Abstract

Given a definition of spatial resolution that considers two objects as distinguished if the minimum value of the gap is less than 50% of the value at the object position [7], both approaches achieved an improvement of the spatial resolution in the 1D simulation study as visualized in Fig. 1 and 2. If the spatial resolution is considered as the minimum width of two distinguished lines, the first approach using spatially shifted images achieved a spatial resolution of 1.7 mm and the second approach using different sampling points achieved a resolution of 2.6 mm. This is an improvement in comparison to the used low resolution images with a spatial resolution of 2 mm (first approach) and 2.9 mm (second approach).
