This study is concerned with the direct problem of Electro Cardiometry (ECM) technique, and the associated thoracic electrical bioimpedance (TEB). We present a mathematical model for the hemodynamic of the aorta, the change in the electrical conductivity of the blood, and the electrical field problem equivalent to the ECM procedure. Having in view that anatomy plays a key role in investigating the...
There is an outstanding growing interest in developing numerical methods and tools to investigate the hemodynamic of the arterial flow, and to understand its interaction with the anatomic structural system. As arteries morphology is complex and patient-related, medical data based reconstruction of the geometry may be utilized to generate realistic computational domains. Numerical methods and image-based...
A low-cost device using diffuse optical imaging (DOI) for measuring in vivo hemodynamic changes in the spinal cord has been developed. The proposed system is aimed at monitoring for the first time real-time hemodynamic changes associated with intraspinal rhythmic motor activity monitored by electroneurogram (ENG) evoked in paralyzed cats (fictive locomotion). The device contains the emitting and collecting...
