Can you explain why we're using 80.5cm for this MU calc?
Why are we doing an ISL correction based on dose rate at 80.5cm? The treatment is performed at 80cm SSD and the dose rate is calibrated to 80cm. What is that extra 0.5cm about?
My good-faith attempt without the ISL correction resulted in answer B, so I know they're expecting people not to know what this concept is about (and they got me).
