Design and Validation of a Prototype Collimation System with Reduced Applicator Weights for Elekta Electron Therapy Beams
… was to design an electron collimation system for Elekta Infinity accelerators with significantly reduced applicator weights, while maintaining acceptable in-field beam flatness and out-of-field leakage dose. The design was restricted to 6-20 MeV beams for 6x6 to 25x25 cm2 applicators at 100 cm SSD …

Volumetric Modulated Arc Therapy Evaluation With The Radiological Physics Center Head and Neck Phantom
… of this project was to compare two VMAT systems, Elekta VMAT and Varian RapidArc, to the current standard of care, IMRT, in terms of both treatment plan quality and dosimetric delivery accuracy using the Radiological Physics Center (RPC) head and neck (H&N) phantom. Clinically relevant treatment …

Development of A New Independent Monte Carlo Dose Calculation Quality Assurance Audit to ol For Clinical Trials
… source models representing the output of Elekta 6MV and 10MV and Varian TrueBeam Flattening Filter Free (FFF) 6MV and FFF 10MV therapeutic x-ray beams were developed. The Monte Carlo technique, using the Dose Planning Method (DPM) algorithm, was used in radiation dose calculations. During …

Detectors in Medical Physics Measuring Dose by Detectors
… at dmax for two energies 6 MV and 10 MV on the Elekta machine. This was done by using only two points and comparing the results with percentage depth dose (PDD) for the depth dose curve for both energies. In addition the doses were obtained by using three method of detectors suck as the ion …

A phantom based evaluation on the effects of patient breathing motion on Stereotactic Body Radiotherapy treatment volumes
… data. Two treatment planning systems (Monaco, (Elekta) and Eclipse (Varian)) were used to determine the dosimetric characteristics of the materials. This was compared to actual dose as delivered by a linear accelerator (Elekta Synergy). Results: Paths were calculated from the breathing cycles …

End-to-end testing of the Leksell Gamma Knife Icon system
… However, the newest gamma knife model from Elekta, the Icon, introduced a frameless treatment option that utilizes an on-board cone-beam computed tomography (CBCT) imager for patient positioning and a motion tracking system to monitor patient movement during treatment. When using this …
