The EPCOSI sequence acquires 2-spatial and 2-spectral dimensions in a single scan. The kx and t2 dimensions are acquired simultaneously, but the ky and t1 dimensions are acquired indirectly. By under-sampling the indirect spectral and spatial dimensions and reconstructing with Maximum Entropy, we have shown that a 4x reduction factor can be used to reduce the scan time to a clinically acceptable 5 minutes with equivalent spatial and spectral results.
