Embodiment Construction

[0016] Certain embodiments can be found in methods and systems that can be used in an exemplary ultrasound system that provides coherent compound motion detection using channel coherence and transmit coherence. Various implementations have the technical effect of improving ultrasound images by accurately determining whether pixels in the ultrasound images are subject to phase cancellation due to motion.

[0017] The foregoing summary, as well as the following detailed description of certain embodiments, are better understood when read in conjunction with the accompanying drawings. To the extent that the figures illustrate the functional blocks of various embodiments, these functional blocks are not necessarily indicative of the division between hardware circuitry. Thus, for example, one or more functional blocks (eg, a processor or memory) may be implemented in a single piece of hardware (eg, a general-purpose signal processor or random access memory block, hard disk, etc.) or...

Abstract

The invention discloses a method and system for coherent compound motion detection using channel coherence and transmit coherence. The disclosure provides for a method for generating an ultrasound image that includes transmitting, by a plurality of transmitters in a transducer, at least two transmit beams at different angles, where at least parts of the transmit beams cover an overlapping region, and receiving, by a plurality of sensors of the transducer, reflected signals of the transmit beams. The method further comprises calculating channel coherence for the received signals to produce one or more channel coherence images, and calculating transmit coherence for the received signals to produce one or more transmit coherence images. The information from at least one of the channel coherence images and at least one of the transmit coherence images are combined to identify moving objects. The received signals from different transmits in overlapping regions are then processed to produce a final image that is compensated for the moving objects.

Description

technical field [0001] Certain embodiments relate to ultrasound imaging. More specifically, certain embodiments relate to methods and systems for providing coherent composite motion detection using channel coherence and transmit coherence. Background technique [0002] Ultrasound imaging is a medical imaging technique used to image organs and soft tissues in the human body. Ultrasound imaging uses real-time, non-invasive, high-frequency sound waves to produce a series of two-dimensional (2D) images and / or three-dimensional (3D) images. [0003] During ultrasound-based imaging of a patient, the image quality of the patient may sometimes be reduced. Therefore, much effort is required to provide accurate and clear images. [0004] Further limitations and disadvantages of conventional and traditional approaches will become apparent to those skilled in the art by comparing such systems with some aspects of the disclosure set forth in the remainder of this application with refe...
