Data is captured for different contrast agent perfusion imaging options. For example, two different maximum intensity projection (MIP) combinations of frames are formed during scanning, one with motion correction and one without. As another example, the component frames of data are stored to allow any combination after scanning. If one combination is less desirable, then another combination may be provided without requiring further injection or additional scanning. In another embodiment, the sufficiency of combination is detected and the combination of frames is selected automatically as a function of ultrasound data.
