{"doi":"10.1109/tbme.2025.3529725","title":"500 MHz Inductive Birdcage RF Coil for Brain MRI: Design, Implementation and Validation","abstract":"OBJECTIVE: We present a 500 MHz inductive birdcage RF resonator for imaging the human brain in an 11.7 T MRI scanner. METHODS: A homogenous circularly polarized transmit field ($\\text{B}_{1}^{+}$) was generated by transmitting power to the resonator through four couplers driven in differential mode and with an incremental 90-degree phase delay. A detailed mechanical and electrical model of the hardware, loaded with different phantoms, was generated and its performance simulated using a finite-difference time-domain method. RESULTS: The head-size inductively coupled birdcage presented a fundamental mode at 500 MHz. MR thermometry maps were in good agreement with heating profiles estimated from simulated SAR maps Conclusion: The model of the hardware was validated through both bench and MRI measurements. SIGNIFICANCE: This validation is important for future analysis of radiofrequency safety and performance at ultra-high field MRI through the prediction of SAR and $\\text{B}_{1}^{+}$ profiles across different human brain models at various positions inside the coil.","journal":"IEEE Transactions on Biomedical Engineering","year":2025,"id":560786,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9584,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":348051,"name":"Jacco A. de Zwart","orcid":"0000-0001-8155-8185","position":1,"is_corresponding":false},{"id":348050,"name":"Peter van Gelderen","orcid":"0000-0001-8117-8270","position":2,"is_corresponding":false},{"id":377593,"name":"Stephen Dodd","orcid":null,"position":3,"is_corresponding":false},{"id":1463158,"name":"Frank Mauconduit","orcid":null,"position":4,"is_corresponding":false},{"id":855938,"name":"Alexandre Vignaud","orcid":"0000-0001-9203-0247","position":5,"is_corresponding":false},{"id":855941,"name":"Nicolas Boulant","orcid":"0000-0003-2144-2484","position":6,"is_corresponding":false},{"id":376206,"name":"Alan P.
