a consequence, medical physicists are forced to secondguess the intent of the regulations.

Vascular access ports are used widely in the administering of drugs for radiation oncology patients. Their dosimetric effect on radiation therapy delivery in photon beams has not been rigorously established. In this work, the effects on external beam fields when any of a variety of vascular access ports were included in the path of a high energy beam are studied. This study specifically identifies sidescatter and backscatter consequences as well as attenuation effects.
