Dose Volume Histogram (DVH) based (anatomy) - Dose-Volume-Parameters for Target (V 100 , D 90 , ...)

D

100 : the dose that covers 100% of the target volume, what is equivalent the MTD proposed by ICRU report 58 (ICRU 1998); for the case we consider CTV.

D

: the dose that covers 98% of the target volume.

98

D

: the dose that covers 90% of the target volume.

90

V

100 : the percentage of the target volume that receives at least the prescribed dose, which is set to 100%.

V

150 : the percentage of the target volume, which receives at least 150% of the prescribed dose.
