Figure 5. — Example results from FBSEM-Net.^52,53 FBSEM-Net offers improved image quality when reconstructing data equivalent to just 2 min of scanning time, with image quality competitive to the reference reconstruction from ~15 times more data (30 min of data). The results shown are for “test time” reconstructions (i.e. for reconstruction of data not included in the training of FBSEM-Net). OSEM, ordered subsets expectation maximisation; FBSEM, forward backward splitting expectation maximisation.
