It relies on $k$-space undersampling and multiple receiver coils with complementary sensitivity profiles in order to reconstruct a full Field-Of-View (FOV) image. The performance of parallel imaging mainly depends on the reconstruction algorithm, which can proceed either in the original $k$-space (GRAPPA, SMASH) or in the image domain (SENSE-like methods). To improve the performance of the widely used SENSE algorithm, 2D- or slice-specific regularization in the wavelet domain has been effi","authors_text":"Jean-Christophe Pesquet, Lotfi Chaari, Philippe Ciuciu, S\\'ebastien M\\'eriaux, Solveig Badillo","cross_cats":["cs.CV","physics.med-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2011-03-17T23:11:58Z","title":"4D Wavelet-Based Regularization for Parallel MRI Reconstruction: Impact on Subject and Group-Levels Statistical Sensitivity in fMRI"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1103.3532","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6331bfee19dd21b9bb4ec7028ea35d3087ce516b2a14c1d5d0aa9e0d621dd824","target":"record","created_at":"2026-05-18T04:26:32Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c39b09c6611bc79fbfeef41d45277123a061d41c2e033f088cdb6ba6241459a8","cross_cats_sorted":["cs.CV","physics.med-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2011-03-17T23:11:58Z","title_canon_sha256":"a7261239f306e24495a9b03d450b01d7d3150c48555fa2deb6629886558ea61c"},"schema_version":"1.0","source":{"id":"1103.3532","kind":"arxiv","version":1}},"canonical_sha256":"c2eb15963b1aef20948bd1d042178cf602a1d4818fa36b7cd3d738b05fe0d67d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c2eb15963b1aef20948bd1d042178cf602a1d4818fa36b7cd3d738b05fe0d67d","first_computed_at":"2026-05-18T04:26:32.442106Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:26:32.442106Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jilRVsaLl0VmpoJh2qkwzoxZbFsVB0kMwEZtsUKuK4PK994rbdd+R0K6wDEuVKRPesY+QOIQd3pA+fWinR55DA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:26:32.442661Z","signed_message":"canonical_sha256_bytes"},"source_id":"1103.3532","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6331bfee19dd21b9bb4ec7028ea35d3087ce516b2a14c1d5d0aa9e0d621dd824","sha256:09b9876da7d777fcfb8752d20accb234f6596cfc92701db4db67fc54fa419c6f"],"state_sha256":"303723660c3ca49238cc20e17ed11d6773a7c4bbdaa475b447319a14f05fb26c"}
