Cherenkov Imaging is the method by which the light emitted from a patient’s skin during external beam radiation therapy can be imaged and used to verify dose delivery location. This is accomplished using an intensified CMOS camera time-gated to the linac puls...
Limiting contralateral breast dose (CBD) is an important concern in breast radiotherapy, as prior studies link doses >1Gy to significantly increased secondary cancer risk. Furthermore, complex beam geometry increases low-dose irradiation of healthy tissue whi...
Interstitial brachytherapy enables highly conformal radiotherapy, but accuracy depends on surgical skill, and few in vivo dosimetry systems exist. Effective monitoring requires not just dose but tracking source position, dwell time, and transit times. We deve...
To develop a reliable batch‑calibration method and dose‑reading protocol for in-vivo scintillation imaging dosimetry during radiation therapy.
Cherenkov imaging is a technique used to observe surface dose deposition during radiation therapy. While proportional to dose, the imaged signal cannot derive absolute dose, due to the attenuation and inhomogeneity of human tissue optics. However, controlled,...
Cherenkov imaging provides valuable beam delivery information, but fixed treatment camera positions are subject to gantry occlusions and couch rotation artifacts that inhibit imaging for a significant percentage of clinical cases. To overcome these limitation...
Accurate intraoperative assessment of tissue perfusion is critical for guiding debridement in traumatic and orthopedic injuries. However, existing fluorescence imaging systems are often unsuitable for resource-limited or high-ambient-light environments. This...
