Abstract: This invention provides a system and method for guiding a surgical instrument based on information obtained using enhanced contrast-mode ultrasound. The enhanced information can be added to information or images obtained in one or more imaging modes. Various pieces of information can be combined and composited, including information regarding tumors, blood vessels, location information, confidence levels, and other information, and can be composited into operative imaging.

Abstract: This invention provides a system and method for enhancing images acquired by an ultrasound scanner. The system and method employs novel techniques that are compatible with the real-world constraints (i.e. energy levels, duration of exam, geometries involved, etc.) of imaging in mammalian tissue (e.g. tissues of human organs containing lesions/tumors), while providing the dramatically image quality.

Abstract: This invention provides a system and method for background removal from images acquired by an ultrasound scanner in the presence of molecularly bound contrast agent. The system and method employs novel techniques that are compatible with the real-world constraints (i.e. energy levels, duration of exam, geometries involved, etc.) of imaging in mammalian tissue (e.g. tissues of human organs containing lesions/tumors), while providing the dramatically improved signal clarity required to reliably disambiguate contrast agent from other sources of signal intensity.

Abstract: A synthetic aperture radar guidance system adapted for use in a guided missile is described wherein the frequency of the transmitted pulses changes with time with a chirp slope which varies with range. The time between pulses also changes as a function of range. The desired values of the chirp slope and the interpulse interval are computed for all values within a range of interest and stored. Furthermore, the operating parameters of the SAR are changed as the range changes. The time intervals and frequencies are selected to avoid interruption ambiguities and eclipsing. The phase and frequency of the synthesized signal are controlled to adjust for motion of a vehicle on which the SAR is mounted. The SAR is operated in several modes. In a search mode, the beam of transmitted pulses is steered across a mapping area to form a plurality of patches of the mapping area. The patches are combined into one map of the entire area. Each pixel of the map is compared with a target template until a match is provided.
