		Computer Number: 113 3296. Cardiac MR Gating Using a Non-contact MR-compatible Doppler Radar System at 3T: Initial Results on Healthy Subjects View Presentation Video T. Wu, H. Hong, M. Qin, Z. Cai, S. Han, Y. Li, X. Xia, L. Hu, P. Hu, Z. Ren ShanghaiTech University, Shanghai, China Impact: The proposed cardiac radar provides a non-contact alternative for cardiac gating in MRI. Future research may explore signal biological mechanisms and its additional applications in respiratory gating.
		Computer Number: 114 3297. Quadric Conformal Metamaterials with Torus-Knotted Coils and Kerf-Structured Panels for Magnetic Resonance Imaging View Presentation Video B. Li, E. Zhou, Z. Mei, R. Xie, C. Liang, Z. You, H. Guo, X. Zhao Tsinghua University, Beijing, China Impact: The proposed metamaterial achieves 9-fold SNR enhancement and is suitable for applications in joint and head MRI. These findings suggest possibilities for wearable metamaterials adaptable to various human body surfaces by incorporating further stiffness control.
		Computer Number: 115 3298. Compact, Elliptical-Toroid Floating Cable Traps View Presentation Video J. Vincent, V. Taracila, D. Anderson, R. Stormont, F. Robb GE HealthCare, Aurora, United States Impact: Our design demonstrates the possibility of lighter-weight cable traps that reduce heating and field distortion, minimize coupling with the coil and adjacent cable traps, and could improve safety through further minimizing the risk of RF burns on patients.
		Computer Number: 116 3299. Simple Universal Codes: Lossless Compression for Lower MRI Data Transmission Rates View Presentation Video T. Zhang, F. Robb, S. Vasanawala, J. Pauly, G. Scott Stanford University, Stanford, United States Impact: MRI k-space data appears compressible by 3x before data transmission. This means band-limited wireless coil arrays (WiFi or ultra-wideband) could support image 3x higher throughput, or operate with significantly slower link rates. This would be crucial for robust performance.
		Computer Number: 117 3300. Techniques in Low-IF, Low Power MRI Front Ends View Presentation Video A. Fontaine, F. Robb, S. Vasanawala, J. Pauly, G. Scott Stanford University, Stanford, United States Impact: If the front end electronics can be distributed on the coil array, this opens the possibility of data transmission with a wireless interface. The receive topology could eliminate cable trap baluns, which inhibit flexibility and wearability, compromising form factor.
		Computer Number: 118 3301. Imaging Heart Motion Using Differential Scattering Parameters: An AI-Based Approach View Presentation Video E. F. Meliado, V. Koloskov, C. A. van den Berg, B. R. Steensma University Medical Center Utrecht, Utrecht, Netherlands Impact: RF-based imaging offers the potential for patient friendly and accessible cardiac imaging, with potential applications in continuous cardiovascular health monitoring, including heart failure management.
		Computer Number: 119 3302. Splittable wireless resonator array for intraoperative MRI View Presentation Video H. Zhu, C. Zhou, M. Lu, R. Wang, R. Li, Y. Chen, X. Yan Sino Canada Health Institute Inc., Winnipeg, Canada Impact: This design improves iMRI and MR-guided therapy applications by providing a cost-effective, easy-to-use solution that supports advanced imaging capabilities and surgical requirements.
		Computer Number: 120 3303. AirLink Multi-Resonator Array View Presentation Video H. Zhu, F. Wang, Q. Zhang, Y. Chen, R. Li, X. Yan Sino Canada Health Institute Inc., Winnipeg, Manitoba, Canada, Winnipeg, Canada Impact: The approach of combining wireless resonators with a conventional array significantly simplifies MRI coil design, improves image SNR, reduces costs, and ensures compatibility for parallel imaging across all major platforms and field strengths.
		Computer Number: 121 3304. Wireless Integrated Sensing Detector for simultaneous EEG and MRI (WISDEM) C. Qian, Y. Chen, X. Yu Michigan State University, East Lansing, United States Impact: This 2-in-1 transducer will enable cross-scale brain mapping.
		Computer Number: 122 3305. ULTRA2: a novel system for multi-focal, low-intensity focused ultrasound neuromodulation and whole-brain, ultra-high field MRI at 7T View Presentation Video D. Wenz, L. Tiston, J. Philippe, K. Pierzchala, R. Salomir CIBM Center for Biomedical Imaging, Lausanne, Switzerland Impact: ULTRA² will enable multi-focal, high-precision LIFU neuromodulation guided using advanced UHF neuroimaging strategies, thereby adding a new dimension to developing non-invasive treatment strategies for neurological and neuropsychiatric diseases.
		Computer Number: 123 3306. Three-Channel Modular Transmit Array for RF Gradient MRI: Enabling Low-Cost, Scalable RF Arrays Through Active Decoupling View Presentation Video N. Bolding, C. Vaughn, A. Patel, S. Lin, J. Sun, W. Grissom, M. Griswold Case Western Reserve University, Cleveland, United States Impact: Enabling high RF transmit channel count is essential for RF encoded imaging techniques like Selective Excitation through Nutation and Fingerprinting (SENF). Novel transmit system architecture presented here enables a reduction in system cost and easier array scaling while increasing portability.
		Computer Number: 124 3307. An Add-on System for Enabling Simultaneous/Interleaved Multinuclear MRI/MRS Experiments View Presentation Video J. Hou, C. Bauer, M. McDougall, S. Wright Texas A&M University, College Station, United States Impact: We propose a cost-effective, phase-stable solution to enable a traditional scanner with simultaneous/interleaved multinuclear capability. This approach eliminates the need for retrospective phase correction, enabling the user to directly view/process the acquired multinuclear data on the console.
		Computer Number: 125 3308. Implementation and characterization of MIMO RF navigators towards robust TR-by-TR head motion sensing View Presentation Video P. Krahn, S. Anand, M. Lustig University of California, Berkeley, Berkeley, United States Impact: We present and characterize the first system for multiple-input multiple-output (MIMO) RF motion sensing with BPT and PT, aimed toward head motion sensing and correction at arbitrary frequencies, and simultaneous to the MRI exam.

Navarro de Lara, M. Daneshzand, S. Huang, A. Nummenmaa, J. Stockmann Martinos Center for Biomedical Imaging, Charlestown, United States Impact: TMS coils can be utilized to reduce the field of view by exciting the part of the brain targeted only. This may offer improved capabilities for mapping of the TMS-induced brain activation more accurately.
		Computer Number: 127 3310. Towards Accurate and Automated TMS Coil Placement with a Robotic System in MRI: A preliminary study View Presentation Video A. De Goyeneche, N. Zhao, C. Paxson, B. He, R.

		Computer Number: 128 3311. Metamaterial-aided reconstruction of under-sampled k-spaces View Presentation Video I. Lee, D. Hoinkiss, J. Huber, D. Philipp, J. Müller, M. Günther University of Bremen, Bremen, Germany Impact: Reducing acquisition time improves patient comfort and reduces motion artifacts. To achieve further acceleration, however, the frequency encoding should be under-sampled. While the method presented in this abstract can theoretically accomplish this, new configurations of metamaterials must be investigated.
