An ultrasonic method for quantifying the nonlinear shear wave elasticity of a medium, the method comprising the following steps: A1.—collecting a temporal succession of shear wave elasticity data from the medium, A2.—applying, to the medium, a deformation that successively changes according to a predetermined sequence of deformations, during the collection of the shear waves, A3.—observing the actual evolution of deformation, and B.—quantifying the nonlinear elasticity of the medium depending on the temporal succession of data and the evolution of deformation.

Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system comprising a processor circuit in communication with an ultrasound transducer array, the processor circuit configured to receive, from the ultrasound transducer array, a set of images of a three-dimensional (3D) volume of a patients anatomy including an anatomical feature; obtain first measurement data of the anatomical feature in a first image of the set of images; generate second measurement data for the anatomical feature in one or more images of the set of images by propagating the first measurement data from the first image to the one or more images; and output, to a display in communication with the processor circuit, the second measurement data for the anatomical feature.

The invention relates to ultrasound imaging method and apparatus suitable for minimally invasive ultrasound diagnostic devices in cardiac ablation monitoring and in tumor ablation monitoring. The present invention proposes an assembly of forward and side-facing transducers and a system of embedded forward and side-facing transducers in apertures on surfaces of the assembly. This provides control of the acoustic properties of the transducer and improved ablation monitoring when the assembly is incorporated in a medical device.

A medical system includes: an endoscope; an ultrasonic probe; and a control device that is connected to the endoscope and the ultrasonic probe, generates a display image from a captured image acquired by the endoscope, and generates an echo image from an ultrasonic wave acquired by the ultrasonic probe, wherein the control device acquires a first echo image in which a target tissue is displayed on a central axis, acquires a second echo image obtained by scanning a cross section different from the first echo image at a reference position of the ultrasonic probe from which the first echo image was acquired, and compares a central axis of the second echo image with a position of the target tissue in the second echo image.

Methods of processing images, such as ultrasound images, to determine integrity of an implant are described. The method may include receiving an ultrasound image of an implant in a body of a subject; determining one or more characteristics of a surface of the implant based on an intensity of pixels of the ultrasound image; generating a predicted status of the implant based on the one or more characteristics by comparison of the one or more characteristics with a database of image data; and displaying the predicted status of the implant. The implant may be a breast implant, for example, wherein the method is useful for analyzing the presence or probability of extracapsular ruptures, contractures, and combinations thereof.
