Prostate cases ( Planed By £ ohn )
GTV=Prostate+seminal vesicles, PTV=PTV+10mm margin (5 mm at rectum)
Isocenter is center of PTV, and ICRU point (Dose indication point) is 7mm ventral side.
He set the Jaw of Port 4 ( Rectangular Rotational Port , Not Dynamic Conformal!!) as just size of PTV width, and Length was set PTV+10mm.
He set MLC very near the edge of PTV shape. This is his way to plan.
