Main Goals and Proof Techniquesout its haemodynamics. These are only some of the instances in which imaging was limited in its ability to give a complete non-invasive assessment of cardiac disease. Most of these problems have subsequently been solved by the integration of continuous wave and pulsed Doppler into paediatric imaging

Abstract Graphs and Set SystemsWith Doppler cardiography (Doppler) the velocity and direction of blood flow is measured. Consequently Doppler should be useful in diagnosing heart diseases mainly affecting these parameters. Valvular stenosis (increased velocities) and valvular regurgitation (reversed velocities) are the classical examples of such diseases.

Simple and Efficient Programming with C#e noise which is added to the signal. The theoretical accuracy of any velocity measurement can be expressed using the Woodward’s relation: s. = k/(T. × R.), where s. is the variance of the velocity estimation, R the signal-to-noise ratio and T. the measurement duration. Technical problems are furthe
