3D Printing Assisted Collimator Design for Fan Beam-Based X-Ray Fluorescence Tomographic Imaging

Authors: Brett Bocian, Nesrin Dogan, John C. Ford, Alan Pollack, Ryder Marshall Schmidt, Junwei Shi, Jorge D Vega

Affiliation: University of Miami, University of Miami Sylvester Comprehensive Cancer Center

Abstract Preview: Purpose: X-ray fluorescence computed tomography (XFCT) is an emerging molecular imaging modality gaining attention in cancer theranostics with high-Z metal nanoparticles (MNPs). While XFCT has been de...

Assessment of the Radiological Features of 3D-Printed Polylactic Acid Composites for Creating Personalized Dosimetric Phantoms

Authors: Ashish Binjola, Raj Kishore Bisht, Natanasabapathi Gopishankar, Pratik Kumar, Daya Nand Kishore Sharma, Sukhvir Kishore Singh, Subramani Vellaiyan

Affiliation: Medical Physics Unit, All India Institute of Medical Sciences, All India Institute of Medical Sciences, Department of Radiological Safety, Institute of Nuclear Medicine and Allied Sciences, Department of Radiation Oncology, All India Institute of Medical Sciences

Abstract Preview: Purpose: Additive manufacturing is increasingly being explored to create dosimetry phantoms. Commercial anthropomorphic phantoms represent an average patient and lack anatomical variations due to obes...

Automated Parametric Custom Collimator Creation for Preclinical Irradiation Studies

Authors: Muhammad Ramish Ashraf, Dixin Chen, Lloyd Emmanuel Kamole Ghomsi, Edward Elliot Graves, Billy W Loo, Stavros Melemenidis, Joseph B. Schulz, Lawrie Skinner

Affiliation: Department of Radiation Oncology, Department of Radiation Oncology, Stanford University School of Medicine

Abstract Preview: Purpose: Precise beam collimation is essential in preclinical radiotherapy studies to ensure accurate dose delivery. Manual design and fabrication of organ-specific collimators usually consist of mult...

Monte Carlo Evaluation of Water-Equivalent Materials for Nanowire-Based Oslds in Flash Radiotherapy

Authors: James Chun Lam Chow, Harry E Ruda

Affiliation: University of Toronto, Princess Margaret Cancer Centre

Abstract Preview: Purpose: FLASH radiotherapy (FLASH-RT) with dose rate greater than 40 Gy/s, has demonstrated potential in reducing normal tissue toxicity while maintaining tumor control. However, accurate and reliabl...
