Make MRI coils great again

ABOUT US

The MR Engineering Lab is part of the Brain Imaging and Analysis Center at Duke University. Our research involves the development of innovative MRI technologies, such as integrated parallel reception, excitation, and shimming (iPRES) coil arrays and integrated RF/wireless coil arrays, to improve the image quality and clinical utility of various MRI applications in the human brain and body, such as functional MRI and diffusion-weighted imaging.

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.
