摘要： In accordance with embodiments disclosed herein, systems, methods, and computer programs are provided that determine a mechanical property of a subject. An excitation force is applied to a displacement origin within a subject, and a shear wave is generated in response to application of the excitation force. The displacement data indicative of displacement motion at the sample position is sampled by tracking pulses, and the timing of at least one of the tracking pulses is adjusted relative to application of the excitation force. The process continues until a peak displacement of the shear wave for the sample position is determined based upon the displacement data.

摘要： An ultrasound probe analog to digital converter includes an input successive approximation register (SAR) first stage; and an output SAR second stage in communication with the input SAR first stage. The input SAR first stage includes a programmable preamplifier integrated therein for residue amplification. The preamplifier is programmed to alternate between a linear amplifier operating mode and a comparator operating mode.

摘要： An apparatus comprising a convex probe, a receiver and an image generating device. The convex probe includes a number of transducer elements configured to transmit a number of sets of ultrasound signals. Each set of the ultrasound signals includes a non-steered frame and at least one steered frame angled toward the non-steered frame. The receiver is coupled to the probe and configured to receive a non-steered echo frame for the non-steered fame and at least one steered echo frame for the at least one steered frame. The image generating device is coupled to the receiver and configured to generate a non-steered image using the non-steered echo frame and a needle-enhancement image using the steered echo frame and combine the non-steered image and the needle-enhancement image into a compound image.
