Systems and methods for adaptive volume imaging
Systems and methods which provide volume imaging by implementing survey and target imaging modes are shown. According to embodiments, a survey imaging mode is implemented to provide a volume image of a relatively large survey area. A target of interest is preferably identified within the survey area for use in a target imaging mode. Embodiments implement a target imaging mode to provide a volume image of a relatively small target area corresponding to the identified target of interest. The target imaging mode preferably adapts the beamforming, volume field of view, and/or other signal and image processing algorithms to the target area. In operation according to embodiments, the target imaging mode provides a volume image of a target area with improved volume rate and image quality.
1. An ultrasound imaging system comprising:
an ultrasound transducer;
a processor operable under control of an instruction set to generate images using information acquired by the ultrasound transducer, wherein the processor is configured to
generate a survey image from a survey volume image data set;
receive an indication of an item of interest in the survey image;
adjust one or more imaging parameters based on the indicated item of interest; and
generate a target image from a target volume image data set that is obtained with the one or more adjusted imaging parameters,
wherein the one or more adjusted imaging parameters cause the target image to cover only the indicated item of interest.
