    摘要: Ultrasound signal processing device including: transmitter performing transmission events while varying a focal point; receiver generating, for each transmission event, receive signal sequences for transducer elements; delay-and-sum calculator generating, for each transmission event, a sub-frame acoustic line signal including an acoustic line signal for each measurement point located on target lines passing through the focal point and composing a target line group; and synthesizer combining sub-frame acoustic line signals to generate a frame acoustic line signal. The target lines are straight lines, and any measurement point, on any target line, that is spaced away from the focal point by a predetermined distance or more satisfies a condition that distance between the measurement point and a most nearby measurement point on the same target line is smaller than distance between the measurement point and a most nearby one among measurement points on an adjacent target line.

    摘要: A body movement signal generation unit (60) generates a body movement signal which varies in response to body movement of a test subject as a diagnosis subject on the basis of a reception signal corresponding to a monitoring reception beam obtained from a reception unit (14). A body movement monitoring unit (62) determines the start time of a diagnosis-recommended period in which body movement is minimal by distinguishing between large and small body movements on the basis of the body movement signal obtained from the body movement signal generation unit (60). A control unit (70) executes diagnostic processing from a start time for diagnosis. Through this configuration, it is possible to obtain stable diagnostic information in which the effect of heartbeats is low and that is preferably entirely unaffected by heartbeats.

    摘要: Methods and systems are provided that perform baseband beamforming of ultrasound signals. The methods and systems obtain receive signals from transducers of an ultrasound probe and demodulate the receive signals to obtain complex receive signals having in-phase (I) and quadrature (Q) components. The methods and systems apply time delay and phase correction to the complex receive signals to form delayed complex receive signals before summing the delayed complex receive signals to produce a coherent receive signal. The phase correction includes applying coarse and fine corrections where the coarse correction is calculated as a multiple of a sampling time and the fine correction is calculated as a fraction of the sampling time. The methods and systems apply the coarse and fine corrections contemporaneously by multiplying the complex receive signal by a complex carrier delayed by a multiple of the sampling time and delayed by the fraction of the sampling time.
