Abstract: A region-growing method for identifying nodules in an anatomical volume segments a 3-D image volume by controlled voxel growth from seed points. The process is based on creation and use of a distance map for tracking the distance of vessel voxels from a predetermined location. A volume map is created that identifies the largest sphere that can pass between a voxel and a predetermined location without touching a non-vessel voxel. The ratio between the distance map and the volume map is analyzed to find regions more likely to contain nodules, the features of which can be extracted or otherwise highlighted.

Abstract: A computer-aided diagnostic method and system provide image annotation information that can include an assessment of the probability, likelihood or predictive value of detected or identified suspected abnormalities as an additional aid to the radiologist. More specifically, probability values, in numerical form and/or analog form, are added to the locational markers of the detected and suspected abnormalities. The task of a physician using such a system as disclosed is believed to be made easier by displaying markers representing different regions of interest.

Abstract: A medical image is analyzed using an algorithm requiring input parameters. Values of the input parameters are derived from metadata, indicating properties of the medical image. For example, the metadata may indicate the type of image acquisition device or settings used to create the medical image. In another example, the metadata may relate to the patient upon whom the image is based. This allows optimum values to be selected for the parameters.

Abstract: A computer-aided diagnostic (CAD) method and system provide image annotation information that can include an assessment of the probability, likelihood or predictive value of the CAD-detected suspected abnormalities as an additional aid to the radiologist. More specifically, probability values, in numerical form and/or analog form, are added to the locational markers of the CAD-detected suspected abnormalities. The task of a physician using a CAD system is believed to be made easier by displaying two different markers representing different probability thresholds. An additional threshold can be used to display “extra view markers” as an additional aid or guide to the radiologic technician to take extra views of a patient before the patient is released or discharged. A control device is added to allow the user to select and vary the probability threshold for the display of locational markers.

Abstract: A network analyzer measurement method adaptively adjusts measurement parameters of the network analyzer, based on a set of measurements of a device under test (DUT) and according to a user-specified limit contour, maximum permissible measurement error or other decision criteria. Measurement speed of the network analyzer is optimized by performing subsequent measurements on the DUT using the adjusted measurement parameters. Measurement bandwidth, the number of measurement sweeps or the frequency location of stimulus points of the analyzer is optimized when characterizing the DUT.

Abstract: Disclosed is a method of making a printed circuit board by exposing in a circuit pattern the polymeric surface of a conductive substrate coated with a polymer selected from the group consisting of polyimides, polyamide-imides, polyester-amide-imides, polysulfones, polyphenylene sulfides, and polyphenylene oxides, to an ion beam at an energy of about 50 KeV to about 2 MeV and a fluence of about 10.sup.15 to 10.sup.18 ions/cm.sup.2. The surface is then wet blasted and the portions of the polymeric surface that have been exposed to the ion beam are electrolessly plated with a metal such as nickel or copper. Also disclosed is a coated substrate comprising a metal or conductive surface and an imide polymeric coating on the surface which can be electrophoretically deposited, a portion of which has been exposed to an ion beam.

A steel surface containing relatively high levels of nitrogen and having a surface film containing carbon is implanted with high energy ions. Overlapping layers enriched in carbon and nitrogen are formed beneath the surface and provide the steel with a surface that has improved wear and friction characteristics.

Abstract: Disclosed is a method of immobilizing nuclear waste in glass. A composition is prepared of 60 to 100% of a hydrolyzed glass-forming silicon compound and up to about 40% of a glass-forming aluminum compound. About 1 to about 50% liquid nuclear waste and up to about 10% solid nuclear waste is mixed into the composition. The composition is heated at about 200.degree. to about 500.degree. C. to drive off water and organics, with the resulting vitreous product totally containing the nuclear waste. Finally, this product can be sintered at about 800.degree. to about 900.degree. C. to reduce porosity, or warm pressed into block form.
