Abstract: A method and system are provided to report the findings of an expert's analysis of image data. The method and system are based on a reporting system that forms the basis of an image management system that can efficiently and systematically generate image reports, facilitate data entry into searchable databases for data mining, and expedite billing and collections for the expert's services. The expert identifies a significant finding on an image and attaches a location:description code to the location of that finding in order to create a significant finding and an entry into a database. Further descriptions of that finding, such as dimensional measurements, may be automatically appended to the finding as secondary attributes. After the evaluation, the system sorts the findings in the database and presents the findings by prioritized categories. The expert edits and approves a multimedia report which may be delivered by electronic means to an end-user.

Abstract: The present invention relates to a rotationally asymmetric chaotic optical multi-pass cavity useful in optical gas sensing spectroscopy, optical delay lines, and laser amplification systems, for example. The cavity may include a single closed mirror having a light reflective surface that is deformed in two orthogonal directions and more particularly, but not exclusively, in the shape of a quadrupole in both horizontal and vertical planes. The cavity includes a light entry port and a light exit port which may be the same or separate ports, as well as a gas inlet and a gas outlet. The optical path length, the beam divergence rate, and the spot pattern are controlled by selecting the cavity deformation coefficients and the input beam direction to achieve the desired beam path and beam quality.

Abstract: A computer system and a computer-implemented method are provided for interactively displaying a three-dimensional rendering of a structure having a lumen and for indicating regions of abnormal wall structure. A three-dimensional volume of data is formed from a series of two-dimensional images representing at least one physical property associated with the three-dimensional structure. An isosurface of a selected region of interest is created by a computer from the volume of data based on a selected value or values of a physical property representing the selected region of interest. A wireframe model of the isosurface is generated by the computer wherein the wireframe model includes a plurality of vertices. The vertices are then grouped into populations of contiguous vertices having a characteristic indicating abnormal wall structure by the computer. The wireframe model is then rendered by the computer in an interactive three-dimensional display to indicate the populations of abnormal wall structure.

Abstract: A method and system are provided for effecting interactive, three-dimensional renderings of selected body organs for purposes of medical observation and diagnosis. A series of CT images of the selected body organs are acquired. The series of CT images is stacked to form a three-dimensional volume file. To facilitate interactive three-dimensional rendering, the three-dimensional volume file may be subjected to an optional dataset reduction procedure to reduce pixel resolution and/or to divide the three-dimensional volume file into selected subvolumes. From a selected volume or subvolume, the image of a selected body organ is segmented or isolated. A wireframe model of the segmented organ image is then generated to enable interactive, three-dimensional rendering of the selected organ.

Abstract: An ionizer includes a high voltage AC generator, and a planar ion emitter mounted on an insulating substrate and having an array of planar needles that protrude from an edge of the substrate. The high voltage AC generator may be actuated by a switch having a pair of mutually insulated planar contacts located near an edge of the insulating substrate and configured to be contacted by an electrically conductive coil spring. The coil spring is supported by a slider that is moveable toward the ion emitter from an initial position wherein the planar contacts are shorted by the spring so as to actuate the high voltage AC generator. Continued movement of the spring collects dust in its coils while breaking the switch contacts and de-energizing the high voltage AC generator.

Abstract: There is disclosed a method and apparatus for generating data for a two-dimensional image which identifies different classes of property of an imaged subject, this being done by separately rendering volumetric data classified into those different classes and, from all of those separate renderings, choosing one datum for use in the two-dimensional image as an image pixel. This being repeatable for each datum to be used in the two-dimensional image—thereby, for example, to selectively build-up the data for whole of the two-dimensional image as a mixture/combination of different classes of data. The data for the two-dimensional image may be color coded for visually distinguishing data of different classes. Thus when applied to the image enhancement of tissues subjected to contrast agent uptake in patients kinetic information may be incorporated into the volume renderings to enable tissues of different enhancement and kinetic characteristics to be identified as such.

The anti-copying feature may lighten or darken, or both, when copied and may or may not be evident to the human eye. A reader comprising an imager and a processor is for reading the ballot or sheet and for determining whether the ballot or sheet is an original or is a copy, and for determining selections marked thereon. A method for reading the ballot or sheet is for determining from an image of the ballot or sheet whether the ballot or sheet is an original or is a copy, and for determining selections marked thereon.

Abstract: An external fixation assembly includes a plurality of hollow pins that are inserted into a patient's bone. Each pin has an interior bore and a plurality of apertures extending through the pin wall from the bore.

Three-dimensional volume data (34) is formed from a series of two-dimensional images (33) representing at least one physical property associated with the three-dimensional structure, such as a body organ having a lumen.
