Title: 3D Image (CT/MRI) Guided GYN HDR Brachytherapy: What do clinical medical physicists need to know?

Date & Time: Thursday, May 4th at 12:30 pm EDT

 

A new international guideline of ICRU Report #89 for 3D image-guided gynecological brachytherapy has been published as a replacement of old ICRU report #38 which is based on X-ray images and includes the well-known, four reference points of Point A, B, rectal point, and bladder point. In this talk, the new and basic aspects of 3D-Image Guided (IG), GYN HDR that medical physics need to be clinically aware of, will be reviewed and summarized based upon ICRU Report #89 that include;

1) Commissioning intracavitary/interstitial applicators and TPS

2) Commissioning/testing 3D image (CT/MRI) scan protocols ...

Speaker: Michael Fix, PhD Deputy Head of the Division of Medical Radiation Physics at Inselspital - University Hospital Bern, Switzerland

Title: Photon Dose Calculation in External Beam Radiotherapy Part I & II

 

Date & Time: Tuesday, April 11th at 1:00 pm ET

The first webinar “Dose Calculation Algorithms in Teleradiotherapy”:

This webinar presents the basic concepts of correction based and model based dose calculation algorithms. For the correction based algorithm a typical parameterisation is introduced and the calculation of the dose distribution in water for arbitrary field sizes is shown. Further correction factors lead then to the dose estimation in the patient. The second part presents the basic approach for deterministic model based dose ...

You are invited to the next FREE WePassed live Webinar in the series! This is a joint webinar, hosted by both WePassed and VisionRT. Surface Guided Radiation Therapy (SGRT) is a new technique that is rapidly becoming a common practice these days. So you get to learn about a new technology AND prepare yourself to answer board questions on this new topic (and given the spread of this technology now, you ARE likely to be questioned on this topic). And it's free. What's not to like? So please join the webinar and come with lots of questions that you want to be answered on this topic.

Title: TG-142: Tips, tricks, and modern techniques

Date & Time: Thursday, March 9th, 2017 at 12:00 PM ET

Speaker: Justus Adamson, Assistant Professor of the Division of Radiation Physics and Department of Radiation Oncology at Duke University Medical Center.


TG-40 (1994) is over 20 years old now and TG-142 (2009) is over 7 years old. Many new developments have been introduced since these reports were published. Ion chambers, solid water slabs, and films will likely be with medical physicists for a long time but we now also have many new devices and softwares that can help us do the tests in these reports more efficiently. Dr. Justus Adamson from Duke University will provide an ...

Title: Shielding and NCRP 151

Date & Time: Wednesday, February 22 at 6:30 pm ET

Learn or refresh your knowledge on NCRP 151 from the AUTHOR of the report! The objectives of this presentation are to review what is involved in designing radiation shielding for radiation therapy treatment vaults.  We start with a review of who regulates radiation and how those regulations are formulated. Distinctions between public and occupational limits and controlled and uncontrolled areas are presented. Primary and secondary barrier calculations for therapy x-ray beams are the principal focus, although special concerns for HDR and proton machines are discussed. Shielding materials and related characterizations (e.g., TVLs) are presented.  Examples are presented and special concerns related to mazed and mazeless room layouts, their impact on door ...

Title: What you need to know about medical linacs: Part 2

Date: Thursday, February 16th at 6:30 PM ET

Speaker: Timothy J. Waldron, M.S. from the Medical Physics Group and Radiation Oncology Department at the University of Iowa Hospital & Clinics

Tim Waldron, the linac engineer and the medical physicist, is back with the second lecture on how linac works. Those of you who attended his first webinar recently, or watched the recording in our library, know what insights you can learn from him on the inner workings of the ...

This Webinar has been rescheduled due to technical difficulties. We apologize for the inconvenience and hope you will able to join us next week!

To many medical physicists, ADCL is like a black box. You send them your equipments and they spit out the calibration reports for you. Ever wonder what happens inside the black box? Join us on this webinar given by Kim Working, who is the president of K&S Associates, one of the three ADCLs in the US. Kim will talk about how the calibration chain works from NIST down to your devices and what happens when your devices (chambers, electrometers, survey meters) are sent to the ADCL. Kim will also share his unique experience in this area and share problems that they see with device calibration. You will likely know more about ADCL after listening to this talk than ...

Date: December 15, 2016 6:30 PM ET

Speaker: Timothy J. Waldron, M.S. from the Medical Physics Group and Radiation Oncology Department at the University of Iowa Hospital & Clinics

 

Tim Waldron is one the very few people qualified to give a webinar on the inner workings of a medical linac to a medical physics audience. Tim is a clinical medical physicist at the University of Iowa but in his previous life, he was a linac engineer so, in addition to knowing how to clinically use a linac, Tim actually knows how to fix it! He has ...
