08:15		1174. An Anatomically Shaped 16-channel Receive Array Coil for UHF Shoulder Imaging at 7T View Presentation Video M. May, L. Wessing, O. Kraff, H. Quick University Hospital Essen, Essen, Germany Impact: The prototyping approach simplifies the geometrical decoupling and rendered a receive array with superior efficiency over the transceiver coil alone. Increases in SNR and g-factor performance are expected to improve clinically oriented UHF shoulder MRI at 7T.
08:27		1175. The Equitable Coil: A Size-Adaptable 104-Channel Receive RF Coil for Human Head Imaging at 3T Using a Flexible Plate Approach View Presentation Video W. Mathieu, J. Campos Pazmiño, E. McNabb, I. Levesque, M. Popović, R. Farivar McGill University, Montreal, Canada Impact: We present the concept of equitable imaging with a size-adaptable, flexible 104-channel receive-only RF coil which improves cortical SNR across head shapes. Elements are placed in sub-arrays on semi-flexible plates allowing them to be placed close to any head.
08:39		1176. An Open-face 8-Channel Transceive 32-Channel Receive Array for Human Visual Cortex Imaging at 7T View Presentation Video S. Chu, D. Baskaran, B. Ding, S. Allwood Spiers, Y. Lazarova, L. Petro, L. Muckli, S. Gunamony University of Glasgow, Glasgow, United Kingdom Impact: The high gain in SNR will enable high-spatial resolution BOLD signal in the occipital cortex while simultaneously stimulating a large visual field extending far into the periphery, to perform layer-specific fMRI around the blind spot and peripheral visual fields.
08:51		1177. Integrated 48-channel B0 shim, 6-Dipole transceive, and 16-loop receive system for high-quality NHP brain imaging at 7T View Presentation Video E. Djaballah, A. Uthayakumar, M. Roustan, M. Gay, E. Giacomini, P-F Gapais, M. Luong, A. Amadon, Q. Zhu Cognitive Neuroimaging Unit, INSERM, CEA, Université Paris -Saclay, NeuroSpin Center, GIF-SUR-YVETTE, France, GIF-SUR-YVETTE, France Impact: Our combined MCA B₀ shim and RF antenna system improves B₀ homogeneity and SNR, enabling clearer, artifact-reduced whole-brain imaging of NHPs at 7T. This setup opens new avenues for studying complex neural responses and fine-grained structures in NHPs.
09:03		1178. An Optimized RF Coil Design for in vivo Non-Human Primate Subjects at 10.5 Tesla View Presentation Video M. Waks, A. Bratch, S. Jungst, R. Lagore, A. Sadeghi-Tarakameh, K. Ugurbil, J. Zimmermann, G. Adriany University of Minnesota, Minneapolis, United States Impact: Developing a translational brain model using non-human primates is essential to establishing functional relationships applicable to the human brain. Recent hardware and software developments in Ultra-High Field MRI can facilitate growth of non-human primate applications, leading to improved brain mapping.
09:15		1179. The RF Cap: a 26-channel flexible RF-coil cap for optimized concurrent TMS/fMRI and TMS/EEG/FMRI acquisition at 3T. View Presentation Video L. Navarro de Lara, S. Ardila, J. Stockmann, L. Craven-Brightman, M. Daneshzand, Y. Ma, L. Wald, J. Ahveninen, A. Nummenmaa A. A. Martinos Center for Biomedical Imaging/MGB, Charlestown, United States Impact: To enable concurrent MRI and neuromodulation we present a first-of-its-kind wearable RF cap that will allow full brain concurrent TMS/fMRI and TMS/EEG/fMRI acquisitions with high sensitivity and using high acceleration factors.
09:27		1180. A 16 Channel TxRx Coaxial-End Dipole Array for Combined Head and C-spine MRI at 9.4T View Presentation Video G. Solomakha, F. Glang, M. May, J. Walzog, D. Bosch, O. Kraff, K. Scheffler, H. Quick, N. Avdievich Max Planck Institute for Biological Cybernetics, Tübingen, Germany Impact: We developed a 16-channel array for combined head and C-spine MRI at 9.4T. The array could be used for MR studies of this region at 9.4T. The proposed design could also be adapted to 7T or 10.5T.
09:39		1181. Towards time-efficient sodium and proton MRI at 7T View Presentation Video M. Wu, J. Cleary, P. Bridgen, P. Di Cio, S. McElroy, S. Rot, Y. Blunck, D. Carmichael, Ö. Ipek King's College London, London, United Kingdom Impact: Pilot results demonstrate that integrated multichannel ²³Na/¹H transmit-receive RF coil design at 7T enables sufficient image quality without patient repositioning, streamlining workflow and reducing co-registration demands, paving the way for time-efficient multinuclear imaging in clinical applications.
09:51		1182. Radiation-Free Dental Imaging: High-Resolution MRI with a Wireless Braces-Shaped Coil——Try to beat CBCT View Presentation Video E. Xiao, S. Hayat, W. Liao, P. He, N. Li, F. Du, X. Zhang, Q. Chen, Y. Li Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, Shenzhen, China Impact: This intraoral braces-shaped wireless coil offers a radiation-free alternative to CBCT with high-resolution dental imaging and improved soft tissue contrast.
10:03		1183. A Universally Sized, High-Resolution and Parallel Imaging Optimized 32-Channel Ultra-flexible Phased-Array for 3T Small Joint MRI View Presentation Video Y-J Stickle, C. Follante, C. Aspy, S. Blankenship, T-Y Yang, K. Barnhart, K. Calderwood, T. Stickle, F. Robb, M. Fung, Y. Wen, E. T. Tan, A. Lowe, D. B. Sneag GE Healthcare, Aurora, United States Impact: An optimized small loop coil design, with flexible mechanics, provides improved z-coverage, comfortable fit, high-resolution and higher acceleration for in-vivo 3T hand/wrist MRI.
