Using our current planning margins to the prostate (6 mm |
|
posterior and 8 mm elsewhere) and pelvic lymph nodes (5 |
|
mm uniform), we found that aligning daily images to the |
|
pelvic bones would require a planning margin of the |
|
prostate greater what we used clinically. Aligning to the |
|
prostate soft tissue, a planning margin of 5 mm to the |
|
pelvic lymph nodes is adequate while the planning margin |
|
to the prostate can be further reduced. With smaller |
|
planning margins or greater magnitudes of the prostate |
|
displacement, the proposed adaptive planning method may |
|
be beneficial. After comparing three commonly available |
|
multi-leaf collimator (MLC) leaf widths of 2.5 mm, 5 mm, |
|
and 10 mm, we found that the use of a leaf width of 5 mm |
|
was adequate for the proposed adaptive method to |
|
compensate for the prostate movement in the longitudinal |
|
direction. |
