Physical dose conformation

We explore and develop radiation treatment techniques for optimum physical dose conformation to the tumor target volume. Our efforts are focused on proton radiotherapy and advanced photon treatments, as well as on their comparison.

Biological modeling

As a basis for treatment optimization we work on a variety of modeling projects including relative biological effectiveness in proton therapy, outcome models for the relationship between the dose distribution and clinical outcome, and spatial modeling of microscopic disease for gliomas.

IMXT/IMPT

Intensity modulation is crucial both in photonradiotherapy (IMXT) and in proton radiotherapy (IMPT). In particular, we develop robust optimization methods for handling uncertainty in IMPT, direct aperture optimization algorithms, VMAT plan optimization, and multi-criteria planning methods.

4D

We develop concepts and methods to consider the time component in the whole radiotherapy chain, from imaging over planning and optimization to treatment delivery.

Precision

To increase the precision of the dose application we develop new targeting techniques. To increase the accuracy of the dose prediction we perform Monte Carlo simulations. We develop in vivo range verification to enhance the precision of proton treatment delivery.

Optimization projects: opportunities for students and postdocs

Opportunities for students of operations research, math, physics, computer science who are interested in optimizing cancer therapy, especially in radiation oncology. The projects are suitable as PhD thesis projects, or as part of postdoctoral fellowships. Some may also be suitable for MS theses.

Therapy Imaging Program (TIP)

Supported by Federal Share of program income earned by MGH on C06 CA059267

(T. Bortfeld, G. El Fakhri, R. Jeraj)

TIP Mission

To achieve the best proton therapy treatment through advanced imaging.

To support NCI proton therapy clinical trials at MGH and elsewhere using imaging as a biomarker.
