Abstract

The present invention related to a method for estimating an actual shape of a flexible ultrasound device, wherein the flexible ultrasound device comprises a flexible supporting platform and a plurality of transducer elements disposed in an array configuration on the flexible supporting platform, the method comprising: transmitting, using a first portion of the plurality of transducer elements and based on an assumed shape of the flexible ultrasound device, a focussed ultrasound beam having a predetermined transmit focus position; receiving, using a second portion of the plurality of transducer elements, an echo signal responsive to the transmitted focussed ultrasound beam, wherein each transducer element of the second portion of the plurality of transducer elements is electronically connected to a respective receive channel; calculating, based on the received echo signal, a signal phase coherence image across the receive channels; and estimating, by calculating a spatial offset in the signal phase coherence image between the predetermined transmit focus position and an observed minimum phase coherence location, the actual shape of the flexible ultrasound device
