Quantitative approaches to improve lung ultrasound (LUS) vertical artifacts (VA) interpretation using total signal intensity (ITOT) are not widely available for clinical practice. In this study, we aimed i) develop a mathematical algorithm extract ITOT as post-hoc LUS analysis and ii) confirm utility by conducting laboratory VA research an in vitro model with different acoustic channels. The was extracted from static conventional imaging recorded models after varying the amount of water...
The aim of the work described here was to analyze relationship between change in ultrasound (US) settings and vertical artifacts' number, visual rating signal intensity METHODS: An vitro phantom consisting a damp sponge gelatin mix created simulate artifacts. Furthermore, several US parameters were changed sequentially (i.e., frequency, dynamic range, line density, gain, power image enhancement) after acquisition. Five experts rated artifacts for number quality. In addition, artifact score...
