ABSTRACT:
Ultrasound information for B-mode and CW Doppler mode use the same digital beamformer. Due to sigma-delta conversion or over sampling, sufficient dynamic range is provided for the desired bandwidth. By mixing the input ultrasound information to base band before conversion, additional dynamic range may be provided. The electrical impedance may be better matched to elements by connecting a different number of sigma-delta converters to an element. Elements with lower impedance may be connected to a plurality of sigma-delta converters. To increase the aperture size for elements with a higher impedance, the same sigma-delta converters may be used as separate receive beamformer channels without the summation.
