ULTRASOUND DIAGNOSTIC DEVICE AND METHOD CAPABLE OF INCREASING FRAME RATE WITH DIVDED TRANADUCER GROUP

摘要

PURPOSE: A number of converter groups is multiplied proportionally to the number of ultrasonic diagnostic equipment for scan being proceed to the converter group partitioning and multiplying the frame rate and method is the scan line or converters. The frame rate is kept with the fixed level. CONSTITUTION: It changes the transmission signal into the ultrasonic signal and the probe(110) transmits a message according to the transmission scan line in object. Probe comprises a plurality of converters for changing the ultrasonic signal received from object into the received signal. The transmission beam former(120) offers the transmission signal in which the time delay is especially reflected the converter of each group. It samples the received signal inputted from converter to the fixed rate and the receive beam former(130) changes into the digital signal.
