A comparison of protocols for external beam radiotherapy beam calibrations
Applied Radiation and Isotopes, 2012A number of codes of practice (CoP) for electron and photon radiotherapy beam dosimetry are currently in use. Comparison is made of the more widely used of these, specifically those of the International Atomic Energy Agency (IAEA TRS-398), the American Association of Physicists in Medicine (AAPM TG-51) and the Institute of Physics and Engineering in ...

While surgery, radioiodine therapy (RIT) and TSH suppression therapy are generally accepted mainstays of therapy for differentiated thyroid carcinoma (DTC) [52, 67, 76], the role of external beam radiotherapy (RTx) remains controversial. Unequivocal indications for RTx of thyroid neoplasms are undifferentiated/ anaplastic thyroid carcinoma, thyroid ...

Radiotherapy: external beam radiotherapy
2015Design principles for radiotherapy facilities using X-ray, γ-ray, and electron beams are described, especially the requirements for primary and secondary shielding and maze and door entrances. These features are illustrated with reference to the shielded rooms (bunkers) required for linear accelerators, and example calculations are included for ...

Dose calculations for external photon beams in radiotherapy
Physics in Medicine and Biology, 1999Dose calculation methods for photon beams are reviewed in the context of radiation therapy treatment planning. Following introductory summaries on photon beam characteristics and clinical requirements on dose calculations, calculation methods are described in order of increasing explicitness of particle transport.

Teletherapy, sometimes called external beam radiotherapy, is the treatment of cancer using apparatus such as a deep therapy X-ray machine, linear accelerator or cobalt-60 machine. Because of the lack of penetration of the X-ray beams from the early therapy apparatus, the initial years of X-ray therapy although recording successes with superficial ...

Contemporary External Beam Radiotherapy
2012External beam radiation therapy (EBRT) has a longstanding history in the treatment of prostate cancer, however the technique of therapy has evolved dramatically. The development of technology for localization of the target volume and shaping of the high-dose regions of the radiation beam have increased disease control and reduced toxicity.

Relocatable frame for stereotactic external beam radiotherapy
International Journal of Radiation Oncology*Biology*Physics, 1991A non-invasive head fixation system is described which is accurately relocatable and enables the transfer of stereotactic positions between a variety of radiodiagnostic images and therapeutic procedures. The system can be simply and repeatedly applied for planning stereotactic radiation therapy from one or more diagnostic images and for repeated ...

3D Simulation of external beam radiotherapy
2004Radiation therapy treatment is a very demanding cancer treatment process. The aim of the treatment is to cure or to limit the disease using high-energy radiation dose, having as minimum as possible damage on healthy tissues. In order to have the wanted results, the process is composed from several steps that are highly depended to each other. One could

Improved external beam radiotherapy for the treatment of retinoblastoma
The British Journal of Radiology, 1987An applicator attached to a 6 MV linear accelerator has been adapted to produce a well defined beam for the treatment of retinoblastoma. By using a contact lens as the reference point on the patient's cornea, the beam edge is aligned to just behind the posterior margin of the crystalline lens, thus sparing the anterior chamber and lens from the ...

External Beam Radiotherapy for Differentiated Thyroid Cancer
Clinical Oncology, 2010The management of differentiated thyroid cancer involves a combination of surgery, thyroid stimulating hormone suppression and radioactive iodine for most patients. In a small subset of patients, external beam radiotherapy is also used. However, its role remains controversial and there are no randomised controlled trials to guide practice.
