Radiation treatment planning
Radiation Treatment Planning
Radiation Treatment Planning (pronunciation: /ˌreɪdiˈeɪʃən ˈtriːtmənt ˈplænɪŋ/) is a critical step in the process of radiation therapy for cancer treatment. The goal of radiation treatment planning is to maximize the radiation dose to the tumor while minimizing the dose to the surrounding healthy tissues.
Etymology
The term "Radiation Treatment Planning" is derived from the words "radiation" (from Latin radiatio meaning "shining"), "treatment" (from Latin tractare meaning "to handle, manage, deal with"), and "planning" (from Latin planum meaning "flat surface").
Process
The process of radiation treatment planning involves several steps:
- Imaging: This involves the use of imaging techniques such as CT, MRI, or PET scans to identify the location and size of the tumor.
- Dose Calculation: This involves calculating the amount of radiation that will be delivered to the tumor and the surrounding tissues.
- Treatment Delivery: This involves the use of a radiation therapy machine to deliver the planned dose of radiation to the tumor.
