1. An ultrasound system for imaging a volumetric region comprising a region of interest, said system comprising:
a probe comprising an array;
an ultrasound wave controlling unit coupled to the array and adapted to control ultrasound wave transmission by the array and provide ultrasound image data of the volumetric region;
an image processor responsive to the ultrasound image data, based on which it is adapted to produce an ultrasound image;
a region of interest (ROI) identifier configured to identify a region of interest on the basis of the ultrasound image data, and which ROI identifier is adapted to generate identification data indicating the region of interest within the volumetric region;
a user interface;
wherein the ultrasound wave transmission within the volumetric region is configurable by a plurality of use cases in response to respective identification data of said use cases, each use case being associated with a particular imaging procedure and comprising: (i) an anatomical model for said imaging procedure; and (ii) one or more configuration parameters for the ultrasound system for said imaging procedure, and comprising guidance instructions for assisting a user of the probe in guiding the probe to a target location;
wherein the ultrasound system is configured to receive, from the user via the user interface, a particular use case identifier configured to identify a particular use case;
wherein the ultrasound system is configured to, in accordance with the particular use case identified by the particular use case identifier: (1) automatically configure the ultrasound wave transmission; (2) provide guidance instructions; and (3) provide automated ROI detection, wherein the ROI identifier is configurable by the respective anatomical models of said use cases;
wherein automatically configuring the ultrasound wave transmission comprises automatically varying, by the ultrasound wave controlling unit in accordance with the particular use case identified by the particular use case identifier, a frequency of the ultrasound waves transmitted within the ROI and the volumetric region surrounding the identified ROI;
wherein the image processor is configured to analyze, based on the particular use case identifier and the ultrasound image data, one or more image quality parameters, and wherein the ultrasound system is configured to automatically adjust, based on the analyzed one or more image quality parameters, the probe to optimize the ultrasound image data for the particular use case,
wherein the ultrasound wave controlling unit further comprises a beamformer adapted to control ultrasound beam steering of the transmitted ultrasound wave; and wherein the ultrasound beam steering is adapted to be configured by the plurality of use cases in response to the respective identification data of said use cases,
wherein the probe comprises an array of capacitive micro-machined ultrasonic transducer (CMUT) transducers adapted to steer ultrasound beams in a variable frequency range over the volumetric region; and the ultrasound system further comprises a transducer frequency controller coupled to the beamformer and adapted to vary operation frequencies of the CMUT transducers within the frequency range; which frequency controller is arranged to set the operation frequency to a first frequency for the ultrasound beam steered in the volumetric region,
wherein the transducer frequency controller is further adapted to change, based on the identification data, the operation frequency to a second frequency for the ultrasound beams steered within the region of interest, the second frequency being higher than the first frequency; and
a drive mechanism coupled to the probe, wherein the drive mechanism is adapted to move the probe, based on the identification data, enabling a distance variation between the probe and the ROI.
