This study focuses on in-vivo transcranial visualization of blood flow without removing the skull. Traditional methods struggle due to skull-induced attenuation, scattering, and distortion. Our approach detects blood flow using ultrasonic speckle reflections from moving blood cells and platelets. By targeting these random temporal changes and eliminating static components, we can image the flowing region despite the skull's negative acoustic effects. Experimental results demonstrate the ability to produce accurate 2D and 3D images of blood flow, consistent with the physical size of vessel analogues and providing qualitative flow measurements.
