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.

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.

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.

PIQASO: A rigid phantom for comprehensive end-to-end evaluation of online adaptive radiotherapy systems

There is currently no radiotherapy phantom capable of quantitatively assessing all components of an online adaptive radiotherapy (online ART) system in a comprehensive end-to-end test.Represented here is a novel, rigid phantom that can simultaneously evaluate an online ART system's image acquisition, deformable image registration, contour propagation, plan re-optimization, dose calculation, and beam delivery in a single process that is robust, quantitative, and convenient.

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.

A Method to Obtain Uniform Radio Frequency Fields in the Body for High Field MRI

Researchers at Vanderbilt have created a new approach to produce uniform radio frequency (RF) fields in the body during high field magnetic resonance imaging (MRI). Existing high field MRI machines create non-uniform RF fields that lead to non-uniform sensitivity in the generated images, also referred to as "hot" and "cold" spots. These local variations interfere with the tissue contrast of the images that radiologists depend upon to make accurate diagnoses. By generating uniform RF fields in the body, this technology provides the benefits of high field MRI without the non-uniform RF fields.

Enhanced Optical Imaging for the Treatment of Retinal Disease

Vanderbilt researchers have developed a system for enhancing the imaging capabilities of optical coherence tomography (OCT), a tool commonly used to monitor and treat patients with retinal disease. The image resolution of OCT, however, is intrinsically limited. Ideally, a contrast agent could be used to highlight specific parts of the retina within the image, but dye alone is largely ineffective because of the way OCT generates the image. Photothermal heating solves this problem by creating local zones of tissue expansion which can be distinctly detected by OCT. Photothermal-OCT is safe, effective, and enhances the imaging power of a tool widely used by opticians.

Systems and Methods for Non-destructive Evaluation of Optical Material Properties and Surfaces

A team of Vanderbilt researchers has developed a novel system and method for non-destructive characterization of compound lenses. The approach uses optical coherence tomography and reflectance confocal microscopy to fully characterize lens geometry and glass materials, enabling accurate modeling of compound lenses.
