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 ...

Photoacoustic Tomography System [PDF]
Journal of Applied Research and Technology, 2012 Basados en el efecto fotoacústico pulsado, se desarrolló un dispositivo experimental para generar imágenesbidimensionales de muestras ópticamente opacas ocultas en un medio turbio. El medio turbio se hizo de agar ynanopartículas monodispersas, con estos materiales indujimos una absorción y esparcimiento óptico semejante al delos tejidos humanos.
