In radiation therapy, how do you know you’re giving patients the right amount of radiation?

The radiation oncology team performs a lot of checks before, during and after treatment to make sure treatments are delivered as precisely and safely as possible. Before treatment, the patient will be set up in a way that will hold them still for every treatment, and their images are used to create a custom-made treatment plan for their body and their disease. During treatment, more imaging is used to make sure they’re positioned precisely where they need to be. The medical physicist(s) on the team will be doing behind-the-scenes checks during the whole process to make sure the treatment plan is correct, the machine is operating as it should, and the radiation dose delivered matches the plan.
