CT SYSTEM WITH SYNTHETIC VIEW GENERATION
First Claim
1. A method for generating an image of a patient including the steps of:
- a) taking a plurality of x-rays of the patient;
b) generating a three-dimensional image of the patient based upon the plurality of x-rays; and
c) generating a projection based upon the three-dimensional image of the patient, wherein the projection includes a plurality of substantially parallel projection lines.

Abstract
A CT scanner system provides projection-like images of a patient volume. After a CT scan is obtained and a three-dimensional model of the patient is created, any synthetic view can be generated by choosing any array of projection lines, e.g. between a point and a surface (a flat plane, curved plane, spherical, etc) or between two surfaces (parallel or not) and summing across the projection lines. The synthetic projections can mimic certain traditional views, such as a ceph scan, Water'"'"'s view, Caldwell'"'"'s projection, etc or can provide a new view that is impossible or impractical with traditional x-ray equipment, such as a perfect parallel projection, or a projection that does not pass all the way through the patient.
