摘要： A method and system for three dimensional crystallographic grain orientation mapping illuminates a polycrystalline sample with a broadband x-ray beam derived from a laboratory x-ray source, detects, on one or more x-ray detectors, diffracted beams from the sample, and processes data from said diffracted beams with the sample in different rotation positions to generate three dimensional reconstructions of grain orientation, position, and/or 3-D volume. A specific, cone beam, geometry leverages the fact that for a point x-ray source with a divergent beam on reflection of an extended crystal grain diffracts x-rays such that they are focused in the diffraction plane direction.

摘要： An optical coherence tomography system uses an optical source that comprises a series of gain waveguides that generate light at the frequencies at which the interference signal is to be sampled. In this way, the optical source generates a discretely tuned optical signal. This has the advantage that the tuning can be directly controlled by a controller that is also used to synchronize the sampling of the interference signal. This avoids the need for separate frequency clock synchronization. In embodiments, the gain waveguides are fabricated from one or more semiconductor edge emitting bars. In some implementations, the gain waveguides comprise periodic structures that define the frequency of operation of the waveguide. However in other implementations, the combiner comprises a dispersive element, such as a diffractive grating, that provides frequency specific feedback to each waveguide.

摘要： A basic component of Computer-Aided Detection systems for digital mammography comprises generating candidate mass locations suitable for further analysis. A component is described that relies on filtering either the background image or the complementary foreground mammographic detail by a purely signal processing method on the one hand or a processing method based on a physical model on the other hand. The different steps of the signal processing approach consist of band-pass filtering the image by one or more band pass filters, multidimensional clustering, iso-contouring of the distance to centroid of the one or more filtered values, and finally candidate generation and segmentation by contour processing. The physics-based approach also filters the image to retrieve a fat-corrected image to model the background of the breast, and the resulting image is subjected to a blob detection filter to model the intensity bumps on the foreground component of the breast that are associated with mass candidates.

The balanced detector system includes at least two optical detectors that receive interference signals. An electronic amplifier system installed within the optoelectronic package amplifies an output of at least two optical detectors. Also disclosed is an integrated optical coherence tomography system. Embodiments are provided in which the amplifiers, typically transimpedance amplifiers, are closely integrated with the optical detectors that detect the interference signals from the interferometer.

摘要： The position of the sample is measured and used to correct for any off-axis motion during tomography using x-ray projection microscope system with a rotation stage system. The position is sensed using a precision-machined, low-CTE gold-coated cylinder or disc and three to five capacitive distance sensors. The correction can then be performed purely as image processing in software, by applying an appropriate shift in X and Y of the captured x-ray projections. A calibration is often necessary for each system (gold disc plus sensors plus sample stage) to account for any machining errors of the gold disc or positioning errors of the capacitive sensors. This calibration should also be repeated whenever any maintenance is performed on the metrology setup.

摘要： A Markov Random Field (MRF)-based technique is described for performing clustering of images characterized by poor or limited data. The proposed method is a statistical classification model that labels the image pixels based on the description of their statistical and contextual information. Apart from evaluating the pixel statistics that originate from the definition of the K-means clustering scheme, the model expands the analysis by the description of the spatial dependence between pixels and their labels (context), hence leading to the reduction of the inhomogeneity of the segmentation output with respect to the result of pure K-means clustering.
