摘要： Saturation of received signals and generation of artifacts that are associated with tap concentration are prevented from occurring even if the differences in the delay amount between each of transducers are small. The ultrasound diagnosis apparatus comprises a plurality of ultrasound transducers, a plurality of taps, a delay amount calculator, a channel distributor, and a delay processor. The delay amount calculator calculates a first delay amount. The channel distributor specifies the minimum delay amount and the maximum delay amount from the first delay amount. Further, the channel distributor divides the range from the minimum delay amount to the maximum delay amount by the number of taps, and relates each to a tap. The channel distributor also inputs a signal output from an ultrasound transducer to the tap related to the divided range including the corresponding first delay amount. The delay processor relates the tap to a previously set second delay amount, and conducts delay processing on the signal input in each of the taps based on the related second delay amount.

摘要翻译： 即使每个换能器之间的延迟量的差异小，也防止发生与抽头浓度相关联的接收信号的饱和度和伪像的产生。 超声波诊断装置包括多个超声波换能器，多个抽头，延迟量计算器，通道分配器和延迟处理器。 延迟量计算器计算第一延迟量。 信道分配器从第一延迟量指定最小延迟量和最大延迟量。 此外，信道分配器将最小延迟量的范围从最大延迟量除以抽头数，并且将每一个与抽头相关联。 信道分配器还将从超声换能器输出的信号输入到包括相应的第一延迟量的分频范围内的抽头。 延迟处理器将抽头与先前设置的第二延迟量相关联，并且基于相关的第二延迟量对每个抽头中的信号输入进行延迟处理。
