Embodiment Construction

[0019] Solid tissue regions may allow for more accurate measurements of shear wave velocity. Other types of regions, such as fluids or fluid tissue, may be less accurately measured for shear wave velocity. Areas of interest may include fluid (eg, blood or urine), bone, and tissue. Tissue may comprise fluid-like tissue (ie, fluid tissue) or solid tissue. Solid tissue includes muscle, fat, organs, or other structures that have relatively more elastic characteristics than fluid and bone. Cysts or other tissue structures can have a high fluid content, resulting in less reliable shear information.

[0020] When both solid and fluid tissues are excited by the impulsive force, both tissues are displaced. The nature of the displacement distribution may differ over time depending on the type of tissue. The displacement in solid tissue is determined by the shear wave equation, while the displacement in fluid tissue is determined by the Navier-Stokes equation. The resulting displace...

Abstract

The invention relates to visualization of related information in ultrasonic shear wave imaging. Information related shear calculation is also displayed (44) in the ultrasonic shear wave imaging (40). Information more than the shear wave imaging is provided for diagnoses. Information for determining the quality or variation of shear is also displayed (44). The additional information can help a user to determine whether the shear information indicates tissue features or unreliable shear calculation.

Description

[0001] related application [0002] This patent document claims priority under 35 USC § 119(e) to the filing date of Provisional US Patent Application Serial No. 61 / 599,785, filed February 16, 2012, which is hereby incorporated by reference. Background technique [0003] This embodiment relates to ultrasound imaging. In particular, ultrasound shear wave imaging can be improved. [0004] Shear wave velocity information may be useful for diagnostic purposes. Shear wave information indicates tissue properties in addition to acoustic impedance (eg, B-mode) and Doppler (eg, flow mode) imaging. However, the complexity of shear wave propagation in tissue can lead to significant errors. For example, shear wave velocity may be seldom determined precisely for fluids or fluid tissues, resulting in seemingly arbitrary values. Contents of the invention [0005] By way of introduction, the preferred embodiments described below include methods, instructions, and systems for visualizat...
