Rad Chat

Naman Julka-Anderson and Jo McNamara catch up Igor Bessières and Mathieu Gonod. MapRT helps to make treatments fast, easy and safe. It uses SGRT to deliver a “clearance map”, which planners use to check which beams are deliverable during plan creation. In this podcast episode, Medical Physicists Igor Bessières and Mathieu Gonod from Centre Georges-François Leclerc share their firsthand experience with this innovative technology and its impact on treatment planning. 
 
To use this podcast as CPD, look at these reflection points: 
1) reflect on Igor and Mathieu’s experience of gathering data to showcase the benefits of new technology.
2) consider the barriers and enablers to dynamic trajectory radiotherapy.
3) find out more about the SGRT community, resources and videos about their technology: https://sgrt.org/
