Abstract
By using a novel structure of a beamformer which produce data for multiple receive scanlines in a time multiplexed manner, the size of the delay memory is reduced. An ultrasound receive beamforming apparatus for processing signals received from an array of transducers, comprises: a plurality of beamforming devices for applying delays to data samples of M channels. Each of said beamforming devices includes: a predetermined number of per-channel delay elements which provide first delays to the data samples of M channels, to provide delayed data per each channel and per each receive beam, first adders for adding the delayed data of not less than 2 channels provided from the per-channel delay elements, and multi-channel delay elements which provide second delays to the outputs of the first adders.
