Ultrasonic estimation of separation change between membranes in a human thorax phantom oriented to pleural effusion detection

Abstract

The objective of this paper is to develop an ultrasound signal processing technique suitable to measure changes in distance between two membranes that simulate the pleural membranes in a basic human thorax phantom. The proposed technique is based on the correlation and autocorrelation methods. Obtaining an accuracy of 96.83 percent compared to those measures obtained with a caliper.
