ULTRASOUND SYSTEM FOR CONTROLLING THE POWER OF TRANSMITTING PULSE SIGNAL USING MULTIPLE PULSER, CAPABLE OF FORMING A PSEUDO ARBITRARY TRANSMITTING WAVEFORM

摘要

PURPOSE: An ultrasound system for controlling the power of transmitting pulse signal is provided to improve apodiation effect by increasing weighting steps which are limited by a transmitting control clock and a transmitting frequency.;CONSTITUTION: An ultrasound probe(110) includes a plurality of conversion-elements. The conversion-elements transmit ultrasound signal to an object and receives ultrasound echo signal which is reflected from the object in order to form receiving signal. A transmitting unit(120) includes a multiple pulser which forms transmitting pulse signal to be applied each conversion-element. The transmitting unit applies a weighting value for adjusting the power of the transmitting pulse signal based on the number of pulsers, a transmitting control clock, and a transmitting frequency.;COPYRIGHT KIPO 2010
