Beschreibung
Zusammenfassung:	An ultrasound system (100) for imaging a volumetric region comprising a region of interest (12) comprising: a probe having an array of CMUT transducers (14) adapted to transmit ultrasound beams and receive returning echo signals over the volumetric region; a beamformer (64) coupled to the array and adapted to control ultrasound beam transmission and provide ultrasound image data of the volumetric region; a transducer controller (62) coupled to the beamformer and adapted to vary driving pulse characteristics of the CMUT transducers, a region of interest identifier (72) enabling an identification of a region of interest on the basis of the ultrasound image data; a beam path analyzer (70) responsive to the ROI identification and arranged to detect an attenuating tissue type in between the probe and the ROI based on a depth variation in attenuation of the received signal; wherein the transducer controller is further adapted to change, based on the attenuating tissue type detection, at least one parameter of the driving pulse characteristics.
