Average and standard deviation of the percent coverage of each partially irradiated organ and the correlation coefficient resulting from the exponential regression relating ${\overline{nD}}_{P,O}$ to perimeter.

Organ	Correlation coefficient	Average percent coverage	Standard deviation of percent coverage
Colon	0.94	84	8
Small intestine	0.62	77	21
Heart	0.51	53	19
Ovaries	0.52	40	55
Uterus	0.60	39	53
Lung	0.56	34	11
Esophagus	0.29	32	12
Glandular breast tissue	0.02	31	41
Skina	0.29	26	9
Muscle tissuea	0.63	24	5
Red bone marrowa	0.70	21	4
Bone surfacea	0.67	22	4
Bladder	0.56	9	19

^aAverage and standard deviation of the percent coverage is artificially high because a portion of Frank, Visible Human, and Donna’s actual organ anatomy was truncated when partial-body models were generated.
