  • Publication number: 20180098750
    Abstract: Methods and systems are provided for ultrasound transducers with variable pitch. In one embodiment, an ultrasound probe comprises a plurality of transducer elements arranged in an array, wherein a pitch between adjacent transducer elements increases from a first pitch in a center of the array to a second pitch at an edge of the array, and wherein the pitch gradually varies between the first pitch and second pitch for transducer elements positioned between the center and the edge. In this way, an ultrasound probe can be operated in multiple modes while avoiding image artifacts caused by an abrupt change in pitch.

  • Publication number: 20180098753
    Abstract: Methods and systems are provided for ultrasound multiplexing. In one embodiment, a system comprises: an ultrasound probe comprising a transducer array and a multiplexer, wherein for a first signal and a second signal originating at the transducer array, the multiplexer multiplexes a sum signal and a difference signal formed from the first and the second signals into a multiplexed signal; and a console coupled to the ultrasound probe via a cable, the console including a processor, wherein the console receives the multiplexed signal via the cable, and wherein the processor generates an image from the first signal and the second signal recovered from the multiplexed signal. In this way, the number of processing channels can be reduced, thereby enabling a smaller ultrasound device with less hardware, while also avoiding signal degradation from channel crosstalk and transmission variation.

  • Patent number: 8582865
    Abstract: Systems and methods are presented for increasing the frame rate of real-time 3D ultrasound imaging. In one embodiment, the frame rate for generating a pseudo-shaded 2D projection image may be increased by controlling the image reconstruction process. Rather than beamforming, scan converting, and interpolating a 3D voxelized data set of an entire scanned volume, only samples required for generating the 2D projection image may be reconstructed. The element data measured from each transducer array element may be combined to directly reconstruct those 3D image samples required by the volume rendering algorithm to generate the 2D projection image.
