Implementation of image segmentation on foetus ultrasound imaging system

Obstetrics ultrasound scan has been a vital routine for a pregnant mother to get information on the foetus dating and growth. Foetus ultrasound image is normally not clear and contains unwanted noise. Furthermore, the displayed foetus scan on the monitor screen can be not in complete stationary because of the slight movement of the held ultrasound probe. Thus, a computerized method to do segmentation on the foetus image should be implemented. To obtain precise measurements, obstetrician needs to freeze the best possible scene throughout the scanning session. With the segmentation technique implemented, the point locations for measurement can be generated without the participation of the obstetrician. In this paper, the applied segmentation technique is variational level set algorithm. Based on the segmentation results, the level set contour evolved well on the ultrasound image although it is low in contrast and contains image noise.
