ManoUS - Research project

Intravascular manometry by vector Doppler ultrasound

ABSTRACT

ManoUS aims to develop a non-invasive method for assessing the severity of vascular constrictions, particularly in the carotid artery. The aim is to implement an ultrasound measurement to estimate pressure loss in such constrictions, prior to an invasive procedure. To achieve this, using a clinical method, colour Doppler ultrasound, the vector velocity field and relative pressures will be estimated, based on the resolution of an inverse problem. The method will be validated numerically and then in the laboratory on carotid stenosis models, by comparing pressure estimates with reference measurements. The aim is to assess the clinical feasibility of this approach in the carotid bifurcation, with a view to pursuing this project with a more ambitious clinical study.
