COMS Eye Plaque Builds Using 3D Printed Template Stamps and Duralay

Authors: Vishruta A. Dumane, Andrew Lukban, Charlotte Elizabeth Read, Mario Serrano-Sosa, Ren-Dih Sheu, Nadia M. Vassell

Affiliation: Icahn School of Medicine at Mount Sinai, Mount Sinai Beth Israel

Abstract Preview: Purpose:
Defined seed positions are used when following the COMS formalism for eye plaques. Au inserts are typically used as templates for placement of radioactive seeds and then covered in Duralay...

Comparison of Biological Effectiveness of COMS Eye Plaques with I-125 and Pd-103 Sources Using Equivalent Uniform RBE-Weighted Dose

Authors: Jonathan J. Chen, Alexei V. Chvetsov, Yulun He, Ramesh Rengan, Andrew Stacey, Kent Wallner

Affiliation: University of Washington and Fred Hutchinson Cancer Center, University of Washington

Abstract Preview: Purpose: To show that the RBE of low-energy photon sources used in COMS (Collaborative Ocular Melanoma Study) eye plaques compensates for protracted irradiation and attenuation of low-energy photons i...

Development and Clinical Validation of Hyperarc Stereotactic Radiosurgery Method for Intraocular Tumors

Authors: Chase Cochran, Damodar Pokhrel, William St Clair

Affiliation: University of Kentucky, Department of Radiation Medicine, University of Kentucky, Radiation Medicine

Abstract Preview: Purpose: Currently, intraocular disease is primarily treated via COMS-plaques brachytherapy. Various stereotactic approaches via photons/proton beam have also been implemented (CyberKnife/GammaKnife/p...

Interplay of Relative Biological Effectiveness and Dose Rate in Eye Plaque Brachytherapy with Low Energy Photons

Authors: Alexei V. Chvetsov, Sunan Cui, Sunyoung Jang, Robert D. Stewart

Affiliation: University of Washington and Fred Hutchinson Cancer Center, Penn State College of Medicine, University of Washington

Abstract Preview: Purpose: To evaluate spatial variation of relative biological effectiveness (RBE) in COMS (Collaborative Ocular Melanoma Study) eye plaques with low energy 125I and 103Pd photon sources as a function ...

Leveraging Hybrid Quantum Solvers for Eye Plaque Brachytherapy Treatment Planning Optimization

Authors: Xianjin Dai, PhD, Wu Liu, Eric Nguyen, Lei Xing, Lewei Zhao

Affiliation: Department of Radiation Oncology, University of California, Los Angeles, Department of Radiation Oncology, Stanford University

Abstract Preview: Purpose: Recent developments in hybrid quantum solvers, which combine quantum and classical processing, enable greater flexibility to tackle problems outside the limited scope of pure quantum computin...

Reducing Radiation Exposure in Building COMS Eye Plaque with a Dental Resin Carrier Template

Authors: Andrew Lukban, Kiran Pant, Charlotte Elizabeth Read, Ren-Dih Sheu

Affiliation: Icahn School of Medicine at Mount Sinai, Mount Sinai Health System, Icahn School of Medicine at Mount Sinai, Department of Radiation Oncology

Abstract Preview: Purpose: Ophthalmic brachytherapy relies on Collaborative Ocular Melanoma Study (COMS) protocol and its updated reports. Their reports provide standardized methods for eye plaque brachytherapy, descri...

Affiliation: Icahn School of Medicine at Mount Sinai, Mount Sinai Beth Israel, Icahn School of Medicine at Mount Sinai, Department of Radiation Oncology

Abstract Preview: Purpose: This work introduces a refined in-house modified COMS eye plaque management system to streamline processes, reduce redundancies, and enhance usability.
Methods: A web-based application wit...

Use of Gold Nanoparticles As Shielding during Eye Plaque Brachytherapy

Authors: Clara Ferreira, Tomas Agustin Montenegro, Courtney C. Oare

Affiliation: University of Minnesota

Abstract Preview: Purpose: This work provides a simulated proof of concept for the use of intravitreal gold nanoparticle (AuNP) during eye plaque brachytherapy as a radiation shield to critical structures in the eye us...
