Article Synopsis
- The study explores advanced clutter-filtering techniques, specifically using singular value decomposition (SVD) and diverging wave imaging, to measure cardiac flow effectively in a routine clinical setting.
- Challenges include designing smaller ultrasound apertures for better accessibility, managing reduced pulse repetition frequency for deeper imaging, and dealing with stronger tissue motion during the heartbeat that complicates the distinction between blood and clutter signals.
- The proposed solution involves adaptive higher-order SVD (HOSVD) that optimizes the number of tilt angles, allowing for improved separation of blood flow signals from clutter by utilizing a 3-D tensor approach for greater flexibility in threshold selection.
Comparison Between Multiline Transmission and Diverging Wave Imaging: Assessment of Image Quality and Motion Estimation Accuracy.
IEEE Trans Ultrason Ferroelectr Freq Control
October 2019
High frame rate imaging is particularly important in echocardiography for better assessment of the cardiac function. Several studies showed that diverging wave imaging (DWI) and multiline transmission (MLT) are promising methods for achieving a high temporal resolution. The aim of this study was to compare MLT and compounded motion compensation (MoCo) DWI for the same transmitted power, same frame rates [image quality and speckle tracking echocardiography (STE) assessment], and same packet size [tissue Doppler imaging (TDI) assessment].
