Abstract
An imaging system incorporating the invention includes a transducer for scanning an imaging beam through a region of interest (ROI) which includes a structure or function to be imaged on a display, such as an anatomical structure or a hemodynamic function. A processor is responsive to a changes in the image that are caused by changes in imaging beam position, to calculate at least a first measure of a feature of the structure or function and to cause the display to manifest the first measure by a first indication. The processor may also be responsive to a further change in the image brought about by movement of the imaging beam, to calculate at least a second measure of the feature and to cause the display to manifest the second measure by a second indication. The user is thereby able to determine by display of the first and second indications, of the relative difference in positions of the transducer. The processor also determines from a plurality of scans of the imaging beam, an extreme (or target) one of plural ones of the first measure and causes the first indication to manifest the extreme (or target) one of the plural ones of the first measure. Such display enables a user to know how much to reposition the imaging beam so as to assure that the first measure is at the extreme or target value.
