Abstract
Images of the heart are formed by using multiple sets of ultrasound data. Each set of data is acquired and processed responsive to a different set of imaging parameters. The imaging parameter sets differ in at least one parameter, such as array position, temporal frequency response or transmit focal depth, so that the images formed using these data sets have, either laterally or axially, different spatial spectra. A set of images is formed responsive to a first imaging parameter set for a first cardiac cycle. Another set of images is formed responsive to a second imaging parameter set for a second cardiac cycle. The two sets of images are temporally aligned so that they correspond to the same set of phases of the cardiac cycle. Since the data acquisition and processing are distributed over multiple cycles of the motion, assuming regular periodic heart cycle, temporal resolution is maintained.
