An Ultrasound Moving Target Indicator System for Diagnostic Use

An ultrasound system using moving target indicator (MTI) techniques has been developed to provide a different approach to the problem of isolating and presenting echo information arising from dynamic tissue interfaces. The basic MTI procedure accomplishes isolation of moving target information by comparing echo information subsequent to a transmit pulse to the echo information arising from the preceding pulse. Stationary target information is effectively eliminated. In addition, the MTI procedure isolates dynamic target information throughout the volume investigated by the ultrasonic transducer. This feature eliminates the need for rangegating.
