Embodiment Construction

[0034] The present invention will be described with reference to specific embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims. The drawings described are only schematic and non-limiting. In the drawings, the size of some of the elements may be exaggerated and not drawn on scale for illustrative purposes.

[0035] First refer to figure 2 , shows in block diagram form an ultrasound system constructed in accordance with some embodiments of the present invention.

[0036] The ultrasound probe 10 has a one-dimensional or two-dimensional array 12 of transducer elements for transmitting and receiving ultrasound signals. The transducer array 12 can scan a two-dimensional (2D) plane by transmitting a beam on a single plane in the body and receiving returning echo signals, and can also be used to scan in different directions and / or planes along a volumetric (3D) region of the body. A beam is emitted to scan a volumetric ...

Abstract

The present invention proposes an ultrasound imaging system and method for measuring a property of a region of interest in a subject by using shear wave, wherein an ultrasound probe is configured to sequentially transmit, to each of a plurality of focal spots (320, 322, 324) in the region of interest, a push pulse (310, 312, 314) for generating a shear wave (330, 332, 334), each of the plurality of focal spots having a mutually different depth value (z1, z2, z3), and to receive ultrasound echo signals adjacent (350, 352, 354) to each of the plurality of focal spots; a shear wave detector is configured to derive, for each of the plurality of focal spots, a first parameter indicating a property of the generated shear wave, based on the received ultrasound echo signals; and a property estimator is configured to estimate a second parameter indicating the property of the region of interest as a function of the derived first parameters.

Description

technical field [0001] The present invention relates to an ultrasound system and method for making measurements using shear waves, and more particularly to measuring properties of regions of interest in a subject using shear waves. Background technique [0002] Mechanical changes in biological tissues are associated with pathological changes. For example, tissue viscosity, tissue stiffness (also called elasticity), and tissue attenuation coefficient (including tissue longitudinal wave attenuation and tissue shear wave attenuation, where shear wave attenuation is also called shear wave attenuation) are important physical parameters in clinical practice. Various devices have been developed to remotely interrogate the mechanical properties of tissue using the radiation force of an ultrasound beam to remotely apply force to a tissue region within a subject such as a patient (acoustic radiation force, also known as a push pulse or pushes the beam) to cause tissue deformation. A...
