However, it is clearly unpractical for most biomedical research laboratories. In this paper, polychromatic X-ray fluorescence computed tomography with sheet-beam geometry is tested by Monte Carlo simulation. First, two phantoms (A and B) filled with PMMA are used to simulate imaging process through GEANT 4. Phantom A contains several GNP-loaded regions with the same size (10 mm) in height and diameter but different Au weight concentration ranging fro","authors_text":"Biao Wei, Luzhen Deng, Mianyi Chen, Peng He, Shanghai Jiang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.med-ph","submitted_at":"2017-03-04T13:41:57Z","title":"Monte Carlo Simulation for Polychromatic X-ray Fluorescence Computed Tomography with Sheet-Beam Geometry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.01455","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":"sha256:826df2292addc9e869ebbddeff171a70d54e3ef2c9014c78cfe50a58587f1c74","target":"record","created_at":"2026-05-18T00:49:30Z","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":"5ee8f6da54386e987c5b3a2678da227664d0eecc6338a1067bcfb1ede8a84acc","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.med-ph","submitted_at":"2017-03-04T13:41:57Z","title_canon_sha256":"ebd843aa86b4e93f828d5589be834352b095bd52cfda46875767d996376b8464"},"schema_version":"1.0","source":{"id":"1703.01455","kind":"arxiv","version":1}},"canonical_sha256":"c5880dcb0adf385ea017b8cb6369b4a3fc44dab4a16f7a38f1056d3f45b722f3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c5880dcb0adf385ea017b8cb6369b4a3fc44dab4a16f7a38f1056d3f45b722f3","first_computed_at":"2026-05-18T00:49:30.645007Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:49:30.645007Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Z0+us05pVVKwMTmWZwycMESbKMW462tqQVa719fEjIv0uK7bIITLjVkc0HqYf8OFuP772DcNaP5yHz+TrSj0Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:49:30.645523Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.01455","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:826df2292addc9e869ebbddeff171a70d54e3ef2c9014c78cfe50a58587f1c74","sha256:e4042bb35db9638e1fa8ba8579d6e40ce03364b00004a9d87a9c3fbffb23c533"],"state_sha256":"ee728fd68e6097a5ea6ef918a0560b102f1e9e38f0cf99ea9344cc2720e2ac05"}
