Physics problem in RT

Focus the dose on the target (in space and time)

Dose localization: ability to deliver dose precisely and accurately to a region of interest in the patient → target (improve geometrical dose shaping )

Target definition: - Tumor delineation - Organ Motion - Organ filling - Tumor shrinkage

Imaging – treatment planning - delivery technology

radiation physical properties – technological inventions

The interaction processes of each type of radiation determine → penetration in matter (how much radiation reaches a target) → the amount of dose deposited in the target → Dose conformation around the target (dose to the OARs)
