A simulation based preliminary study to validate the algorithm setup used for construction of M-Mode images of heart has been proposed and facilitates fine tuning of algorithm for measurement of left ventricular parameters.Abstract:
Heart Parameters need to be monitored for diagnosis of cardiac abnormalities. Echocardiography technique is widely used to view 2D image of heart in non invasive method using ultrasound. In practice, echocardiography devices typically use multi-element phased array transducer which involves complex algorithms and computations to develop M-Mode images, which are used to measure parameters by placing the cursors manually. A simple hardware with single element ultrasound transducer has been used to record M-Mode images on a single axis. A simulation based preliminary study to validate the algorithm setup used for construction of M-Mode images of heart has been proposed. This study facilitates fine tuning of algorithm for measurement of left ventricular parameters. Since single element transducer and simple algorithm is used, system is less complex, simple and low cost.read more

TL;DR: This document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases.

Effect of skin impedance on image quality and variability in electrical impedance tomography: a model study
K G Boone,David Holder +1 more
TL;DR: It is concluded that the patient's skin should be abraded to reduce impedance, and measurements should be avoided in the first 10 min after electrode placement, to allow satisfactory images.

TL;DR: The present study has confirmed the presence of total heart volume variation that predominantly occurs in the region of atrioventricular plane movement and on the left side, and may relate to the efficiency of energy use by the heart to minimize displacement of surrounding tissue.
