Four-Dimensional Radiation Planning
A special type of radiation therapy planning scan that accounts for tumor motion induced by respirations.
Gating
A technique in radiation therapy where the delivery of radiation is synchronized with the patient’s breathing.
Radiation Field
The area exposed to radiation during treatment.
Isodose Lines
Lines on a radiation therapy plan that show areas receiving the same dose of radiation.
Boost
An additional dose of radiation given to the tumor site.
Radiation Dermatitis
Skin irritation caused by radiation therapy. This commonly looks like a sunburn.
Conformal Radiation Therapy
A type of radiation therapy that shapes the radiation beams to match the shape of the tumor.
Image-Guided Radiation Therapy (IGRT)
The use of imaging during radiation therapy to improve the precision and accuracy of treatment delivery.
Treatment Plan
The detailed plan for a patient’s radiation therapy, including the dose and schedule.
Simulation
