Circular arc wide beam transmission method and apparatus for ultrasonic imaging

Image Number 3 for United States Patent #8001843.

A circular arc wide beam transmission method includes setting parameters for a focusing circular arc and calculating a transmission delay for each of the array elements in a transmission aperture of a probe based on the parameters for the focusing circular arc. An ultrasonic imaging system controls each array element to transmit ultrasonic waves according to the transmission delay for that array element.
