Abstract

In multi-slice spiral CT, z-sampling has a great effect on image quality, dose and speed. In our work, we explore using sparse detectors of various designs in multi-slice spiral CT. These designs have fewer detector elements as compared to a regular detector. Or alternatively, they have the same number of detectors but provide more axial coverage for greater scanning speed of longer objects. The sparser detector elements also affect the reconstruction in a similar manner as z-sampling does. To account for the missing detector elements we interpolate the acquired data to simulate a full detector. We apply both bilinear interpolation and directional interpolation and compare them. We also report the quality of the reconstruction and scan speed for each detector pattern.
