As an alternative to delay-and-sum beamforming, a novel beamforming technique called filtered-delay multiply and sum (FDMAS) was introduced recently to improve ultrasound B-mode image quality. Although a considerable amount of work has been performed to evaluate FDMAS performance, no study has ...
Recently a new beamformer called the Delay-Multiply-And-Sum (DMAS) beamformer was introduced in the field of medical ultrasound imaging (Matrone et al IEEE Trans. Med. Imag. 2015). Instead of summing the signals recorded by each transducer element as with the Delay-And-Sum (DAS) beamforme...
Light-emitting diode-based photoacoustic imaging is more compact and affordable than laser-based systems, but it has low power and hence a high number of replicates. Here, we describe double-stage delay-multiply-and-sum (DS-DMAS) to improve image quality collected on a LED-based scanner. DS...

(VNA) recorded backscattered signals from the artificial breast phantom with and without tumors at various positions and times. Delay and sum (DAS) and Delay multiply and sum (DMAS) beamforming algorithms processed S-parameters. MATLAB digitizes these signals to detect breast cancer. DMAS detects ...
RF > 1 requires time or phase delay and attenuation control to accomplish RF beamforming. The assumption here is a time delay unit and a variable attenuator sit between two gain stages. The extra gain stage vs. the RF = 1 case doubles the DC power and is required to overcome the TDU ...
Time-domain beamformers using delay lines to form simultaneous multiple beams have the disadvantage that they require many output taps per delay line, since a summation across the delay lines is needed for each beam output. This makes such devices difficult and expensive to build because many int...
