Non-Invasive Cell Size Detection

Vanderbilt researchers have developed a new method for using contrast enhanced MRI to non-invasively map and quantify cell size on a voxel-by-voxel basis. Using this approach, it is possible to monitor and detect diseases or treatments that alter the distribution of cell sizes such as cancer, muscular dystrophy, hepatocellular hypertrophy, and hypertrophic cardiomyopathy.

Latent Image-Derived Features for Prognostic Modeling

Researchers at Vanderbilt have developed a system to estimate prognostic metrics such as the length of a hospital stay, recovery status at discharge, and overall health at discharge, using only baseline imaging and clinical information gathered early in the hospital admission process. This system can assist with medical group operations and planning, it can help to educate families and patients regarding prognosis, and can be used to automatically stage patients for clinical trials.

A Simple and Highly Portable Flow Phantom for Doppler Ultrasound Quality Measurements

A new phantom has been designed in which Doppler ultrasound measurements can be conducted for quality assurance purposes. The phantom is highly portable, does not require power to operate, and allows for simple and reproducible measurements of Doppler ultrasound function. This combination of advantages allows for realistic monthly, weekly, even daily Doppler QA measurements.

Real-time Detection of Position and Orientation of Wireless Endoscopy Capsule using Magnetic coupling

Vanderbilt researchers have developed a new system to detect the position, orientation, and pressure exerted on surrounding tissues of a wireless capsule endoscopy device.  Magnetic coupling is one of the few physical phenomena capable of transmitting actuation forces across a physical barrier.  Magnetic manipulation has the potential to make surgery less invasive, by allowing untethered miniature devices to enter the body through natural orifices or tiny incisions, and then maneuver with minimal disruption to healthy tissue.  In order to accomplish this goal, the pose (position and orientation) of the medical device must be available in real time.

Non-Invasive Skin Cancer Detection using Raman Spectroscopy-OCT System (Portfolio)

Vanderbilt University researchers have designed a system for non-invasive discrimination between normal and cancerous skin lesions. The system combines the depth-resolving capabilities of OCT technique with Raman Spectroscopy's specificity of molecular chemistry. By linking both imagining techniques into a single detector arm, the complexity, cost, and size of previously reported RS-OCT instruments have been significantly improved. The combined instrument is capable of acquiring data sets that allow for more thorough assessment of a sample than existing optical techniques.

Systems and Methods for Optical Stimulation of Neural Tissues (Portfolio)

Vanderbilt researchers have developed a novel technique for contactless simulation of the central nervous system.  This involves the use of infrared neural stimulation (INS) to evoke the observable action potentials from neurons of the central nervous system.  While infrared neural stimulation of the peripheral nervous system was accomplished almost a decade ago, this is the first technique for infrared stimulation of the central nervous system. This technology has been protected by a portfolio of issued patents.

Miniature Optical Coherence Tomography Probe for Real-time Monitoring of Surgery

Vanderbilt researchers have designed a forward scanning miniature intraoperative Optical Coherence Tomography (OCT) probe that can be used for diagnostic purposes and real-time monitoring of surgery within small spaces, such as endoscopic surgery, intraocular surgery, and other microsurgery.

Two Degrees-of-Freedom, Fluid Power Stepper Actuator Model

Vanderbilt researchers have developed a novel technology for use of a flexible fluidic actuator in MRI-guided surgical systems. This method eliminates the need for moving the patient out of the MRI machine, onto an operating table, and back in order to perform procedures. It is a safe, sterilized, and successful method to simplify MRI-guided surgical procedures.

Heterogeneous catalysis of NMR Signal Amplification by Reversible Exchange(SABRE)

Vanderbilt researchers have developed heterogeneous catalysis and catalyst for the NMR Signal Amplification by Reversible Exchange (SABRE) hyperpolarization process. Coupled with the researchers' development of a method to perform SABRE in aqueous solutions, this discovery could allow fully biocompatible SABRE hyperpolarization processes in water with catalyst recycling. This would allow the production of pure aqueous contrast agents requiring only parahydrogen as a consumable.

NMR Signal Amplification by Reversible Exchange (SABRE) in Water

Vanderbilt researchers have developed a method to perform the Parahydrogen Induced Polarization (PHIP) based method of Signal Amplification by Reversible Exchange (SABRE) in aqueous media. This allows the resulting hyperpolarized molecules to be used for in vivo applications.
