Abstract:

An interactive apparatus which includes (a) a processing unit automatically implementing a cardiac treatment algorithm, by using detected signals from a patient and the cardiac treatment algorithm, to output a recommended treatment on an output device; and (b) an input device inputting a selection comprising an acceptance or a rejection of the recommended treatment, wherein if the selection comprises an acceptance, then the processing unit outputs instructions and further implements the treatment algorithm using the recommended treatment, wherein if the selection comprises a rejection, then the processing unit outputs an alternative recommended treatment on the output device, subject to acceptance or rejection by the input device.

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.
