In vivo dosimetry during pelvic treatment
Radiotherapy and Oncology, 1992High precision in vivo entrance and exit dose measurements have been performed with p-type diodes on patients during 8 MV X-ray irradiation of the pelvis, to investigate the accuracy of dose calculations in this region. Based on phantom measurements the accuracy of the p-type diode measuring system itself, i.e.

In vivo dosimetry is an essential tool in quality-assurance programs. It is important to check the dose delivered to patients undergoing radiation treatment to avoid over or underdosing in areas in which assurance of planning accuracy may be needed. Radiochromic films are uniquely able to measure not only point doses but also two-dimensional maps of ...

Radiotherapy and Oncology, 1993
In recent years, numerous publications have shown the feasibility and usefulness of in vivo dosimetry as an essential tool of quality assurance programs in radiotherapy [ 1,3,6,11]. In the context of this meeting on high dose/high precision radiotherapy, the presentations and discussions on in vivo dosimetry centred on its value for investigating the ...

Physics in Medicine and Biology, 1997
This paper starts with definitions of radiance, fluence (rate) and other quantities that are important with regard to in vivo light dosimetry. The light distribution in mammalian tissues can be estimated from model calculations using measured optical properties or from direct measurements of fluence rate using a suitable detector.
