This technology includes a microscopy technique that combines the strengths of multiview imaging (better resolution isotropy, better depth penetration) with resolution-improving structured illumination microscopy (SIM). The proposed microscope uses a sharp line-focused illumination structure to excite and confocally detect sample fluorescence from 3 complementary views.
This technology includes a method that extends fluorescence polarization imaging so that the dipole moment of a fluorescent dye may be excited regardless of its 3D orientation. By exciting the dipole from multiple directions, we ensure that excitation may occur even if the dipole is unfavorably oriented along the axial (propagation) axis. If the dye can be rigidly attached to the structure of interest, our method also enables the 3D orientation of the structure to be estimated accurately.
This technology includes improvements in the fluorescence scanner to increase efficiency. This method works by eliminating the need to radially slide the optical assembly during scanning, instead using a galvanometric mirror deflecting a laser beam to different positions in the sample. This allows the scanner to be incorporated into existing commercial analytical ultracentrifugation (AUC) systems with minimal modifications.
This technology includes a microscopy technique that produces super-resolution images from diffraction-limited images obtained from a line scanning confocal microscope. First, the operation of the confocal microscope is modified so that images with sparse line excitation are recorded. Second, these images are processed to increase resolution in one dimension. Third, by taking a series of such super-resolved images from a given sample type, a neural network may be trained to produce images with 1D super-resolution from new diffraction-limited images.
This technology includes a blood flow imaging method that allows for a higher density of smaller particles to be detected. Current imaging methods that are based on Doppler measurements are limited by the discontinuity in the capillary flow in the space between red blood cells. The core technology is to use a scattering agent to enhance capillary flow or microcirculation. This technology has been tested for optical coherence Doppler tomography, but can be expended to any Doppler based flow imaging techniques such as laser speckle imaging.
Taxus® Express2™ has the potential to benefit many of the victims of cardiovascular disease, which causes 40% of all deaths in the US. After a heart attack, patients often undergo an invasive by-pass surgery or a less invasive angioplasty procedure to open up the clogged artery. In the latter procedure, a tiny meshlike device called a stent is inserted into the artery to keep it propped open. However, in many of the stent placement cases, the body reacts to this foreign object with scar tissue formation and the artery narrows again.
The transferred technology is a non-invasive, intensive, swallowing retraining device that combines sensory stimulation with motor retraining to rehabilitate swallow function, initially targeted for dysphagia patients. Dysphagia is a common disorder that creates difficulty swallowing. Patients at risk of choking on fluid or food face a risk of life-threatening aspiration pneumonia and may need to be fed through a tube.
