摘要： A spherical joint includes a body portion and a blocking portion. The body portion includes a ball portion and a joint portion. The ball portion and the joint portion have an inner surface that links the two portions together in an axial direction and an outer surface opposite to the inner surface. The outer surface of the ball portion includes a spherical surface. The body portion further includes a first section and a second section. Each of the first section and the second section intersects with the inner surface and the outer surface such that the two sections together define a gap. The blocking portion is detachably connected to the body portion and shaped to match the gap, so that the blocking portion blocks the gap to form a hollow spherical joint structure. Further disclosed in the present application are a spherical joint assembly and an ultrasonic imaging device.

An apparatus includes a transducer array with a substrate and a single array comprising individual sub-sets of transducer elements disposed on the substrate, wherein the individual sub-sets are not in physical contact with each other and are serially arranged with respect to each other. The apparatus further includes transmit circuitry that conveys an excitation pulse to the transducer array, receive circuitry that receives a signal indicative of an ultrasound echo from the transducer array, and a beamformer that processes the received signal, generating ultrasound image data.

摘要： Changes in tissue stiffness have long been associated with disease. Systems and methods for determining the stiffness of tissues using ultrasonography may include a device for inducing a propagating shear wave in tissue and tracking the speed of propagation, which is directly related to tissue stiffness and density. The speed of a propagating shear wave may be detected by imaging a tissue at a high frame rate and detecting the propagating wave as a perturbance in successive image frames relative to a baseline image of the tissue in an undisturbed state. In some embodiments, sufficiently high frame rates may be achieved by using a ping-based ultrasound imaging technique in which unfocused omni-directional pings are transmitted (in an imaging plane or in a hemisphere) into a region of interest. Receiving echoes of the omnidirectional pings with multiple receive apertures allows for substantially improved lateral resolution.
