Abstract
Disclosed is an ultrasound probe that includes an array of CMUT (capacitive micromachined ultrasound transducer) cells. Each cell includes a substrate carrying a first electrode of an electrode arrangement. The substrate is spatially separated from a flexible membrane by a gap. The flexible membrane includes a second electrode of the electrode arrangement. The ultrasound probe also includes an acoustic window over the array of CMUT cells. The ultrasound probe further includes a data storage element accessible to an external control module of the ultrasound probe. The data storage element stores configuration information for configuring an operation of the array of CMUT cells in pre-collapse or collapse mode with the external control module to optimize the effective bandwidth of the array. Also disclosed is a calibration method of the ultrasound probe, an ultrasound system and a method of operating the ultrasound system.
