At the AAPM Spring Clinical Meeting, Thayer School of Engineering PhD Student Muhammad (Ramish) Ashraf took the third place prize in the Young Investigator’s Symposium.
Ramish’s talk was titled “Remote, Real-Time and High-Resolution Optical Imaging of Small Beamlets in Radiotherapy” and it evaluated the use of Radioluminescence as a Quality Assurance (QA) tool for small beamlets in radiotherapy. Optical Imaging can be used to image a variety of dynamic Volumetric Modulated Arc Therapy (VMAT) and Stereotactic RadioSurgery (SRS) plans. The technique is sensitive to MLC and Gantry Angle errors. High spatial resolution renders the technique a viable solution for small field dosimetry.
