In vivo dosimetry in pelvic brachytherapy. [PDF]
Br J Radiol, 2022 Brachytherapy is an effective treatment in the curative management of prostate and gynaecological cancers. With advances in technology, brachytherapy has increased in complexity in recent years. Human error, equipment malfunction, patient organ motion and radioactive source displacement can result in substantial deviation of delivered dose from ...

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 ...

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.
