WebJul 27, 2016 · After scaling, the attenuation-correction factors are generated by integration (forward projection) along each line of response in the emission data. In practice, however, the CT images may be acquired with intravenous or oral contrast present and they may contain artifacts because of truncation of the arms and patient respiration. WebForward propagation refers to the forward data process for inference presented in …

WebImage reconstruction in CT is a mathematical process that generates tomographic images from X-ray projection data acquired at many different angles around the patient. Image reconstruction has fundamental impacts on image quality and therefore on radiation dose. WebForward Projection. The forward projections of the predicted image are then used to … WebFeb 9, 2024 · This project is forward projection of equidistance fan-beam CT system using Siddon's algorithm.
