Figure 1 Comparison of three dimensional conformal radiation therapy (A) and intensity modulated radiation therapy (B) treatment plans. The yellow line denotes the area that is receiving the prescription dose. The outer blue line denotes 90% of the prescription dose. Notice in (B) the yellow line conforms to the prostate (red) and does not enter into the bladder or rectum as it does in (A), demonstrating the increased dose given to the bladder and rectum with 3DCRT (A). 3DCRT: Three dimensional conformal radiation therapy.
