In vivo dosimetry has a well established role in the quality assurance of 2D radiotherapy and 3D conformal radiotherapy. The role of in vivo dosimetry for IMRT is not as well established. IMRT introduces a range of technical issues that complicate in vivo dosimetry.

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.

Radiology, 1970
Abstract The authors describe the design and development of systems for direct in vivo measurement of dose within the living subject. They have used the method since 1957 for therapy, diagnosis, nuclear medicine, and radio-biology. The systems include home-grown and commercial luminescent solid state dosimeters of various types and geometries, read-out

Clinical in vivo dosimetry using optical fibers
Radiation Oncology Investigations, 1998Discoloring of glass due to ionizing radiation depends on the absorbed dose. The radiation-induced light attenuation in optical fibers may be used as a measure of the dose. In high-energy photon beams (6 MV X rays), a lead-doped silica fiber can be calibrated.

Miniature semiconductor detectors for in vivo dosimetry
Radiation Protection Dosimetry, 2006Silicon 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.

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 ...

Evaluation of Ge-doped silica fibre TLDs for in vivo dosimetry during intraoperative radiotherapy
Physics in Medicine and Biology, 2019Ge-doped silica fibre (GDSF) thermoluminescence dosimeters (TLD) are non-hygroscopic spatially high-resolution radiation sensors with demonstrated potential for radiotherapy dosimetry applications. The INTRABEAM® system with spherical applicators, one of

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 ...
