Abstract
In this work the authors address some of the problems associated with the optimization of CW transducers to be used via the suprasternal notch window (SSN) to insonate the aortic arch. Firstly, the geometrical characteristics of the anatomical region of interest are evaluated. Secondly, based on these characteristics, the required interrogation field (RIF) is defined and used as a criterion for classifying the suitability of any probe used in this application. Thirdly, the interrogation fields of two commercial probes are evaluated based on this criterion. Finally, a design methodology is proposed and implemented for defining a source and receiver distribution that produces an interrogation field with improved coverage of the RIF.
