Design, manufacture, and evaluation of an anthropomorphic pelvic phantom purpose-built for radiotherapy dosimetric intercomparison

Abstract

The phantom constructed for the present study incorporates all characteristics necessary for accurate Level III intercomparison studies. Following use in an extensive Level III dosimetric comparison over a large time scale and geographic area, the phantom retained mechanical stability and did not show signs of radiation-induced degradation.

Dosimetric intercomparison for multicenter clinical trials using a patient‐based anatomic pelvic phantom

“…• There were some design and manufacturing anomalies in the phantom that have been described elsewhere. 12 The ability to replace dosimetric materials between irradiations without repositioning the phantom saved considerable time during the measurement process. • The undertaking of this study has allowed estimates to be made of the uncertainties inherent in utilising reported dosimetry as a surrogate for actual patient dosimetry.…”

Radiation dose escalation or longer androgen suppression for locally advanced prostate cancer? Data from the TROG 03.04 RADAR trial

“…Consistency in EBRT dose delivery was assessed via dosimetric audit of centres [3][4][5][6][7] and adherence to trial planning protocol via expert review of each treatment plan [8].…”

Anthropomorphic Phantoms for Radiation Oncology Medical Physics

“…The RPC is not the only QA service to use anthropomorphic body-parts. Harrison et al [21] described the use of a pelvic phantom for an Australian multicenter radiotherapy dosimetry comparison [22]. The Australian pelvic phantom was a solid phantom that had structures representing bone, organ and backfill and it could accommodate the placement of TLD and an ion chamber at various locations.…”
