The Major Advantage of IMRT Over Conventional 3D CRT Treatment

The major advantage of IMRT over conventional 3D CRT treatment techniques is that:

A) IMRT delivers a higher dose to the surrounding structures.
B) IMRT delivers a uniform dose to both tumor volume and surrounding structures.
C) IMRT delivers a variable tumor dose from each treatment field.
D) IMRT delivers a conformal dose of varying beam intensities.
