Recent RSL Research
-
Accelerated Imaging of Metallic Implants Using Model-Based Nonlinear Reconstruction
Total joint replacement is a common surgery to treat end-stage joint pain, which is projected to exceed 4.
-
Motion-Robust Reconstruction of Multishot Diffusion-Weighted Images without Phase Estimation
Diffusion-weighted MRI is a widely used technique in neuroscience research, as well as for many clinical applications.
-
Diffusion MRI Tractography for Improved Transcranial MRI-guided Focused Ultrasound Thalamotomy Targeting for Essential Tremor
Our study supports the use of diffusion tractography as a complementary approach to improve the current targeting methods for tcMRgFUS thalamotomy.
-
SNR-Weighted Regularization of ADC Estimates from Double‐Echo in Steady‐State (DESS)
Osteoarthritis is a difficult condition that has painful and debilitating effects on many people, leading to high medical costs.
-
Characterizing Signals Within Lesions and Mapping Brain Network Connectivity After Traumatic Axonal Injury: A 7 Tesla Resting-State FMRI Study
In this study, we characterize RS-FMRI signal time course properties and evaluate different seed placements within and around hemorrhagic traumatic axonal injury (hTAI) lesions. RS-FMRI was performed on a 7 Tesla scanner in a patient who recovered consciousness after traumatic coma and in three healthy controls.

New publication: Measurements of the Relationship Between CT Hounsfield Units and Acoustic Velocity and How It Changes With Photon Energy and Reconstruction Method
While several studies have investigated the relationship between acoustic velocity and CT Hounsfield units (HUs), these studies have largely ignored the impact of X-ray energy, reconstruction method, and reconstruction kernel on the measured HU, and therefore the estimated velocity, and none have measured the relationship directly.

Quantitative Imaging of Bone-Cartilage Interactions in ACL-Injured Patients with PET-MRI
Osteoarthritis (OA) is a degenerative whole-joint disease that affects more than half of the population during their lives and is the leading cause of disability worldwide.
-
MR Imaging of Magnetic Ink Patterns via Off-Resonance Sensitivity
The magnetic susceptibility effects of magnetic ink in MRI can be exploited to visualize magnetic ink patterns placed on the skin.
-
Super-Resolution Musculoskeletal MRI Using Deep Learning
In this manuscript, we have demonstrated a method termed ‘DeepResolve’, which can transform low-resolution magnetic resonance images (MRI) into higher-resolution images.
-
Artifact-Reduced Imaging of Biopsy Needles with 2D Multispectral Imaging
We have validated the use of an MR imaging method that reduces the image artifacts due to metal objects for tracking biopsy needles in MR-guided procedures.
