Реферат: The invention provides a method of imaging the heart. An ultrasound probe is controlled to receive first reflected ultrasound echo signals from the heart transmitted using first transmit parameters and an ultrasound image of the heart is created from the first reflected ultrasound echo signals using first echo signal processing parameters. Model-based segmentation is performed of the ultrasound image to identify anatomical structures of the heart, and, for at least one anatomical structure which has areas of dropout, the segmentation is used to extrapolate from the identified anatomical structures to identify the location within the image of the areas of dropout. A next ultrasound image of the heart is obtained using second, different, echo signal processing parameters and/or second, different, transmit parameters specifically for the at least one anatomical structure, or for the areas of dropout for the at least one anatomical structure, thereby to improve the signal to noise ratio at least for the areas of dropout.
