Preferred embodiments of the present invention are directed to systems for phase measurement which address the problem of phase noise using combinations of a number of strategies including, but not limited to, common-path interferometry, phase referencing, active stabilization and differential measurement. Embodiment are directed to optical devices for imaging small biological objects with light. These embodiments can be applied to the fields of, for example, cellular physiology and neuroscience. These preferred embodiments are based on principles of phase measurements and imaging technologies. The scientific motivation for using phase measurements and imaging technologies is derived from, for example, cellular biology at the sub-micron level which can include, without limitation, imaging origins of dysplasia, cellular communication, neuronal transmission and implementation of the genetic code. The structure and dynamics of sub-cellular constituents cannot be currently studied in their native state using the existing methods and technologies including, for example, x-ray and neutron scattering. In contrast, light based techniques with nanometer resolution enable the cellular machinery to be studied in its native state. Thus, preferred embodiments of the present invention include systems based on principles of interferometry and/or phase measurements and are used to study cellular physiology. These systems include principles of low coherence interferometry (LCI) using optical interferometers to measure phase, or light scattering spectroscopy (LSS) wherein interference within the cellular components themselves is used, or in the alternative the principles of LCI and LSS can be combined to result in systems of the present invention.

Patient-specific instruments for preparing bones for receipt of orthopedic prostheses, such as the distal tibia and the talus in a total ankle arthroplasty (TAA) procedure. A tibial guide and a talar guide are manufactured based on patient-specific anatomical data obtained using imaging technology, and each guide includes a surface conforming to selected anatomical surfaces or regions of the tibia or talus, respectively. Each guide includes at least one cut referencing surface, such as a cut slot, to guide a resection, and may also include a guide aperture sized to guide a reaming tool for reaming the distal tibia or talus. The guides may also include pin holes positioned within a periphery defined by the cut referencing surfaces such that, when the resections are made and the resected tibial bone portion or talus bone portion is removed, the guide and its associated pins are removed along with the resected bone portion. The guides may be designed to ensure that a proximal resected surface of the distal tibia is parallel to a resected surface of the talus, with the parallel resected surfaces perpendicular to the anatomical axis of the distal tibia.

A system and method for improving a surgeon's vision by overlaying augmented reality information onto a video image of the surgical site. A high definition video camera sends a video image in real time. Prior to the surgery, a pre-operative image is created from MRI, x-ray, ultrasound, or other method of diagnosis using imaging technology. The pre-operative image is stored within the computer. The computer processes the pre-operative image to decipher organs, anatomical geometries, vessels, tissue planes, orientation, and other structures. As the surgeon performs the surgery, the AR controller augments the real time video image with the processed pre-operative image and displays the augmented image on an interface to provide further guidance to the surgeon during the surgical procedure.

The present invention relates to an apparatus, method, software algorithm and system for evaluating plants for conditions or characteristics. In one aspect, the method can include imaging at least a portion of the plant and evaluating the image for discriminating condition(s) or characteristic(s) of interest. In one example, soybean roots are imaged and the image is evaluated to discriminate between soybean cyst nematode (SCN) cysts and the plant roots to count the number of SCN cysts for the plant. In another embodiment, a plant is illuminated by a ultra-violet radiation selected to cause photo-induced fluorescence of a target, e.g. SCN cysts. The fluorescence emitted is collected and analyzed to discriminate between the target and the remainder of the plant.
