Abstract
An ultrasound imaging system includes a display for displaying an ultrasound image and a transducer for transmitting a linear ultrasound beam which is steerable between positive and negative beam angles about an intermediate azimuth which extends from an emitting face of the transducer. A user input control provides steering signals to cause the transducer to alter the direction angle of transmission of the ultrasound beam. A processor controls the display to produce an image evidencing a first attribute of fluid flowing in a direction towards the transducer and an image with a second attribute of fluid flowing in a direction away from the transducer. The processor is responsive to a steering signal which causes the ultrasound beam to move from one side to the other side of the intermediate azimuth to display the image of fluid flowing in a direction towards the transducer with the second attribute and the image of fluid flowing in a direction away from the transducer with the first attribute. Similarly, the attributes, as displayed by a color bar, are reversed at the same time to be in accordance with the changed blood flow coloration.
