Abstract: Analysis of executable binary code is performed without detection by defensive elements embedded within the executable binary code or within a system in which the executable binary code is executing. An identified suspect executable file is disassembled. Statically and dynamically analysis is performed on binary code of the disassembled executable file. An anti-anti-debugging function is implemented by executing program call functions in a manner which avoids detection of a debugging program by the defensive elements embedded within the executable binary code of the anti-debugging function of the executable binary code, thereby avoiding detection by the source of the suspect executable file.

Abstract: A method to increase the image formation speed in a digital ultrasound system including annular array of N elements with a plurality of transmit and receive channels. Selectively dropping one or more transmit or receive channels during image formation reduces the amount of data needed to form an image and thus increases the image formation frame rate. The improved frame rate does result in some reduction in resolution, SNR and potentially DOF, but image quality remains at an acceptable level.
