Color flow display with compensation for flow direction
First Claim
1. An ultrasound imaging system, comprising:
- display means for displaying an ultrasound image;
transducer means for transmitting an ultrasound beam which is steerable between positive and negative transmission angles, about an intermediate azimuth extending orthogonally from an emitting face of said transducer means;
user input means for providing steering signals to cause said transducer means to alter a direction angle of transmission of said ultrasound beam;
processor means for controlling said display means to display an image of fluid flowing in a direction towards said transducer means with a first attribute and an image of fluid flowing in a direction away from said transducer means with a second attribute, said processor means responsive to a steering signal which causes said ultrasound beam to be moved from one side of said intermediate azimuth to another side of said intermediate azimuth, to automatically display said image of fluid flowing in a direction towards said transducer means with said second attribute and said image of fluid flowing in a direction away from said transducer means with said first attribute.

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.
