WebStep 1) Your CT-simulation and MRI scan are fused together so that they are exactly superimposed. Step 2) The radiation oncologist draws his target. This is called “contouring”. On each CT / MRI slice, he draws a line around the target he wants treated. This would normally be a line around prostate gland.
