Abstract:
A method for adjusting transmitted power levels in an ultrasonic imaging system, said method comprising:(a) selecting a first transmitted power level for a first transmit line as a function of a first steering angle associated with the first transmit line;(b) selecting a second transmitted power level for a second transmit line as a function of a second steering angle associated with the second transmit line, said first transmit line situated more centrally than the second transmit line and said second transmitted power level being greater than said first transmitted power level;wherein the first and second transmit lines are separated by an angle of at least 35.degree., and wherein the insonification intensity index for the second transmit line at a given range is no more than X% less than the insonification intensity index for the first transmit line at the given range, where X is less than or equal to 20.
