Abstract :
A new method for flow velocity mapping of blood is presented here. Instead of the conventional approach of employing two images (velocity sensitive and control) to generate velocity information, in the new method the velocity is determined directly by solving an inverse problem. This technique is an application of single shot - parameter assessment by retrieval from signal encoding (SS-PARSE). Simulations have been done to demonstrate the feasibility of the method. The velocity measurement range of the prototype version is from -50cm/s to 50cm/s, roughly appropriate for future applications in blood flow measurement of carotid arteries.
