Selective Size Imaging using Filters via Diffusion Times (SSIFT)

Vanderbilt researchers have developed a novel MRI-based method for fast, robust, and accurate imaging of biological tissue by selecting a specific cell size range (such as tumors) without the need for a contrast agent. One exciting application of this method is imaging brain metastases (BM) that are difficult to differentiate from other brain abnormalities such as radionecrosis when using existing approaches.

Self-Decoupled RF Coils for Optimized Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is one of the most important and versatile tools in the repertoire of diagnostics and medical imaging. Vanderbilt researchers have developed a novel, geometry independent, self-decoupling radiofrequency (RF) coil design that will allow MRI machines to generate images at a faster rate and with greater image quality.

Easy to Use Patient Immobilizer for Stabilizing Limbs During MRI Imaging

Vanderbilt students have created a stabilization system for secure and stable MRI positioning of hands, wrists, knees, shoulders, and the lower back, using affordable, easy to use, and readily available materials. The system effectively reduces image blurring using a non-irritating film and a supportive frame. This device can simultaneously improve MRI diagnosis, enhance the patient experience, and minimize the time and financial burdens of image retakes.

Model-based Compression Correction Framework for Ultrasound

Vanderbilt researchers have developed a system that corrects for compressional effects in ultrasound data during soft tissue imaging. The system uses tracking and digitization information to detect the pose of the ultrasound probe during imaging, and then couples this information with a biomechanical model of the tissue to correct compressional effects during intraoperative imaging.

Trackerless Image-Guidance Using a Surgical Microscope

Researchers at Vanderbilt have developed a new image-guided, trackerless surgical microscope system to be used in soft tissue surgeries. The current method is to use a surgical microscope along with an image-guided system. This new design eliminates the need for a separate image-guidance system; the entire guidance environment can be realized within the microscope environment.

Image Guidance System for Breast Cancer Surgery

Vanderbilt researchers have developed an image guidance system that aims to reduce the revision rate for breast conserving surgeries through the use of intraoperative tumor location. The platform integrates MRI imaging, optical tracking, tracked ultrasound, and patient specific biomechanical models to provide a superior tumor localization end result.

Modeling Tissue Elasticity as a Complement to Imaging Modalities

A Vanderbilt researcher has developed an elastography framework for determining elastic properties of tissue using existing imaging technologies. Elastography is the direct imaging of tissue elasticity parameters, and can be quite helpful for diagnostic and/or therapeutic purposes.

Laser Range Scanning for Cortical Surface Registration & Deformation Tracking

This technology is fundamentally a new way to align a patient in an image-guided surgery system (registration) without the use of fiducial markers on the cranium exterior. The system utilizes laser range scanning technology, the natural features on the cortical surface, and the corresponding natural features derived from the patient's preoperative magnetic resonance tomograms. In addition, the technology is amenable to measuring deformation (brain shift) for use within a mathematical model-based strategy for shift compensation.

Inexpensive Disposable Hydro-Jet Capsule Robot for Gastric Cancer Screening in Low-Income Countries

Gastric cancer is the second leading cause of cancer death worldwide. While screening programs have had a tremendous impact on reducing mortality, the majority of cases occur in low and middle-income countries (LMIC). Typically, screening for gastric and esophageal cancer is performed using a flexible endoscope; however, endoscopy resources for these settings are traditionally limited. With the development of an inexpensive, disposable system by Vanderbilt researchers, gastroscopy and colonoscopy can be facilitated in areas hampered by a lack of access to the appropriate means.

Non-Invasive Bacterial Identification for Acute Otitis Media using Raman Spectroscopy

Vanderbilt researchers have developed an optical-based method for real-time characterization of middle ear fluid in order to diagnose acute otitis media, also knows as a middle ear infection. The present technique allows for quick detection and identification of bacteria and can also be applied to other biological fluids in vivo.
