What we work on
Engineering solutions for MRI's hardest technical problems
Better RF and B0 homogeneity, less RF heating near implants, fewer motion artifacts, faster acquisition and higher SNR.
RF coils & arrays
Self-decoupled, flexible and wireless RF coils that raise SNR and simplify array design for clinical and preclinical MRI.
B0 shimming hardware
RF-transparent B0 shim coil arrays and integrated RF/shim coils that correct field inhomogeneity where it matters most.
RF & B1 homogeneity
Passive and parallel-transmit solutions for dark bands and B1 non-uniformity at 3T and 7T.
Implant safety
Novel materials and devices that reduce RF heating near implants, expanding safe access to MRI.
MRI-guided therapy
Hardware for MR-guided focused ultrasound (tcMRgFUS), including passive antennas that remove dark-band artifacts.
Portable & low-cost MRI
Low-cost wireless coils and portable MRI hardware that bring imaging to more patients and sites.
