Embodiment Construction

[0029] In the following description, for purposes of explanation and not limitation, specific details are set forth (eg, specific architectures, interfaces, techniques, etc.) in order to provide a thorough understanding of the concepts of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In like manner, the text in this specification is directed to example embodiments as shown in the drawings and is not intended to limit the claimed invention beyond the limitations expressly included in the claims. For the sake of simplicity and clarity, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] As detailed above, prior art systems that employ PI submodes, AM submodes, and AMPI submodes to differentiate tissue from blood flow and perfusio...

Abstract

A particular sequence of ultrasound transmissions and corresponding echo receptions enables the production of Amplitude Modulated (AM) and Amplitude Modulated Phase Inverted (AMPI) signals that are temporally balanced. Temporal balancing significantly reduces tissue artifacts caused by movement of tissue during acquisition of the ultrasound echoes. Additionally, in combining the selected echo signals to produce the AM and AMPI signals, and optionally a Phase Inverted (PI) signal, each of the echo signals is equally weighted to facilitate an amplitude balance that avoids different echoes affecting the produced AM, AMPI, and PI signals differently.

Description

technical field [0001] The present invention relates to the field of contrast-enhanced ultrasound (CEUS) imaging, and more particularly to methods and systems employing advanced pulse sequences that combine the advantages of multiple CEUS pulse protocols. Background technique [0002] Ultrasound images are created by transmitting pulses of ultrasound at varying amplitudes and frequencies, receiving echoes corresponding to each transmitted pulse, and processing the echoes to create an image. Typically, an ultrasound contrast agent is injected into a subject's blood vessels to enhance visualization of blood flow through the blood vessels and perfused tissue. Ultrasound contrast agents typically contain microbubbles that greatly increase the intensity of the signal emanating from the blood and thus preferentially enhance the signal emanating from the blood relative to the signal received from tissue that is not perfused with blood. [0003] However, ultrasound signals providin...
