From: A dosimetric comparison of four treatment planning methods for high grade glioma
A sample Dose Volume Histograms (DVH) of normal brain dose with two different plans. Although the Integral Dose to the brain according to these to DVH's is the same (15.4 Gyxcm3 × 1000), it is obvious that these histograms are different in both high and low dose areas. The dose received by 10% of the brain volume (D10) and 90% of the brain volume (D90) can describe more accurately such a difference. Abbreviation: NA-not applicable. SD-Standard Deviation.
