Efficient nonlinear beamformer based on P’th root of detected signals for linear-array photoacoustic tomography : application to sentinel lymph node imaging
In linear-array transducer-based photoacoustic (PA) imaging, B-scan PA images are formed using the raw channel PA signals. Delay-and-sum (DAS) is the most prevalent algorithm due to its simple implementation, but it leads to low-quality images. Delay-multiply-and-sum (DMAS) provides a higher image q...
