Abstract
The phase or associated amplitude analysis of a sequence of images is improved by, first, providing quantifications in response to the phase or amplitude information. For example, a value or values representing asynchrony between different locations through a sequence of images may provide useful diagnostic information. Second, since heart motion or other motion within a body may become complex, multiple harmonics may be used in addition to the first harmonic or fundamental information for parametrically imaging a motion. Third, where different portions of a cycle have different characteristics, such as the systolic phase and diastolic phase of a heart cycle, images associated with each of the portions may be separated from other portions. A phase or amplitude analysis of the sequence of images for each portion is handled separately.
