System and method for acquiring three-dimensional data subject to practical constraints by integrating CT slice data and CT scout images
First Claim
1. A computer-implemented method of three-dimensional modeling of objects comprising the steps of:
- collecting two sets of data, each one containing a limited amount of three-dimensional spatial data of a common three-dimensional object, where the amount of data in either set alone is not sufficient to produce an adequate three-dimensional geometric model of the said common object; and
combining these two sets of three-dimensional data to generate a three-dimensional model of said common object.

Abstract
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 (a) a set of 2D computer tomography (CT) slices of a patient'"'"'s bones with (b) a set of 2D CT scout images, 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 integrating these two sets of three-dimensional data, and constructing from them a three-dimensional geometric model of the spinal. Scouts are usually used to monitor CT scan acquisition. Here, they are also used as an essential source of data.

4. A computer system used to improve the geometric modeling of three-dimensional objects by utilizing two complementary sets of three-dimensional data comprising:
-
a computer with a memory, a central processing unit (CPU), and a display monitor; a first data structure resident in said memory and containing a limited amount of three-dimensional data of the shape of a three-dimensional object, where the amount of data in this first data set is not sufficient on its own to allow construction of a satisfactory geometric model of this three-dimensional object; a second data structure resident in said memory and containing a limited amount of three-dimensional data of the shape of the said three-dimensional object, where the amount of data in this second data set is not sufficient on its own to allow construction of a satisfactory geometric model of this said three-dimensional object; and a process executed by the CPU, to construct a three-dimensional model of the said object using both and the three-dimensional data sets. - View Dependent Claims (5)
