Abstract
Ultrasound (US) imaging is scaled to arrays having a large number of elements. We use 'active windows' to define the parts of the overall array that are active for transmission and reception. Each active window is 2D. Local electronics can move these active windows freely within the array, either together or independently. This effectively provides fast scanning by electronically moving the active windows around within a large stationary array. All of the elements within an active window are individually controlled for beam forming, focusing etc. by beam forming electronics in the system controller. Thus there is no need to have all of the elements of the large, stationary 2D ultrasound array connected to the system controller.
