Decoupling and Parameter Extraction Methods for Conical Micro-Motion Object Based on FMCW Lidar

Sensors
Micro-Doppler time–frequency analysis has been regarded as an important parameter extraction method for conical micro-motion objects. However, the micro-Doppler effect caused by micro-motion can modulate the frequency of lidar echo, leading to coupling ...

Renal screening sonography—A comparative study in a Portuguese basic emergency service

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 8-16, March 2025.
Renal sonography screening aids in clinical decision‐making for patients with suspected renal colic. This study intends to compare the accuracy and pertinence of sonographic findings obtained by a sonographer in a Basic Emergency Service (BES) with that of radiologists at Referral Hospital (RH) in Portugal. Renal sonography screening was able to detect

Operational assessment and adaptive selection of micro‐Doppler features

IET Radar, Sonar & Navigation, 2015
A key challenge for radar surveillance systems is the discrimination of ground‐based targets, especially humans from animals, as well as different types of human activities. For this purpose, target micro‐Doppler signatures have been shown to yield high automatic target classification rates; however, performance is typically only given for near‐optimal

Sono‐Vasomics With Super‐Resolution Contrast‐Enhanced Ultrasound (SR‐CEUS) for Characterization of Focal Liver Lesions: A Case Report

Portal Hypertension &Cirrhosis, EarlyView.
ABSTRACT Accurate differentiation between benign and malignant focal liver lesions (FLLs) remains a major diagnostic challenge. Vasomics, an emerging discipline, classifies vascular phenotypes into anatomical, biomechanical, biochemical, pathophysiological, and composite categories. Sono‐Vasomics, the ultrasound‐based subset, leverages super‐resolution
