- W4311557157 abstract "This Special Report summarizes the 2022 AAPM Grand Challenge on Deep-Learning spectral Computed Tomography (DL-spectral CT) image reconstruction. The purpose of the challenge is to develop the most accurate image reconstruction algorithm for solving the inverse problem associated with a fast kVp switching dual-energy CT scan using a three tissue-map decomposition. Participants could choose to use deep-learning (DL), iterative, or a hybrid approach. Test phase submission were received from 18 research groups. Both the winning and second place teams had highly accurate results where the RMSE was nearly zero to single floating point precision. Results from the top ten also achieved a high degree of accuracy; and as a result this special report outlines the methodology developed by each of these groups. The DL-spectral CT challenge successfully established a forum for developing image reconstruction algorithms based on deep-learning that address an important inverse problem relevant for spectral CT." @default.
