Sm. Tozer-loft et al., An improved technique for comparing Gamma Knife dose-volume distributions in stereotactic radiosurgery, PHYS MED BI, 44(8), 1999, pp. 1905-1919
A function derived from the geometry of brachytherapy dose distributions is
applied to stereotactic radiosurgery and an algorithm for the production o
f a novel dose-volume histogram, the Anderson inverse-square shifted dose-v
olume histogram (DVH), is proposed. The expected form of the function to be
plotted is checked by calculating its value for single focus exposures, an
d its application to clinical examples of Gamma Knife treatments described.
The technique is shown to provide a valuable tool for assessing the adequa
cy of radiosurgical plans and comparing and reporting dose distributions.
