...Most recently, a method named Filtered Delay weight Multiply and Sum (F-DwMAS) beamforming was proposed, which utilized an optimal weighting strategy for F-DMAS to improve the reconstructed image quality for the data acquired using 2-element Receive Synthetic Aperture Focusing Technique (2R-SAFT) scheme [27]....

...A new beamforming method called as Delay Multiply and Sum beamforming (DMAS) proposed in the microwave literature was recently adapted to the US imaging with some modifications and was named as Filtered Delay Multiply and Sum beamforming (F-DMAS) [6]....

...Also, the developed method was used to reconstruct the data acquired using 2R-SAFT, instead of conventional focused beamforming or plane wave imaging or Synthetic Transmit Aperture (STA) where the use of FDMAS has been reported [6,9,10]....

...Due to the multiplication of the signals with similar frequency content a DC and a second harmonic component appears in the spectrum of DMAS, therefore a further step of bandpass filtering was introduced to filter the DC and higher frequency components and is named as filtered DMAS (F-DMAS)[6]....
