  • Publication number: 20200164405
    Abstract: An ultrasound system has a set of CMUT transducer devices and drive electronics for operating a selected device of the set. The drive electronics is shared between all devices of the set. Selection is made by using a set of switches (178), with a respective switch between a DC bias output (166) of the drive electronics and an associated input (160) of each device. This provides a simple way to provide a selection function between the drive electronics and multiple ultrasound devices. In this way, the number of devices may be scale up, to cover a larger area, but without scaling the cost of the system by the same degree.
