Title:
受信ビーム生成器システムにおけるベースバンド・プロセッサのための方法及び装置
Document Type and Number:
Japanese Patent JP4203834
Kind Code:
B2
Abstract:
The multi-beam baseband processor for making post-beam formation adjustments to the complex (in-phase/quadrature) pre- detection scan line samples acquired from a receive beam former (R-100) of an ultrasound system (R-20), includes a finite impulse response (FIR) filter and a programmable complex multiplier. The programmable filter performs signal shaping and sample rate conversion. The signal shaping compensates for transducer and analogue signal path responses, to increase signal to noise ratio (SNR) by rejecting out of band noise frequencies, to operate as a matched filter to the transmitted waveform shape, and act as both a smoothing and anti-alias filter during rate conversion operation.
