A Real-Time Lag-One Coherence Tool for Adaptive Imagmg


Conference Paper

© 2018 IEEE. Ultrasound imaging is the product of numerous pulse sequence and processing design choices, but it is impossible to optimize for every clinical imaging case with a single set of parameters. Many sonographers do not take advantage of even the limited set of controls provided to them during an exam. We have demonstrated that lag-one coherence (LOC), an aperture-domain signal quality metric, reflects image quality in the presence of in vivo clutter effects. This feedback could be useful in adaptively selecting patient-and view-specific optimal parameters. Increased system bandwidth and computing power now make it possible to estimate LOC in real-time. We demonstrate a Verasonics-based platform for real-time temporal correlation and spatial coherence estimation during B-mode imaging at 18 frames per second. Demonstrations of abdominal and cardiac imaging under varying common scanning conditions are presented using the tool.
