souhrn: Radiation dose from medical diagnostic radiology such as CT examination has the potential to cause harm if the cumulative dose from successive procedures adds to a significant amount. Detriment is estimated by determining the effective dose (E) a quantity that requires knowledge of the amount of energy deposited in each of the specific organs and tissues (the organ doses) that are used to determine E. Thus, accurate human anatomy models is important in more accurate estimation of the effective dose.
Mathematical models of human anatomy has been used in calculating the effective dose.
In recent years, there has been increasing interests in constructing realistic human anatomy model from medical data for effective dose calculation.
So far, few hybrid anatomy models have been achieved. Existing anatomy models have been constructed using semi-automatic or supervised segmentation methods. However, the process of segmenting all of the tissues in hundreds of images is extremely time consuming. This leads to the challenge of a practical full-body CT segmentation framework.
