Patient-Adaptive Reconstruction and Acquisition Dynamic Imaging with Sensitivity Encoding (PARADISE), is a highly accelerated non-gated dynamic imaging scheme that enables artifact-free imaging while providing performance guarantees on achievable SNR and spatio-temporal resolution. In addition to parallel imaging, the method gains acceleration from a sparse spectral support model (in x-y-f space) that is adapted to the imaged subject; hence it is doubly accelerated. It uses the support information and coil sensitivities to adapt both the acquisition and reconstruction; hence it is also doubly adaptive. Results demonstrate the superior spatio-temporal resolution and SNR of PARADISE compared to non-gated TSENSE.
