Physics Colloquium Schedule:Spring 2024
 

March 15, 2024:

Dr. Ignacio Romero Stanford University

Automated Contouring, Treatment planning, and Quality Assurance of
Volumetric Modulated Arc Therapy Craniospinal Irradiation (VMAT-CSI)

Abstract:  Craniospinal irradiation (CSI) is a main form of treatment for nervous system tumors that have
spread along the brain and spine. The treatment covers a large area of the body and achieving a
uniform dose across this extensive region can be technically challenging. The conventional
treatment technique for these tumors is 3D CSI which is prone to error due to the complexity
of the treatment planning and delivery setup. Unlike other modern CSI techniques like
TomotherapyTM and Proton Beam Scanning (PBS), Volumetric Modulated Arc Therapy
(VMAT) offers a robust and accessible treatment technique for CSI. However, the treatment
planning and plan check requires extra attention from physicians, dosimetrists, and physics.
Automation tools like auto-planning and auto-segmentation can help alleviate the time and
effort required for these cases without sacrifice of plan quality and patient safety. In this talk, I
will present an overview to the contouring, treatment planning, and quality assurance of
VMAT-CSI as well as a brief introduction to the automation tools that have helped optimize
its workflow at Stanford University.

 

 

Physics Colloquium Schedule:Spring 2023

The Physics Department hosts a regular colloquium series on Fridays at 3PM in room McL 162, and participates with the Math Department in the Functional Analysis and Mathematical Physics (FAMP) Interdepartmental Research Group meetings.
