ABOUT US

The MR Engineering Lab is part of the Brain Imaging and Analysis Center at Duke University. Our research involves the development of novel magnetic resonance imaging (MRI) coil technologies – specifically, integrated parallel reception, excitation, and shimming (iPRES) and integrated radio-frequency/wireless (iRFW) coils – to enable imaging, localized B0 shimming, and/or wireless communication with a single coil, thereby improving the image quality and clinical utility of MRI applications such as functional MRI (fMRI) and diffusion-weighted imaging (DWI) in the human brain and body. We also develop high-resolution diffusion tensor imaging (DTI) techniques to investigate the microstructure of the human brain and to detect abnormalities in neurological disorders such as Alzheimer’s disease.

iPRES COIL TECHNOLOGIES

iPRES

We developed a novel iPRES coil design that allows RF and DC currents to flow on the same coil elements, enabling MR imaging and localized B0 shimming with a single coil array (Han et al. 2013).

iPRES | brain

We implemented iPRES into a 32-channel head coil array to effectively reduce localized B0 inhomogeneities and image distortions in the brain (Truong et al. 2014).

iPRES(N) | body

We implemented a novel iPRES(N) coil design, with N DC loops per RF coil element, into an 8-channel body coil array to more effectively shim localized B0 inhomogeneities in the abdomen (Darnell et al. 2017).

iPRES-B | brain

We developed a plug-and-play battery-powered iPRES head coil array to enable a more efficient and cost-effective shimming in clinical applications (Darnell et al. 2017).

iPRES(N)-A

We developed a novel adaptive iPRES(N) (iPRES(N)-A) coil design that uses switches to achieve a more cost-effective localized B0 shimming (Darnell et al. 2018).

iPRES | fMRI

We developed a novel iPRES shim optimization method to effectively reduce both image distortions and signal loss for fMRI applications (Willey et al. 2021).

iPRES | breast

We implemented iPRES into an 8-channel breast coil array to enable localized B0 shimming in DWI of the breast (Ma et al. 2018).

iPRES(N)-A | body

We implemented iPRES(N)-A into a 32-channel body coil array to enable localized B0 shimming in DWI of the abdomen (Ma et al. 2020).

iPRES | rat

We numerically optimized an iPRES rat coil design to achieve a high localized B0 shimming performance and signal-to-noise ratio (Thompson et al. 2020).

iRFW COIL TECHNOLOGIES

iRFW & iPRES-W

We developed novel iRFW and wireless iPRES (iPRES-W) coil designs that enable MR imaging, wireless communication, and/or localized B0 shimming with a single coil (Darnell et al. 2019).

iPRES-W | spinal cord

We implemented iPRES-W, along with the AIR™ coil technology, into a 4-channel spine coil array to enable wireless localized B0 shimming in DTI of the spinal cord (Cuthbertson et al. 2022).

iRFW

We performed simulations to optimize the wireless performance of iRFW coils (Bresticker et al. 2019).

iRFW | ultrasound

We integrated the iRFW coil design with an ultrasound-based sensor to enable MR imaging and wireless physiological motion monitoring (Willey et al. 2020).

dual-stream iPRES-W | brain

We implemented a dual-stream iPRES-W coil design into a 48-channel head coil array to enable MR imaging, wireless localized B0 shimming, and wireless respiratory monitoring (Cuthbertson et al. 2020).

iRFW | Q-spoiling

We developed an iRFW coil design that can perform wireless Q-spoiling to detune the coil during each RF transmit cycle (Cuthbertson et al. 2021).

power harvesting

We developed a power harvesting coil array that can harvest the energy from the RF transmit pulses to power electronics within the scanner bore (Cuthbertson et al. 2022).

HIGH-RESOLUTION DTI

DTI | cortical gray matter

We developed a cortical column-based analysis of submillimeter whole-brain DTI data to quantify the dependence of the diffusion anisotropy and radiality on the cortical depth, curvature, and region-of-interest (Ma et al. 2021).

DTI | hippocampus

We analyzed submillimeter DTI data of the hippocampus to investigate intra-hippocampal fiber tracts and connectomes in vivo and ex vivo (Ma et al. 2022).
