Abstract
A method and ultrasonic diagnostic imaging system for contrast agent imaging or tissue harmonic imaging is described which modulates the transmit power as a function of the angle of an electronically steered beam or the location of the beam in the scan plane to compensate for the reduction in delivered energy to points in the image field resulting from off-angle steering or a reduction in the number of elements of the transmit aperture.
