Abstract
A region of interest in the body is imaged using at least two different trigger intervals between images. Imaging automatically switches from one trigger interval to another in response to a user command, such as depressing a button. This automation avoids cumbersome manual changes of the trigger intervals. Perfusion is measured in a shorter time in this way, reducing the effects of breathing and transducer movement. Variation of the trigger intervals allows for a convenient determination of perfusion. For example, the trigger intervals are varied from one heart cycle to two heart cycles and then to other integer numbers of heart cycles.
