A publication by Irwin Tendler, a PhD student at the Thayer School, in the Red Journal of the American Society for Radiation Oncology (ASTRO) has garnered much attention lately through tweets and other online buzz.
The paper, entitled “Experimentally Observed Cherenkov Light Generation in the Eye During Radiation Therapy,” reports that Dartmouth researchers have produced evidence of the flashes of light that patients report seeing during radiation treatment, even when their eyes are closed. It helps explain the phenomenon and will benefit future research efforts.
Here are some of the recent reports about this exciting development:
Congratulations to Thayer PhD student Daniel Alexander, whose scientific abstract was awarded one of the “Top 3” prizes by the Physics Section of The Radiosurgery Society.
Dan will present his paper, “Cherenkov Imaging for Adaptive Replanning Guidance in Head and Neck Radiotherapy,” at the group’s 2020 Annual Scientific Meeting in April, which is focused on the use of precision therapies to improve patient care.
Ethan LaRochelle recently attended the World Molecular Imaging Congress (WMIC) in Montreal. His abstract titled “Real-time non-contact in vivo pO2 imaging during radiotherapy of unanesthetized mice,” was selected as one of the best abstracts at the conference. Ethan presented this work during the Highlights in Instrumentation & Methodology session. Thayer faculty Kimberley Samkoe PhD and Jonathan Elliot PhD, and Optics in Medicine collaborator Dr. Eric Henderson, also attended and presented research at the conference.

At this year’s SPIE International Graduate Summer School for Biophotonics, Thayer PhD student Samuel Streeter won the Best Poster Presentation award. His work was titled “High Spatial Frequency Structured Light Imaging Texture Analysis for Rapid and Wide Field-of-View Surface Tissue Characterization.” Congratulations Sam!
This was the 9th International Graduate summer school and was focused on the study of optical methods and instruments that use light to measure interactions with tissue for diagnosis and treatment monitoring. The program is taught by internationally renowned experts in biophotonics, this year including Thayer Professor Brian Pogue.
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.
