2010 Jonsson
•
Adequate bulk density sufficient <1.6% accuracy
looked at prostate head & even in lung with air cavity
•
Large (15%) change in assigned density
modest 1-2%
dose change
2016 Juha
•
Dual bulk (water, bone)
vs
homogenous
vs
full conversion
for brain & prostate
•
Homogenous unacceptable errors in certain cases; bone
and soft tissue essential; further heterogeneity improves
accuracy
•
Dual <2% ; heterogeneous model <0.5%
