Comparative Retrospective Study Of Proton Arc Planning With Elsa Algorithm And Impt With Monte Carlo Algorithm With Raystation Treatment Planning System, Matthew L. Carpenter Ms, Msha, Bsrt(R)(T)

Culminating Experience Projects

Proton arc therapy (PAT) will become widely available soon. It is crucial to determine if this technique and the associated calculation algorithms provided by treatment planning system vendors compete favorably with established proton therapy techniques like intensity modulated proton therapy (IMPT) and the Monte Carlo dose calculation algorithm used to compute IMPT doses in today’s clinic. RaySearch Laboratories have produced a modified Monte Carlo algorithm called ELSA.

ELSA stands for early layer spot assignment and is RaySearch Laboratories proposed solution to reduce optimization time during treatment planning for PAT. This research study will look at proton plan robustness to determine …

Particle Arc Single-Isocenter Stereotactic Radiosurgery Of Multiple Brain Metastases, L Volz, S Mein, T Tessonnier, Peilin Liu, A Mairani, M Durante, Xuanfeng Ding, C Graeff, T Li

Conference Presentation Abstracts

Purpose: To develop spot-scanning proton (SPArc) and heavy ion (SHArc) arc therapy for single-isocenter stereotatic radiosurgery (SISRS) of multiple brain metastases (MBMs). First results achieved with dedicated planning infrastructure are compared to state-of-the -art volumetric modulated photon arc therapy (HA-VMAT). Methods: A multi-institutional collaboration was established to develop bespoke SPArc and SHArc SISRS infrastructure with available research and commercial treatment planning systems. Devised planning and delivery methods considered dedicated energy, spot, and multi-arc selection strategies. SPArc and SHArc (carbon and helium ions) plans were generated for MBM patients exhibiting 3-12 intracranial lesions with GTV volumes between 0.03ccm and 19.8ccm, at …

The Development And Implementation Of An Anthropomorphic Head Phantom For The Assessment Of Proton Therapy Treatment Procedures, Paige A. Summers

Dissertations & Theses (Open Access)

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 be used for credentialing of institutions wishing to participate in clinical trials involving brain tumor treatment of proton therapy. It was hypothesized that a head phantom could be created for the evaluation of proton therapy treatment procedures (treatment simulation, planning, and delivery) to assure agreement between the measured dose and calculated dose within …
