3-D Conformal Radiation Therapy
"Three dimensional" means the treatment is based on a CT scan
of the region to be treated, so we can use computer software to determine
how the patient will appear from any desired direction. This lets the
Radiation Therapy team choose optimal approaches for the radiation beams.
"Conformal" means that the beams are custom shaped to maximize
the treatment of the disease while minimizing the radiation given to healthy tissues.
A sophisticated device (multileaf collimator) is used to block radiation
from entering areas that need protection.
