摘要
A computer system and method solve the problem of getting a useful three dimensional representation of an object like the spine using a small amount of data. This is done by gathering and combining three dimensional data in the form of computer tomography (CT) scans of a patient's bones with two dimensional data consisting of CT scout images (or scouts), which are digital two dimensional X-ray images that can be produced by a CT scanner. The main features of spinal deformation are captured by combining the two dimensional data from CT scouts and the three-dimensional information from the CT scans using simple modeling of vertebrae. Scouts are usually used to monitor CT scan acquisition. Here, they are also used as an essential source of data.
