Make MRI coils great again
ABOUT US
RESEARCH
iPRES
We developed a novel integrated parallel reception, excitation, and shimming (iPRES) coil design that allows RF and DC currents to flow on the same coil, enabling MR imaging and localized B0 shimming with a single coil array (Han et al. 2013).
iPRES | brain
We implemented the iPRES technology into a 32-channel head coil array and showed that it can substantially reduce localized B0 inhomogeneities and image distortions in brain imaging (Truong et al. 2014).
iPRES-B | brain
We developed a plug-and-play, battery-powered iPRES (iPRES-B) head coil array to enable a wider adoption of this technology in clinical applications (Darnell et al. 2017).
iPRES | fMRI
We developed a novel iPRES shim optimization method that can not only correct for image distortions, but also recover signal loss, in functional MRI applications (Willey et al. 2018).
iPRES(N) | body
We developed a novel iPRES(N) coil design with N DC loops per RF coil element, implemented it into an 8-channel body coil array, and showed that it can shim localized B0 inhomogeneities in abdominal imaging more effectively than the iPRES coil design (Darnell et al. 2017).
iPRES(N)-A | body
We developed a novel adaptive iPRES(N) (iPRES(N)-A) coil design using microelectromechanical system switches and showed that it can achieve a similar shimming performance as that of the iPRES(N) coil design, while reducing the number of power supplies by a factor N (Darnell et al. 2018).
iPRES | breast
We implemented the iPRES coil design into an 8-channel breast coil array and showed that it can substantially reduce localized B0 inhomogeneities and image distortions in breast imaging (Ma et al. 2018).
RF/wireless & iPRES-W
We developed novel integrated RF/wireless and wireless iPRES (iPRES-W) coil designs that allow RF currents, at the Larmor frequency and in a wireless communication band, and a DC current to flow on the same coil, enabling MR imaging, wireless communication, and localized B0 shimming with a single coil (Darnell et al. 2019).
iPRES-W | spinal cord
We integrated the iPRES-W coil design with the novel AIR coil technology and showed that it can wirelessly shim localized B0 inhomogeneities and reduce image distortions in spinal cord imaging (Cuthbertson et al. 2019).
integrated RF/wireless
We performed finite element simulations to optimize the far-field gain, directivity, and link budget of an integrated RF/wireless coil within the scanner bore (Bresticker et al. 2019).
intracortical DTI
We are investigating the feasibility of using high-resolution intracortical diffusion tensor imaging for the early detection of neurodegeneration in Alzheimer’s disease.
