An ultrasound system with a tissue type analyzer

An ultrasound system for imaging a volumetric region comprising a region of interest comprising:

• an array of CMUT transducers adapted to transmit ultrasound beams and receive returning echo signals over the volumetric region;
• a beamformer coupled to the array and adapted to control ultrasound beam transmission and provide ultrasound image data of the volumetric region;
• a transducer controller coupled to the beamformer and adapted to vary driving pulse characteristics of the CMUT transducers,
• a region of interest identifier enabling an identification of the region of interest on the basis of the ultrasound image data, and which identifier is adapted to generate identification data indicating the region of interest within the volumetric region;
• a beam path analyzer responsive to the identification data and coupled to the beamformer, said beam path analyzer arranged to detect an attenuating tissue type in between the array and the ROI based on a depth variation in attenuation of the received signal;
• wherein
• the transducer controller is further adapted to adjust, based on the attenuating tissue type detection, at least one parameter of the driving pulse characteristics.
