• Current approaches often involve the use of multiple transducer elements during transmission to enhance the depth of penetration and Signal to Noise Ratio (SNR) where these methods typically excite multiple elements simultaneously, resulting in an unfocused ultrasound beam.
• Hence, there is need for imaging techniques with  improved frame rate and lateral resolution of images thereby providing better image quality without increasing the complexity and cost of the imaging system

The invention discloses a method of ultrasound imaging comprising the steps :

• Exciting a Set of Limited Number of Active Transmit Elements
• Inducing Diverging Waves
• Receiving Backscattered Echoes upon ultrasound
• Translating Electronically the Active Transmit Elements
• Reconstructing the Received Echoes in a Receive Beamformer
• Processing to Form an Image by converting the time-delayed echoes into pixel values
• Displaying the Image

1. The said translating step may have an overlap between two adjacent sets of active transmit elements
2. Also, the received echoes data may be from only a partial receive aperture

• Said array  formed may be a single array or two dimensional array.
• The diverging beam synthetic aperture ultrasound beamforming method offers a less complex ultrasound system by activating only 8 or 16 transducer elements during transmission
