Abstract:
1. A method for controlling contrast agent medical diagnostic ultrasound imaging, the method comprising: acquiring ultrasound frames of data representing, at least in part, information from contrast agents, the ultrasound frames representing a region of a patient at different times; comparing at least two of the ultrasound frames from the different times, the comparing indicating a scalar value of a difference between same locations of the region represented in the at least two of the ultrasound frames; altering a number of scan lines per second for subsequently acquired ultrasound frames of data representing the contrast agents, the altering being based on the scalar value of as a function of the difference, wherein altering results in decreasing the number from a first value for an arterial phase to a second value for a portal phase and from the second value to a third value for a late phase, the portal phase being after an arterial phase and before the late phase; and generating an image from at least one of the subsequently acquired ultrasound frames.
