Visualization of pulsation Amplitude in B-mode Cranial Ultrasound Images

Cranial ultrasound scans are very essential part of the routine investigation of neonatal intensive care. The scan ultrasound image sequence are not only used for real-time diagnosis but also recorded for future diagnosis, offline analysis of ultrasonogram images and the study of tissue velocity in neonatal cranium. Tissue motion in neonatal cranium is an important physical parameter in discussing the pulsation strength of newborn baby for paediatric diagnosis. In this paper, we analyze and visualize the neonatal brain tissue motion caused by artery pulsation of blood flows from a video stream of ultrasound image sequence by using 1D fast Fourier transform in brightness mode for future diagnosis. The analysis has the advantages of observing pulsation amplitude of pulsatile tissues in different coronal and sagittal sections which may strongly contribute paediatricians in diagnosis of newborn baby's ischemic diseases. In our method, we analyze and visualize the tissue motion of different coronal and sagittal sections of normal and asphyxiated neonates.
