摘要：
The present invention is in one embodiment a method of processing projection data collected in a helical scan performed along a helical trajectory relative to an object being scanned. The method includes steps of defining a coordinate system to parameterize the data and generating estimates of projection data not on the helical trajectory by solving ultrahyperbolic equations in the defined coordinate system.
