2016_Imaging for Physicists

Why should medical physicists in RT worry about imaging technology?

• Radiotherapy asks other questions than standard diagnostics: – Not if a patient has cancer, but where the tumor starts and ends

• Radiotherapy poses specific demands on imaging – Patient positioning

– High resolution imaging – Geometrical accuracy

• The use of MRI poses specific demands on radiotherapy – How to deal effectively with all the images during delineation

– How to deal with conflicting information – How to deal with changes during treatment
