The Course • Total 60 Credits for the year – – – – – – –
Anatomy (10 credits) Principles and practice of cancer care (10 credits) Radiobiology (5 credits) Radiotherapy treatment planning (10 credits) Radiotherapy treatment simulation (10 credits) Physics for radiation therapy (5 credits) Clinical practice (10 credits)
• The number of hours (with me and on your own) reflects this • The course covers aspects of Physics which apply directly to PPCC, Treatment Planning and Simulation 2
Overview
Summative Assessment – One end of year exam – Answer 4 questions from a choice of 6 over 2 hours • Therefore approximately 25 min per question
– This is the same format as last two year’s JS received so an example of the exam is on the college exams website

Overview
Formative Assessment • There will be two multiple choice tests. One at the end of each term • These questions are designed to test your understanding (rather than knowledge) • Each question will have multiple answers which may or may not be correct. • If you select an incorrect answer, there will be feedback to explain why. • These MC assessments do NOT form part of your end of year grade and you can attempt them multiple times • However it would be in your interest to do the assessment during the scheduled time. 4
Overview
Points to revise from last year • All of it! • In particular the bits that people did badly on in the exam – Electron and photon interactions – don’t get them confused – TAR, PDD– the factors that affect them. • in particular SSD, SAD – i.e. isocentric vs fixed treatments.
– Contrast agents • Barium, gadolinium
– CT • Helical CT • Greyscale values • Pitch
– Different imaging modalities were a bit confused (surprising) 5

Overview
Book list • Handbook Of Radiotherapy Physics: Theory And Practice – Mayles, Nahum, Rosenwald
• The Physics of Radiation Therapy – 4th Edition (3rd is ok too) – Author - Faiz M Khan
• IAEA Physiscs Text book – Student folder and WebCT – Editor - E Podgorask
• Radiotherapy Physics – Williams and Thwaites -
– 2nd ed is in John Stearne – looking a little old now
• The modern technology of radiation oncology – J Van Dyk – Probably a little too mathematical in places
• Since the course covers different topics, there is no one book that covers everything. 7
