simulation
Planning procedure using CT imaging to determine patient positioning and beam arrangements for radiation therapy.
Full Definition
The simulation process involves acquiring detailed three-dimensional images of the patient in the exact treatment position to design the radiation therapy plan. During simulation, patients are positioned using immobilization devices, and CT scans are obtained to define target volumes and organs at risk. This step is essential for accurate dose calculation and reproducible daily treatments.
Usage
Usage note: In radiation oncology, specifically refers to the planning CT procedure, not general modeling.
In Context
- "The patient is scheduled for simulation tomorrow with a custom thermoplastic mask." — Appointment scheduling
