Abstract
A method and an apparatus for displaying an ultrasound image comprising a region of interest (ROI) having an optimal image quality and a background region having a normal image quality. In the displayed image the background region lies outside the ROI. The optimal image quality within the ROI is achieved by using a set of imaging parameters which are different than the set of imaging parameters used to acquire the background image, including one or more of the following: different (e.g., shorter) transmit waveforms, an increased number of transmit focal zones per unit depth, different transmit and/or receive apertures, different center frequencies for the receive bandpass filter (primary and/or (sub)harmonics), and higher vector density (i.e., decreased vector spacing). Since the optimal imaging is restricted to a ROI, a high frame rate is still possible within the ROI depending on its size.
