Methods and apparatus for adaptive interpolation reduced view CT scan

摘要

One aspect of the present invention is a method for computerized tomographic (CT) imaging of an object. One embodiment of the method includes scanning an object with a CT imaging system to acquire views that include projection samples of an object; interpolating the acquired views within a selected view range to produce interpolated views; weighting the interpolated views to compensate for the interpolation; weighting the acquired views; and filtering and backprojecting the weighted, interpolated views and the weighted acquired views to generate an image of the object. View aliasing artifacts are reduced by this embodiment without using conjugate samples.
