Abstract: A method for applying a filter component for an analytical tomographic reconstruction technique, e.g. filtered backprojection, used in tomographic comprises providing an algebraic reconstruction algorithm for reconstructing a spatial representation of a volume of interest from a projection data set. It thereby takes into account a geometry of the tomographic imaging. The method also comprises applying the algebraic reconstruction algorithm to a plurality of virtual projection data sets—corresponding with a basis vector of a basis for the projection space—to produce a plurality of reconstructed spatial representations and determining the filter component using the plurality of reconstructed spatial representations, and applying the filter. Applying the analytical reconstruction technique with the determined filter component may inherit beneficial properties from the algebraic reconstruction algorithm, e.g. versatility and robustness to noise, without incurring the associated computational cost.

Abstract: A method for determining a projection angle for use in tomographic imaging comprises obtaining projection data including at least one projection view from at least one projection angle. The at least one projection view is generated by scanning a test object with a tomographic imaging device. Each projection view comprises at least one observation value obtained at least one detection location, providing a plurality of candidate projection angles, for each candidate projection angle, calculating a function value indicative of an amount of information that may be gained by adding to the projection data a further projection view generated by scanning of the test object with the tomographic imaging device from the candidate projection angle, and selecting a candidate projection angle from the plurality of candidate projection angles taking into account the function values. A corresponding system and computer program product also is provided.

Abstract: A method of defining network connection policies, deploying the network connection policies and monitoring all network connections, including an automated real-time analysis and intercepting all connections, and determining whether those network connections are private access connections, or public access connections. If the public access connections are unauthorized, terminating the public access connections in communications port for authorized connections.

Abstract: A method of monitoring all network communications, which includes a real-time analysis and intercepting of all connections, and determining whether those network connections, including all connections across the Internet, are authorized or unauthorized connections. If a connection is unauthorized, the connection may be terminated in a real-time environment and the logical communications port for authorized connections is re-established.

Abstract: A method of programming operating system (O/S) utility C and C++ programs within the Microsoft professional development 32/64-bit parallel threads environment, includes providing a computer unit, which can be a 32/64-bit Microsoft PC O/S, or a 32/64-bit Microsoft Server O/S, a Microsoft development tool, which is the Microsoft Visual Studio Development Environment for C and C++ for either the 32-bit O/S or the 64-bit O/S.

Abstract: A method of monitoring all network communications, including a real-time analysis of intercepting all networked connections and closing those network connections, including all connections across the Internet, except for those specific connections that will function to update a networked computer with new software or updates to existing software.

Abstract: A method of monitoring all network login activity, which includes a real-time analysis of intercepting all network login activity, analyzing network login activity, authenticating network login activity and closing (i.e., terminating) those network login connections that are not authenticated to proceed and access the network.
