{"doi":"10.3390/s21186000","title":"Evaluation of 8-Channel Radiative Antenna Arrays for Human Head Imaging at 10.5 Tesla","abstract":"For human head magnetic resonance imaging at 10.5 tesla (T), we built an 8-channel transceiver dipole antenna array and evaluated the influence of coaxial feed cables. The influence of coaxial feed cables was evaluated in simulation and compared against a physically constructed array in terms of transmit magnetic field (B1+) and specific absorption rate (SAR) efficiency. A substantial drop (23.1% in simulation and 20.7% in experiment) in B1+ efficiency was observed with a tight coaxial feed cable setup. For the investigation of the feed location, the center-fed dipole antenna array was compared to two 8-channel end-fed arrays: monopole and sleeve antenna arrays. The simulation results with a phantom indicate that these arrays achieved ~24% higher SAR efficiency compared to the dipole antenna array. For a human head model, we observed 30.8% lower SAR efficiency with the 8-channel monopole antenna array compared to the phantom. Importantly, our simulation with the human model indicates that the sleeve antenna arrays can achieve 23.8% and 21% higher SAR efficiency compared to the dipole and monopole antenna arrays, respectively. Finally, we obtained high-resolution human cadaver images at 10.5 T with the 8-channel sleeve antenna array.","journal":"Sensors","year":2021,"id":181438,"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":16,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9571,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":386563,"name":"Lance DelaBarre","orcid":null,"position":1,"is_corresponding":false},{"id":449800,"name":"Matt Waks","orcid":"0000-0003-1743-8888","position":2,"is_corresponding":false},{"id":471774,"name":"Young Woo Park","orcid":"0000-0001-8737-6278","position":3,"is_corresponding":false},{"id":320267,"name":"Russell Lagore","orcid":"0000-0003-1950-1828","position":4,"is_corresponding":false},{"id":393369,"name":"Steve Jungst","orcid":"0000-0001-8374-7924","position":5,"is_corresponding":false},{"id":393372,"name":"Yiğitcan Eryaman","orcid":"0009-0006-7880-9872","position":6,"is_corresponding":false},{"id":699421,"name":"Se‐Hong Oh","orcid":"0000-0001-9771-8382","position":7,"is_corresponding":false},{"id":256599,"name":"Kâmil Uǧurbil","orcid":"0000-0002-8475-9334","position":8,"is_corresponding":false},{"id":320269,"name":"Gregor Adriany","orcid":"0000-0002-6428-9005","position":9,"is_corresponding":false},{"id":492738,"name":"Myung Kyun Woo","orcid":"0000-0002-6440-3963","position":0,"is_corresponding":true}],"reference_count":32,"raw_metadata":null,"created_at":"2026-07-18T23:48:05.146883Z","pmid":"34577210","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
