The importance of fast software for the secondary MU check for Elekta Unity
Physicist Daniela Thorwarth talks to the importance of fast software for the secondary MU check during adaptive treatments with Elekta Unity.
When a patient is on the table and the RT plan is adjusted based on the daily MRI, ensuring the plan’s accuracy from a dosimetric perspective is crucial. Before the patient enters the room, a thorough QA process is performed to verify the plan. This includes a detailed check to confirm its correctness. Plan recalculation typically takes 2-3 minutes, followed by a quick verification of beam angles, number of fields, and monitor units—ensuring all are within a +/- 10% range. An independent dose recalculation is also implemented as a monitor unit check, safeguarding the plan’s integrity
