Alex had me working on a plan that had two courses of a treatment: the initial plan and the boost plan. He had already finished preparing the QA for the boost and wanted me to complete it for the initial plan. Basically, this entails going into XiO (our treatment planning software) and starting a new QA plan. To perform the QA, we use a bullet phantom that was designed by Alex. This phantom was scanned a long time ago via CT and imported into XiO. Therefore, we just use that bullet phantom and apply the patient’s plan to the phantom.
We then have to rescale the plan so that only one fraction of the treatment is delivered. This number should also match the total amount of monitor units that are delivered to the patient. Furthermore, the total dose delivered (and for each field) should match the patient’s plan.
