These findings highlight the potential of DFAM as a promising solution to advance low-field MRI reconstruction, particularly in resource-constrained or underdeveloped clinical settings.","authors_text":"Dong Liang, Qiegen Liu, Xin Xie, Yu Guan, Zhuoxu Cui","cross_cats":["cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.med-ph","submitted_at":"2025-07-09T12:30:06Z","title":"Diffusion-Assisted Frequency Attention Model for Whole-body Low-field MRI Reconstruction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.17764","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:f9241c1e6abc4376f0b212cd1eb38aa15d1b0499bdc7b6fdb0fc5d07dba23b23","target":"record","created_at":"2026-07-05T11:42:34Z","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":"c0f704178f2264ec2267e0d2962d242f0b87efda43b5d6b713165ba0e9d2e287","cross_cats_sorted":["cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.med-ph","submitted_at":"2025-07-09T12:30:06Z","title_canon_sha256":"1c083cb49982e41b62a2726048d8487fb2e1d8b268be5950681989522605b792"},"schema_version":"1.0","source":{"id":"2507.17764","kind":"arxiv","version":1}},"canonical_sha256":"e5d5c195956a964702959569cd23c4a43a667f02eab45093c801cc7aa20bef03","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e5d5c195956a964702959569cd23c4a43a667f02eab45093c801cc7aa20bef03","first_computed_at":"2026-07-05T11:42:34.627643Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:42:34.627643Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RleFFhDuazz2jem2zRtoylCwZHfbznDFwWciQ5Wo20OajFxhZ1RRil6vN8z8FnsPCKQZtn5D/vfNhq4nk9/PBg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:42:34.628293Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.17764","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f9241c1e6abc4376f0b212cd1eb38aa15d1b0499bdc7b6fdb0fc5d07dba23b23","sha256:847ede0cba4f99e2f465f24a830e0f9cb4a3fd81b39bacc7f3ab195a87004be8"],"state_sha256":"9510612663771a2e43bff506e1d2ffcca961cb79be3bba644bb47dbb55101977"}
