Try answering aloud, then open the suggested answer. Examiner questions vary.
01 / Is treatment delivered from a diagnostic CT scanner?
No. Planning imaging and treatment delivery have different purposes.
02 / Why define organs at risk?
Planning aims to limit dose to relevant normal tissues.
03 / Why repeat positioning checks?
Accurate reproducible geometry matters.
04 / Is the same prescription suitable for every tumour?
No. It is individualised by the specialist team.
