Abstract: Systems, devices, and methods for performing ultrasound imaging are provided to advantageously determine the viscosity of an anatomy. According to one embodiment, a system for determining a viscosity of an anatomy includes an ultrasound transducer, a vibration source, and a processing system in communication with the ultrasound transducer and the vibration source. The processing system is configured to activate the vibration source to induce in the anatomy a first shear wave at a first frequency and a second shear wave at a second frequency, activate the ultrasound transducer to obtain ultrasound data representative of the anatomy that exhibits the first shear wave and the second shear wave, determine a first wave speed of the first shear wave and a second wave speed of the second shear wave, and determine the viscosity of the anatomy by comparing the first wave speed and the second wave speed.

Abstract: The present invention relates to an ultrasound elastography system (10) for providing an elastography measurement result of an anatomical site (32) a corresponding method. The system (10) is configured to visualize a suitability for shear wave elastography of the region of interest (33) to the user within the ultrasound image (52) and/or to recommend an elastography acquisition plane (48, 50) for conducting shear wave elastography to the user. By this, proper selection of a location for an elastography measurement may be supported.

Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.
