Abstract
An ultrasound system () is disclosed that comprises a probe () including an array () of CMUT (capacitive micromachined ultrasound transducer) cells (), each cell comprising a substrate () carrying a first electrode (), the substrate being spatially separated from a flexible membrane () including a second electrode () by a gap (); and a bias voltage source () coupled to said probe and adapted to provide the respective first electrodes and second electrodes of at least some of the CMUT cells with a monotonically varying bias voltage including a monotonically varying frequency modulation in a transmission mode of said probe such that the CMUT cells are operated in a collapsed state and transmit at least one chirped pulse during said transmission mode. Such a system for instance may be an ultrasound imaging system or an ultrasound therapeutic system. An ultrasonic pulse generation method using such as system is also disclosed.
