Intensity-modulated radiation therapy of prostate cancer

Segmental multileaf collimator (SMLC) shapes of three segments (A, B, C) of the right anterior oblique field from a beam's eye view, generated for the forward SMLC plan. The forward SMLC plan was generated using the UM-Plan software developed at the University of Michigan. The two dominant intraprostatic lesions (DILs) are depicted in lilac (white arrows), and the prostate is depicted in magenta.
