HIGH DENSITY FORWARD PROJECTOR FOR SPATIAL RESOLUTION IMPROVEMENT FOR MEDICAL IMAGING SYSTEMS INCLUDING COMPUTED TOMOGRAPHY

摘要

A medical imaging apparatus, processing device or specialized circuit can include an input interface to input scan data of a medical image scan of a target object, a processor to generate an output image from the input scan data, and an output interface to output the output image to, e.g., a display. The processor can execute a first reconstruction of the scan data to obtain an intermediate image of the target object, a high-density forward projection of the intermediate object to obtain generated data, a sinogram updating using both of the generated data and the scan data to obtain a high-resolution sinogram, and a second reconstruction based on the high-resolution sinogram to obtain an output image.
