Abstract (in Japanese) (See Japanese page) 
(in English) Functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET) are often used for imaging particularly active brain locations. However, spatial resolution of these devices is at most 0.5mm and thus is not sufficient to investigate blood flow changes at micro-vascular level. In this study, we use the small implantable CMOS imaging device developed by our research group. The conventional methods for determining blood flow velocity have had limitations with inevitable variations arising due to manual measurement. In the experiment, the blood flow velocity was estimated by focusing on the movement of red blood cells in the videos. Our proposed method applies correlation and automatically determines the blood flow velocity without physical inspection.
