Criteria for intensity‐modulated radiation therapy plan acceptance^a

Structure		Physical end point $\mathit{(}\%\mathit{)}$
PTV	$D_{max}$	$<110$
	$D_{min}$	$\ge 87$
	$D_{95}$	$\ge 95$
	$V_{95}$	$\ge 95$
Rectal wall	$D_{max}$	$\le 106$
	$V_{79}$	$\le 45$
	$V_{40}$	$\le 90$
Bladder wall	$D_{mean}$	$\le 60$
Urethra	$D_{max}$	$\le 100$

^aThese are the criteria used for 50.4 Gy prostate cases only at Memorial Sloan–Kettering Cancer Center.

PTV = planning target volume; $D_{max}=$ maximal dose; $D_{min}=$ minimal dose; $D_{95}=$ dose covering $95\mathrm{\%}$ volume; $V_{95},V_{79},V_{40}=$ volume receiving $95\mathrm{\%},79\mathrm{\%}$, and $40\mathrm{\%}$ prescribed dose respectively; $D_{mean}=$ mean dose.
