Abstract: An actual shape estimation method for a flexible ultrasound device and to an ultrasound imaging system includes an actual shape estimation module. The module, when executed, performs the steps of the method, including determining a series of shape metrics based on a predetermined series of assumed shapes of the flexible ultrasound device, and selecting an optimal shape metric, corresponding with the smallest or largest shape metric—depending on how the shape metric is defined, of the determined series of shape metrics, wherein the assumed shape of the predetermined series of assumed shapes of the flexible ultrasound device corresponding to the optimal shape metric provides an estimation of the actual shape of the flexible ultrasound device.
