A comparative study of popular interpolation and integration methods for use in computed tomography
We compare various popular methods available for projection and backprojection in CT. Assuming linear rays and a simple density integration along them, we consider both line- and ...

Dynamic Imaging and Tracer Kinetic Modeling for Emission Tomography Using Rotating Detectors
— When performing dynamic studies using emission tomography the tracer distribution changes during acquisition of a single set of projections. This is particularly true for some ...
