Radiation therapy in which a small container of radioactive material is implanted in the body, in or near the cancerous tumor.
- Radiation therapy, stereotactic
The use of a number of precisely aimed beams of ionizing radiation, each coming from a different direction and meeting at a specific point, to deliver radiation treatment to that spot.
- Radiation therapy, targeted
A procedure that uses computers to create a 3-dimensional picture of the tumor in order to target the tumor as accurately as possible and give it the highest possible dose of radiation while sparing normal tissue as much as possible. It is also known as 3-D conformal (or conformational) radiation therapy. Conventional radiation therapy directs […]
