Miniature semiconductor detectors for in vivo dosimetry

Radiation Protection Dosimetry, 2006
Silicon mini-semiconductor detectors are found in wide applications for in vivo personal dosimetry and dosimetry and microdosimetry of different radiation oncology modalities. These applications are based on integral and spectroscopy modes of metal oxide semiconductor field effect transistor and silicon p-n junction detectors.

Generalized EPID calibration for in vivo transit dosimetry

Physica Medica, 2011
Many researchers are studying new in vivo dosimetry methods based on the use of Elelctronic portal imaging devices (EPIDs) that are simple and efficient in their daily use. However the need of time consuming implementation measurements with solid water phantoms for the in vivo dosimetry implementation can discourage someone in their use.

EPID in vivo Dosimetry

2018
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.

In vivo dosimetry during pelvic treatment

Radiotherapy and Oncology, 1992
High 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.

Midline Dose Algorithm for in Vivo Dosimetry

Medical Dosimetry, 1994
The 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 ...

Catching errors with in vivo EPID dosimetry

Medical Physics, 2010
The potential for detrimental incidents and the ever increasing complexity of patient treatments emphasize the need for accurate dosimetric verification in radiotherapy. For this reason, all curative treatments are verified, either pretreatment or in vivo, by electronic portal imaging device (EPID) dosimetry in the Radiation Oncology Department of the ...

In Vivo Dosimetry for BNCT

2000
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.

Implementation of in vivo dosimetry with epigray

Physica Medica, 2013
Background 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.

Real-Time In Vivo Dosimetry

2017
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 ...

Skin in vivo Dosimetry in Radiotherapy

2018
Introduction: 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.
