Commissioning An Anthropomorphic Spine and Lung Phantom For Remote Dose Verification of Institutions Participating In Rtog 0631
The RPC developed a new phantom to ensure comparable and consistent radiation administration in spinal radiosurgery clinical trials. This study assessed the phantom’s dosimetric and anatomic utility. The ‘spine phantom’ is a water filled thorax with anatomy encountered in spinal radiosurgery: …

Mindful self-hypnosis combined with resistance training for reducing perceived stress in female college students.
… groups: MSH combined with RT (MSHRT), RT only (RTOG), or waitlist list control (WLCG). Participants in both MSHRT and RTOG performed three forty-minute RT sessions each week while those in MSHRT also received 5 minutes of MSH before and after RT sessions. Results indicated significant and large …

The Development and Implementation of An Anthropomorphic Head Phantom For The Assessment of Proton Therapy Treatment Procedures
<p>Proton therapy has become an increasingly more common method of radiation therapy, with the dose sparing to distal tissue making it an appealing option, particularly for treatment of brain tumors. This study sought to develop a head phantom for the Radiological Physics Center (RPC), the first to …
