How do doctors stop the radiation therapy from bouncing around inside your body and hitting other organs?

Image guided: Excellent question. Direct radiation is best delivered by image guidance, and tracking limit collateral damage. Your question is about scatter radiation ( radiation bouncing around inside the body); unfortunately, there is no good way of blocking or stopping scatter radiation in the body.

They account for it: Scatter radiation can and does occur, it can be as high as 10-15% of the delivered dose. That scatter must be accounted for in the planning and is mapped in a device called the dose-volume histogram.
