Characteristics ofin vivoradiotherapy dosimetry
The British Journal of Radiology, 2009The recent discussion and debate about the use of in vivo dosimetry as a routine component of the radiotherapy treatment process has not included the limitations introduced by the physical characteristics of the detectors. Although a robust calibration procedure will ensure acceptable uncertainties in the measurements of tumour dose, further work is ...

Introduction: The most modern radiotherapy devices are equipped with an Electronic Portal Imaging Device (EPID) system which is located on opposite side of the machine’s head. EPID system is often used to setting up the position verification during or between radiotherapy sessions.

A practical approach to diode based in vivo dosimetry for intensity modulated radiotherapy [PDF]
Radiotherapy and Oncology, 2011 A method for in vivo entrance dosimetry, using point detectors, in intensity modulated radiotherapy has been clinically evaluated. Diode dosimetry was performed for treatments of the head and neck and prostate regions. The results were good; 92.2% of the

Midline Dose Algorithm for in Vivo Dosimetry
Medical Dosimetry, 1994The high level of accuracy required in radiotherapy treatment dosimetry makes necessary good treatment quality control. The common way is the use of in vivo dosimetry equipment that allows the direct measurement of dose delivered to the patient. Control of homogeneity and constancy of the incident beam on the patient can be achieved directly by means ...

Implementation of in vivo dosimetry with epigray
Physica Medica, 2013Background EPIGRAY allows in vivo dosimetry with portal imaging. The Medical Physics Unit of CORT37 wishes to implement this technique. Objectives The objective is to test the validity of Results given by EPIGRAY and to determine the limitations of computation and the ability to detect errors.

A phase I BNCT trial in glioblastoma started at the Finnish BNCT facility in May 1999. The aim of the present work was to verify the doses calculated in treatment planning and estimate the whole body dose on the basis of neutron fluence and gamma dose measurements in vivo and in a whole body phantom.

Skin in vivo Dosimetry in Radiotherapy
2018Introduction: Due to the prevalence of skin problems in patients after radiotherapy, skin dose measuring is importance. Content: Skin in vivo dosimetry means measuring the patient's (or phantom) skin dose during radiotherapy. According to the ICRP 59, the dose at the depth of 0.07 mm is known as a skin dose.

The pursuit of in vivo dosimetry (IVD) in brachytherapy has been the subject of investigation by prominent research groups around world. The characteristic features of high-dose rate (HDR) brachytherapy treatments are in many cases also the drivers of the need for a solution: HDRs, few fractions, highly conformal dose distributions, with steep dose ...
