Summary of Content

This module encompases the physical principles and concepts relating to the use of radiation in the detection, diagnosis and management of malignant disease. It introduces students to the routine range of radiotherapy equipment to be found within the modern radiotherapy department in a global context. It also provides a comprehensive and applied approach to the role of imaging systems in the detection, staging and management of malignant disease, treatment planning, and verification and quality assurance procedures.
