The task group (TG) for quality assurance of medical accelerators was constituted by the American Association of Physicists in Medicine's Science Council under the direction of the Radiation Therapy Committee and the Quality Assurance and Outcome Improvement Subcommittee. The task group (TG-142) had two main charges. First to update, as needed,(More)
The characteristics of an Elekta Precise treatment machine with a gating interface were investigated. Three detectors were used: a Farmer ionization chamber, a MatriXX ionization chamber array and an in-house, single pulse-measurement ionization chamber (IVC). Measurements were made of dosimetric accuracy, flatness and symmetry characteristics and duty(More)
PURPOSE Knowing the contribution of neutron to collateral effects in treatments is both a complex and a mandatory task. This work aims to present an operative procedure for neutron estimates in any facility using a neutron digital detector. METHODS The authors' previous work established a linear relationship between the total second cancer risk due to(More)

In the 10th year of research Virtual Environments now have come into age. Following the head-mounded technology of the first days, now industrial applications in the VR-Labs of the automotive industry are basically using stereo projection type systems like standard single screens, multiple screens, Responsive Workbenches and also cave-like-projection(More)
