抄録
A Hi-8 moving-image processing system with low noise and high spatial resolution is constructed by using a Hi-8 video cassette recorder with frame memory and a IBM-PC computer installed with a frame grabber board. Subsequently, a program to detect artery pulsation from a series of ultrasoundecho moving images of a newborn baby's head is developed, based on the discrete Fourier transform of the time-sequence variation of pixel value. It is then demonstrated that a weak artery pulsation is successfully detected, besides anterior, posterior, middle cerebral artery, anterior choroidal artery, circle of Willis, and basilar artery pulsations.
