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.
Vanderbilt researchers have developed a technology for suppressing end-face reflections in most fiber optic components, thereby reducing a significant source of noise in fiber-optic systems. The solution employs a fused-spliced length of angle-polished no-core fiber in order to angle reflections outside the acceptance numerical aperture of the fiber and spatially offsetting any reflections to minimize back-coupling. The result is a compact solution that significant decreases noise without significantly altering the specifications of the fiber-optic component.
A team of Vanderbilt researchers has developed a novel fiducial marker for use during radiosurgery of the eye. The fiducial is a non-invasive, comfortable method for performing registration of preoperative medical images and the radiotherapy target during therapy. The device aims to remove the need for existing invasive registration procedures, while still providing accurate localization to the clinician.
Vanderbilt researchers have discovered a method ofmonitoring the placement of electrodes in cochlearimplants (CIs) through the use of electrical impedancemeasurements. This technology offers real-timefeedback on electrode positioning, which can beused to more accurately place electrodes duringinitial implantation, or better program the implantsafter they have been placed. These enhancementscombine to give increased hearing quality to bothnew and existing CI patients.
An assistive device for individuals with upper extremity neuromuscular deficit has been developed by researchers at Vanderbilt. This device is specifically designed for patients having hemiplegia following stroke, incomplete spinal cord injury, multiple sclerosis, and other disabilities and conditions, who may have severe muscle weakness or inability to fully control an upper limb. In order to facilitate use of the upper limb, the patient can wear the device as a substitute for or a supplement to the patient's volitional movement.
Vanderbilt researchers have developed a wearable surgical camera designed for use over the top of a surgical gown. The system, nicknamed Cleopatra, is designed specifically for the OR, maintains a consistent view of the operative field during a procedure, and is capable of supporting video, audio, lighting, and other technology in the immediate vicinity of the surgical field.
A new approach for obtaining less invasive optical measurements of the cervix has been developed that does not require the use of a speculum exam. This technology can visualize the cervix in vivo to find unique biomarkers that indicate various conditions such as preterm labor, cancer, human papillomavirus (HPV), and dysplasia.
Vanderbilt University researchers have developed self-destructing electrical conductors that dissolve and vanish below a certain critical temperature, which is achieved either by actively cooling the circuit or by removing a heat source.
A Vanderbilt University research team led by Professor John Wikswo has developed low-cost, small-volume, metering peristaltic micropumps and microvalves. These pumps and valves can be used either as stand-alone devices incorporated into microfluidic subsystems, or as readily customized components for research or miniaturized point-of-care instruments, Lab-on-a-Chip devices, and disposable fluid delivery cartridges.
