摘要：
Disclosed is an ultrasound probe (10) including an array (110) of CMUT (capacitive micromachined ultrasound transducer) cells (100), each cell comprising a substrate (112) carrying a first electrode (122) of an electrode arrangement, the substrate being spatially separated from a flexible membrane (114) including a second electrode (120) of said electrode arrangement by a gap (118)； an acoustic window (140) over the array of CMUT cells； and a data storage element (150) 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.
