Introduction Medical practitioners have traditionally measured the body s size and shape by hand to assess health status and guide treatment. Now 3D body-surface scanners are transforming the ability to accurately measure a person s body size shape and skin-surface area Treleaven Wells 2007 Boehnen Flynn 2005 . In recent years technological advances have enabled diagnostic studies to expose more detailed information about the body s internal constitution. MRI CT ultrasound and X-rays have revolutionized the capability to study physiology and anatomy in vivo and to assist in the diagnosis and monitoring of a multitude of disease states. External measurements of the body are more than necessary. Medical professionals commonly use size and shape to production of prostheses assess nutritional condition developmental normality to analyze the requirements of drug radiotherapy and chemotherapy dosages. With the capability to visualize significant structures in great detail 3D image methods are a valuable resource for the analysis and surgical treatment of many pathologies.
