Title: An introduction on MRI-based treatment planning

Speaker: Tonghe Wang, PhD 

Date/Time: Wednesday, January 29th at 6pm EDT

About the webinar: Magnetic resonance imaging (MRI)-only radiotherapy treatment planning is attractive since MRI provides superior soft tissue contrast without ionizing radiation compared with computed tomography (CT). The main difficulty in the introduction of MRI-based treatment planning is that MRI images cannot provide material attenuation coefficients which can be easily converted into electron density after calibration for subsequent dose calculation. This webinar will go over the basic physics of CT and MR, and discuss current methods in using MRI for dose calculation.

Title: Novel Uses of SBRT: Treatment of Ventricular Tachycardia

Speaker: Ryan Zielan, MS, RT(T), CMD

Date/Time: Thursday, October 24th 2019 at 6pm EDT


Recently it has been evidenced that ventricular tachycardia (VT) can be treated non-invasively using stereotactic radiotherapy. Utilizing imaging techniques physicians are able to identify and effectively treat patients utilizing external beam radiotherapy. Working collaboratively, cardiologists and radiation oncologists are able to safely deliver single fraction SBRT treatments to a patient in a matter of minutes. The results of these treatments have resulted in drastic reductions in VT events in patients following treatment, resulting in an improved quality of life.

Learning Objectives:

Describe the rationale behind treating patients ...

Title: Valuable aspects of commissioning a flattening filter-free linear accelerator

Speaker: Tucker J. Netherton, DMP

Date/Time: Thursday, October 10th at 6:00 PM EDT 


The Halcyon linear accelerator has many components and features that are unique when compared to conventional linear accelerators. However, medical physics practice guidelines and relevant task group reports explain how to handle output calibration, commissioning, and quality assurance. This webinar focuses on what to consider when commissioning a new linear accelerator and how to characterize important flattening-filter-free beam characteristics.  


About the Speaker: After matriculating into Vanderbilt University’s DMP program in 2012, Tucker J. Netherton developed a deep understanding of medical physics while under the mentorship of Dr. Charles Coffey and Dr. Manuel Morales. In addition, he completed a 2-year clinical residency that was supplemented ...

Title: Electron dose calculation algorithms

Date/Time: Thursday, September 12th at 12:00 pm EDT


Commercial electron Monte Carlo algorithms have become more widely available in recent years, providing increased accuracy over pencil beam algorithms at clinically useful computation times. This webinar reviews electron treatment planning basics and discusses the differences between pencil beam algorithms vs. Monte Carlo algorithms. Additionally, we will discuss validation testing unique to electron Monte Carlo algorithms and changes to clinical planning procedures when transitioning from pencil beam to electron Monte Carlo.

Title: Intra-Operative Radiation Therapy (IORT)

Speaker: Michael Lometti, Msc, DABR Medical Physicist

Date/Time: Monday, April 15th at 1 pm EDT

Intra-Operative Radiation Therapy (IORT) is the use of radiation therapy in the operating room during a surgical procedure.  IORT allows for delivery of high radiation doses to a tumor while sparing skin and nearby organs at risk. The Mobetron, made by IntraOp Medical, Sunnyvale, California, is designed specifically to deliver IORT in an unshielded operating room.  This webinar will give an overview of IORT and the Mobetron and discuss the role of the physicist in implementing an IORT program, acquiring, accepting and commissioning the Mobetron and clinical use of the Mobetron.
