In vivo dosimetry in brachytherapy [PDF]

Medical Physics, 2013
In vivo dosimetry (IVD) has been used in brachytherapy (BT) for decades with a number of different detectors and measurement technologies. However, IVD in BT has been subject to certain difficulties and complexities, in particular due to challenges of the high‐gradient BT dose distribution and the large range of dose and dose rate.

Breast in vivo dosimetry by EPID [PDF]

Journal of Applied Clinical Medical Physics, 2010
An electronic portal imaging device (EPID) is an effective detector for in vivo transit dosimetry. In fact, it supplies two‐dimensional information, does not require special efforts to be used during patient treatment, and can supply data in real time.

In vivo EPR for dosimetry [PDF]

Radiation Measurements, 2007
As a result of terrorism, accident, or war, populations potentially can be exposed to doses of ionizing radiation that could cause direct clinical effects within days or weeks. There is a critical need to determine the magnitude of the exposure to individuals so that those with significant risk have appropriate procedures initiated immediately, while ...
