OAR delimitation
Prostatic urethra:
a 10 mm urinary catheter should be
contoured with aereated gel inside to avoid distension of the
urethra. Delineation of the outer contour should be from the
prostatic base to 5-10 mm below the prostatic apex.
Rectum:
contouring of the outer wall is the minimum
requirement. Contouring of the inner and outer walls is more
correct for analysis of late damage.
Penile bulb and
Neurovascular bundles:
remains under study.
