This gain in SNR can be pushed even further locally by designing region\u2010focused dense receive arrays. The temporal lobes are particularly interesting to neuroscientists as they are associated with language and concept recognition. Our main goal was to maximize the SNR in the temporal lobes and provide high\u2010acceleration capabilities for fMRI studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We designed and developed a 32\u2010channel receive array made of non\u2010overlapped hexagonal loops. The loops were arranged in a honeycomb pattern and targeted the temporal lobes. They were placed on a flexible neoprene cap closely fitting the head. A new stripline design with a high impedance was proposed and applied for the first time at 11.7T. Specific homebuilt miniaturized low\u2010impedance preamplifiers were directly mounted on the loops, providing preamplifier decoupling in a compact and modular design. Using an anatomical phantom, we experimentally compared the SNR and parallel imaging performance of the region\u2010focused cap to a 32\u2010channel whole\u2010brain receive array at 11.7T.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The experimental results showed a 1.7\u2010time higher SNR on average in the temporal lobes compared to the whole brain receive array. The g\u2010factor is also improved when undersampling in the antero\u2010posterior and head\u2010foot directions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A significant SNR boost in the temporal lobes was demonstrated at 11.7T compared to the whole\u2010brain receive array. The parallel imaging capabilities were also improved in the temporal lobes in some acceleration directions.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mrm.30274","type":"journal-article","created":{"date-parts":[[2024,9,2]],"date-time":"2024-09-02T06:46:05Z","timestamp":1725259565000},"page":"433-447","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A 32\u2010channel high\u2010impedance honeycomb\u2010shaped receive array for temporal lobes exploration at 11.7T"],"prefix":"10.1002","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6592-5034","authenticated-orcid":false,"given":"Paul\u2010Fran\u00e7ois","family":"Gapais","sequence":"first","affiliation":[{"name":"Paris\u2010Saclay University, CEA, CNRS, NeuroSpin, BAOBAB   Gif\u2010sur\u2010Yvette France"},{"name":"Multiwave Technologies SAS  Marseille France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Luong","sequence":"additional","affiliation":[{"name":"Paris\u2010Saclay University, CEA, Irfu, DACM  Gif\u2010sur\u2010Yvette France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Giacomini","sequence":"additional","affiliation":[{"name":"Paris\u2010Saclay University, CEA, CNRS, NeuroSpin, BAOBAB   Gif\u2010sur\u2010Yvette France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jules","family":"Guillot","sequence":"additional","affiliation":[{"name":"Paris\u2010Saclay University, CEA, CNRS, NeuroSpin, BAOBAB   Gif\u2010sur\u2010Yvette France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elias","family":"Djaballah","sequence":"additional","affiliation":[{"name":"Paris\u2010Saclay University, CEA, CNRS, NeuroSpin, BAOBAB   Gif\u2010sur\u2010Yvette France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3146-6079","authenticated-orcid":false,"given":"Shajan","family":"Gunamony","sequence":"additional","affiliation":[{"name":"Imaging Centre of Excellence University of Glasgow  Glasgow UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4170-777X","authenticated-orcid":false,"given":"Son","family":"Chu","sequence":"additional","affiliation":[{"name":"Imaging Centre of Excellence University of Glasgow  Glasgow UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6104-2138","authenticated-orcid":false,"given":"Sajad","family":"Hosseinnezhadian","sequence":"additional","affiliation":[{"name":"Multiwave Technologies SAS  Marseille France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2667-9387","authenticated-orcid":false,"given":"Alexis","family":"Amadon","sequence":"additional","affiliation":[{"name":"Paris\u2010Saclay University, CEA, CNRS, NeuroSpin, BAOBAB   Gif\u2010sur\u2010Yvette France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,9]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.29391"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.25677"},{"key":"e_1_2_8_4_1","volume-title":"Proceedings of the 32nd Annual Meeting of the International Society of Magnetic Resonance in Medicine (Toronto, CA)","author":"Amadon A","year":"2023"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10334\u2010023\u201001063\u20105"},{"key":"e_1_2_8_6_1","volume-title":"Proceedings of the 33rd Annual Meeting of the International Society of Magnetic Resonance in Medicine (Singapore)","author":"Mauconduit F","year":"2024"},{"key":"e_1_2_8_7_1","doi-asserted-by":"crossref","unstructured":"BoulantN MauconduitF GrasV et al.First in vivo images of the human brain revealed with the Iseult 11.7T MRI scanner.2024. doi:10.21203\/rs.3.rs\u20103931535\/v1","DOI":"10.1038\/s41592-024-02472-7"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2011.05.010"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2016.11.031"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.87.24.9868"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nec.2010.11.001"},{"key":"e_1_2_8_12_1","author":"Cleveland Clinic","year":"2023","journal-title":"Aphasia: Types, Causes, Symptoms & Treatment.
