In vivo optical biopsy applicator of the vaginal wall for treatment planning, monitoring, and imaging guided therapy

Pelvic floor disorders (PFDs) afflict nearly 25% of all women and carry a host of symptoms that can drastically reduce quality of life. Despite their prevalence, the complex and varied nature of such PFDs make them difficult to diagnose and treat. Researchers at UCI have developed an entirely integrated system that, for the first time, provides real-time monitoring of the vaginal wall tissue during diagnosis and treatment, allowing for more thorough diagnoses and more effective treatment methods.

Endoscopic Optical Coherence Tomography As A Minimally Invasive Lung Cancer Screening Tool To Guide Diagnosis And Therapy

Method for Early Detection of Edema and Intercranial Pressure

Researchers at UCR have developed a process that uses optical coherence tomography (OCT) on specific regions of the cranium to detect the onset of edema before severe damage can be done to the brain.  By scanning various regions of the brain with OCT, the early stages of cerebral edema may be visualized at a far earlier time point than otherwise possible.  The scattering pattern of reflected light changes in a predictable manner when brain water content increases.  This allows for a quick and accurate determination of a patient’s risk for developing dangerous ICP levels, thus eliminating the need for a invasive precautionary craniectomy.

High Frequency Digital Frequency Domain Fluorescence Lifetime Imaging System For Applications On Tissues

The technology is a software/hardware combination designed to enhance sampling rate for frequency domain fluorescence lifetime imaging. Fluorescence lifetime imaging microscopy (FLIM) is a technique that uses signals emitted from fluorescent samples to construct images of those samples in near real time. An advantage to FLIM is its ability to image large fields of view, which makes it an attractive option for dynamical measurements of live biological tissues. The higher sampling rate available using this technology will allow for more information to be gleaned from biological samples, which may have a fluorescence band up to 1 GHz, advancing tissue imaging.
