TLDR
A technique based on digital speckle pattern interferometry is described to obtain cardiac displacement pattern during entire cardiac cycle, which may provide useful information on cardiac function in health and diseases.Abstract:

On the UWB medical radars working principles
TL;DR: In the last 20 years, a lot of research activity has been carried out on UWB radar in medicine but in spite of the many working examples presented, the authors are still convinced that a solid explanation of the operation of such radars is lacking.

Reconstruction of sequential cardiac in-plane displacement patterns on the chest wall by laser speckle interferometry
Megha Singh,G. Ramachandran +1 more
TL;DR: Time-average speckle interferometry has been applied to obtain displacement patterns on the chest wall produced by cardiac action, in the absence of breathing, during various phases of the cardiac cycle and the functional details of the normal heart are outlined.

Imaging of chest motion due to heart action by means of holographic interferometry
TL;DR: A method for visualising and mapping the chest-surface movements induced by heart action and the localisation of motion maxima and their distribution contain valuable clinical information is initiated.
