Development of a database and analytical environment for precision quality management in high-precision radiotherapy. [PDF]

J Appl Clin Med Phys
Abstract Background High‐precision radiotherapy, especially intensity‐modulated radiotherapy (IMRT), requires stringent quality assurance (QA) owing to its complexity. Moreover, patient‐specific QA (PSQA) is essential to ensure accurate dose delivery. Purpose This study aimed to develop a centralized PSQA database and analytical environment to improve ...

Feasibility of treatment planning with HyperArc stereotactic radiosurgery methods for ocular tumors. [PDF]

J Appl Clin Med Phys
Abstract Purpose/objectives Currently, ocular disease is primarily managed with COMS plaque brachytherapy. Various stereotactic radiosurgery (SRS) platforms have also been employed, yet widespread access remains a challenge. Herein, we demonstrate the feasibility of using the HyperArc SRS system to provide an additional platform for the treatment of ...

Dosimetric characterization of a liquid-filled ion chamber array post upgrade and evaluation of improvements for stereotactic plan verification. [PDF]

J Appl Clin Med Phys
Abstract Background Stereotactic ablative radiotherapy (SABR) is a technique developed for delivery of high doses of radiation to target volumes. Standard delivery methods for SABR include dynamic conformal arc therapy (DCAT) and volumetric modulated arc therapy (VMAT) as they allow for meaningful gains in delivery speed and in some instances sparing ...
