ABSTRACT
3D medical imaging and measurement systems are used for non-destructive inspection of the body and its component regions in vivo and in vitro. These systems provide 3D data as discrete points, surfaces, or volumes. 3D medical imaging is used for diagnosis, treatment planning, execution and monitoring of interventions, to extract quantitative measurements, to determine if an abnormality is present by comparison with normal controls, to assess change over time, or all of these. This chapter deals with the subjective and objective evaluation of 3D imaging as it is used in diagnostic radiology, anthropometry, radiotherapy, and surgery. Basic principles and evaluation of 3D anthropometry for measurement of body shape and size are reviewed. Rigorous methods for subjective and objective evaluation of 3D images are described with examples from craniofacial surgery and 3D anthropometry. 3D medical imaging systems measure points, surfaces, slices, or volumes in digital data sets.
