Radiosurgery

The following are descriptions of several radiosurgery research projects that our medical physicists are currently pursuing: Treatment Planning Strategies for Stereotactic Radiosurgery Zac Labby, PhD, FAAPM For intracranial radiosurgery treatments, we seek conformal high-dose radiation dose distributions with exceptionally sharp fall-off of the dose outside the treatment volume. Depending on the exact size, shape and …

Radiation Measurements

The following are descriptions of several radiosurgery research projects that our medical physicists are currently pursuing: Evaluating Low-Dose-Rate Performance of the TrueBeam Radiotherapy System Dustin Jacqmin, PhD During the commissioning of our new TrueBeam linear accelerator, we investigated the dose-rate constancy, MU linearity and profile stability of the TrueBeam radiotherapy delivery system over its full …

MR-guided Radiotherapy

The following are descriptions of several MR-guided radiation therapy research projects that our medical physicists are currently pursuing: MRI-guided Radiation Therapy MRI is an excellent imaging modality for visualization of soft tissues. This is particularly useful for tumors of the abdomen, such as pancreatic cancer shown below.  The left image shows the patient’s anatomy during …

Motion Management

The following are descriptions of several motion management research projects that our medical physicists are currently pursuing: Evaluating the performance of the optical surface imaging systems Dustin Jacqmin, PhD Optical surface imaging systems like AlignRT and the Varian Optical Surface Monitoring System (OSMS) are often used for monitoring patients during frameless stereotactic radiosurgery (SRS). This …

Imaging

The following are descriptions of several imaging research projects that our medical physicists are currently pursuing: Dual Energy Computed Tomography for Bone Delineation Michael Lawless, PhD Using the tools available to us as a part of the Siemens Somatom Definition Edge Dual Energy CT (DECT) scanner, we have the ability to better visualize tissues that …

Clinical Operations

The following are descriptions of several clinical operations research projects that our medical physicists are currently pursuing: Clinical Impact of Treatment Delivery Errors in Radiotherapy The goals of this work are to produce clear guidelines on uncertainty impacts, to support clinical decisions on robust treatment methods, to aid in the optimization of verification approaches and …

Brachytherapy

The following are descriptions of several brachytherapy research projects our medical physicists are currently pursuing: Deep Learning Tools for Automated Segmentation and Treatment Planning In Brachytherapy We have developed in-house deep learning based segmentation tools for HDR prostate brachytherapy that outperform commercial alternatives in accuracy. Ongoing research is focused on improving model performance and extending …

Adaptive Radiotherapy

The following are descriptions of several adaptive radiotherapy research projects that our medical physicists are currently pursuing: MRI-guided Adaptive Radiation Therapy MRI-guided radiation therapy provides a method by which we are able to observe daily changes in the patient’s internal anatomy. This can be caused by many factors, ranging from reduction in tumor size to …

The Morris Lab

Last updated: In Situ Tumor Vaccination In situ tumor vaccination is a therapeutic strategy that seeks to convert a patient’s own tumor into a nidus for enhanced presentation of tumor-specific antigens in a way that will stimulate and diversify an anti-tumor T cell response. Radiation therapy elicits an anti-tumor effect through induction of DNA damage in …
