Real-time delay-multiply-and-sum beamforming with coherence factor for in vivo clinical photoacoustic imaging of humans [PDF]

, 2019
In the clinical photoacoustic (PA) imaging, ultrasound (US) array transducers are typically used to provide B-mode images in real-time. To form a B-mode image, delay-and-sum (DAS) beamforming algorithm is the most commonly used algorithm because of its ...

Real-Time Volumetric Ultrasound Imaging for Handheld Applications [PDF]

, 2012
Medical ultrasound has many benefits over other imaging modalities, including lack of ionizing radiation, relative portability and low cost. However, the majority of ultrasound scanners image only a 2D plane of tissue, which moves with the probe. This arrangement, along with the remote display screen, requires a high level of skill and experience to ...
