Quality assurance devices for dynamic conformal radiotherapy [PDF]

open access: yesJournal of Applied Clinical Medical Physics, 2004
Two quality control devices, a light‐field device and a radiation‐field device, have been specially designed to assist the clinical implementation of conformal dynamic arc treatment (CDAT) and intensity‐modulated radiation therapy (IMRT). With these devices, the light field as well as the radiation field projected from the individual beams at any ...

A brief review of low-dose rate (LDR) and high-dose rate (HDR) brachytherapy boost for high-risk prostate [PDF]

open access: yes, 2019
For patients with unfavorable or high-risk prostate cancer, dose escalated radiation therapy leads to improved progression free survival but attempts to deliver increased dose by external beam radiation therapy (EBRT) alone can be limited by late ...

A high-precision system for conformal intracranial radiotherapy

open access: yesInternational Journal of Radiation Oncology*Biology*Physics, 2000
Currently, optimally precise delivery of intracranial radiotherapy is possible with stereotactic radiosurgery and fractionated stereotactic radiotherapy. We report on an optimally precise optically guided system for three-dimensional (3D) conformal radiotherapy using multiple noncoplanar fixed fields.The optically guided system detects infrared light ...
