The most frequently used modalities for liver imaging are ultrasonography, CT and MRI. In the past 10 years, important advances have been made in all three techniques. This article focuses on...
This review discusses the basic concepts; compares US and MR-based elastography approaches with respect to acquisition, processing, analysis, and output; and examines comparative performance at diagnosing liver fibrosis, the main clinical application of elastography in the abdomen.
1 lis 2023 · Focusing method for pulse–echo estimation of sound speed in normal and fatty liver. (A) Each element of a phased array ultrasound transducer independently generates an ultrasonic pulse. Pre-specified delays between element firing allows steering and shaping of the ultrasound beam, a process called beamforming.
15 wrz 2024 · Abstract. Liver ultrasound is widely used in clinical practice due to its advantages of non-invasiveness, non-radiation, and real-time imaging. Accurate segmentation of the liver region in...
15 sty 2024 · We demonstrated the feasibility of employing a fully integrated phased array probe for reliable and valid LSM, guided by real-time B-mode imaging of liver anatomy. This system represents the first technical advancement toward point-of-care liver fibrosis assessment.
4 sie 2022 · In this work, we explored such a configuration by combining three commercial phased arrays and tested the improvements achieved by a large aperture with 384 elements and a 10 cm lateral...
1 sie 2013 · Our lab is investigating a histotripsy system integrated with ultrasound image-based motion-tracking algorithms that can dynamically adjust the focal zone of a 2-D phased-array transducer to compensate for respiratory or other motion.
