The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Image guidance, the way forward for radiotherapy

Uwe Oelfke from the German Cancer Research Center in Heidelberg, explains how image-guided radiation therapy (IGRT) can address one of the key challenges in modern radiotherapy – namely how to deliver a lethal dose of radiation to a tumour while sparing surrounding healthy tissue. The problem is that radiotherapy generally involves directing an invisible beam at an invisible tumour, based on patient images acquired prior to the treatment. Oelfke explains how IGRT involves acquiring additional images of the patient in the treatment position, immediately before or during radiation treatment, ensuring that the beam is precisely targeted at the tumour.
