Abstract:
An ultrasound imaging system, comprising:a display device; ultrasound transducers for transmitting ultrasound signals toward a target object; a storage means for storing signals received at the ultrasound transducers in response to the transmitted ultrasound signals; and a processing means for determining a receive-focused signal that is receive-focused at a selected point of the target object, the selected point corresponding to a certain pixel in the display device, wherein the ultrasound transducers transmit-focus ultrasound signals at a point on each of a plurality of scan lines, and the processing means determines characteristics of the reflected ultrasound signals received by each of the ultrasound transducers from multiple points on an imaginary scan line in response to the ultrasound signals transmitted on at least two of the plurality of scan lines, wherein the imaginary scan line includes the selected point and is between the at least two scan lines for computing display data for the selected point, and wherein the characteristics of the reflected ultrasound signals from the multiple points are weighted according to on which one of the at least two scan lines the ultrasound signals were transmit-focused.
