Abstract: One aspect of the present invention is a method for reconstructing computed tomographic (CT) images. The method includes generating a plurality of projection data, calculating a plurality of base weights using the projection data for each series of images to be reconstructed, storing the base weights in an external memory, and applying a z-smoothing module to the base weights to determine a plurality of final weights. The view weighting process then includes applying the final weights to the projection data for each image.

Abstract: A method of secure remote control by voice wherein the digitization and speech recognition functions are separated, which involves receiving an audible voice password in a remote controller, digitizing the voice password, and transmitting the digitized voice password and an ID from the controller to a base station. The method also includes confirming the ID and the password in the base station, receiving an audible voice command in the controller, and digitizing the command. The method still further includes transmitting the digitized command from the controller to the base station, confirming the command to indicate transmission of a desired control signal by the base station, and transmitting the control signal from the base station in response to the command.
