GENERATING AN ULTRASOUND DEVICE INTERACTION INDICATOR

Abstract: a system and method for generating an ultrasound device interaction indicator representative of at least an orientation of an ultrasound device () relative to a subject (). an acoustically translucent standoff layer () is positioned between the ultrasound device and the subject. ultrasound echoes received by the ultrasound device, including ultrasound echoes from the standoff layer, are processed to determine a deformation of the standoff layer caused by an axial force or pressure exerted by the ultrasound device. the deformation of the standoff layer is used, along with characteristics of the standoff layer, to generate the ultrasound device interaction indicator. in another aspect, one or more characteristics () of the acoustically translucent standoff layer () and the ultrasound signal () are processed to determine a measure of strain hysteresis of the acoustically translucent standoff layer; and, in response to a determination that the measure of strain hysteresis exceeds a predetermined hysteresis threshold, an indication is generated that the acoustically translucent standoff layer needs replacing.
