System and method for significant dust detection and enhancement of dust images over land and ocean
InactiveUS20050012035A1Enhanced signalHigh sensitivityRadiation pyrometryMaterial analysis by optical meansWater useDust detection
A new processing capability for dust enhancement over land or water using image data from the Sea-viewing Wide Field of View Sensor (SeaWiFS) has been developed for Naval meteorology / oceanography (MetOc) operations support. The data are captured via direct broadcast high-resolution picture transmission (HRPT) at Navy Regional Centers in Rota, Bahrain, and Yokosuka, and processed at the Naval Research Laboratory in Monterey. The raw data are calibrated, corrected for missing lines and clutter, corrected for molecular scatter contamination, and enhanced through multispectral combination to yield value added products. The processing has been automated completely such that products, generated upon receipt of data, are hosted upon a password protected website typically 60 to 90 minutes from time of initial capture. This invention summarizes the SeaWiFS instrument capabilities, the protocol followed for automated near real-time processing, a physical basis for the NRL enhancements, and specific examples of the products with extension to over-land dust enhancement as enabled by MODIS. It closes with a glimpse of the potential utility of these products from the perspective of the warfighter.

Method of analyzing multi-sequence MRI data for analysing brain abnormalities in a subject
The present invention, referred to as Oasis is Automated Statistical Inference for Segmentation (OASIS), is a fully automated and robust statistical method for cross-sectional MS lesion segmentation. Using intensity information from multiple modalities of MRI, a logistic regression model assigns voxel-level probabilities of lesion presence. The OASIS model produces interpretable results in the form of regression coefficients that can be applied to imaging studies quickly and easily. OASIS uses intensity-normalized brain MRI volumes, enabling the model to be robust to changes in scanner and acquisition sequence. OASIS also adjusts for intensity inhomogeneities that preprocessing bias field correction procedures do not remove, using BLUR volumes. This allows for more accurate segmentation of brain areas that are highly distorted by inhomogeneities, such as the cerebellum. One of the most practical properties of OASIS is that the method is fully transparent, easy to implement, and simple to modify for new data sets.

Method and system for high speed measuring of microscopic targets
InactiveUS20050174580A1Overcome limitationsBeam/ray focussing/reflecting arrangementsPhotoelectric discharge tubesDigital dataTriangulation
A system including confocal and triangulation-based scanners or subsystems provides data which is both acquired and processed under the control of a control algorithm to obtain information such as dimensional information about microscopic targets which may be “non-cooperative.” The “non-cooperative” targets are illuminated with a scanning beam of electromagnetic radiation such as laser light incident from a first direction. A confocal detector of the electromagnetic radiation is placed at a first location for receiving reflected radiation which is substantially optically collinear with the incident beam of electromagnetic radiation. The system includes a spatial filter for attenuating background energy. The triangulation-based subsystem also includes a detector of electromagnetic radiation which is placed at a second location which is non-collinear with respect to the incident beam. This detector has a position sensitive axis. Digital data is derived from signals produced by the detectors. In this way, data from at least one triangulation-based channel is acquired in parallel or sequentially with at least one slice of confocal image data having substantially perfect temporal and spatial registration with the triangulation-based sensor data. This allows for fusion or further processing of the data for use with a predetermined measurement algorithm to thereby obtain information about the targets.

The disclosed technology brings histopathology into the operating theatre, to enable real-time intra-operative digital pathology. The disclosed technology utilizes confocal imaging devices image, in the operating theatre, “optical slices” of fresh tissue—without the need to physically slice and otherwise process the resected tissue as required by frozen section analysis (FSA). The disclosed technology, in certain embodiments, includes a simple, operating-table-side digital histology scanner, with the capability of rapidly scanning all outer margins of a tissue sample (e.g., resection lump, removed tissue mass). Using point-scanning microscopy technology, the disclosed technology, in certain embodiments, precisely scans a thin “optical section” of the resected tissue, and sends the digital image to a pathologist rather than the real tissue, thereby providing the pathologist with the opportunity to analyze the tissue intra-operatively. Thus, the disclosed technology provides digital images with similar information content as FSA, but faster and without destroying the tissue sample itself.

Method and system for calibrating ink ejection elements in an image forming device
By implementation of an optical scanner, the calibration of printheads of a printing mechanism may be performed in a relatively short period of time as compared to known techniques. In one respect, the time required to perform the calibration may be substantially reduced by virtue of the relatively wide field of view of the optical scanner. The relatively wide field of view generally enables for the scanning of test patterns to be performed with a relatively fewer number of scanning passes, thus reducing the time required to perform the scanning operations as well as the calibration operations. In addition, the scanning operations may yield relatively more accurate results as compared to known scanning operations. In one respect, optical scanners are capable of detecting smaller drops of ink on print media by virtue of their higher resolution capabilities. In another respect, all of the printed colors may be accurately detected through implementation of a red, green, blue (RGB) charge coupled device (CCD) contained in the optical scanners.
