Spina bifda is a birth defect caused by incomplete closing around the spinal cord. Spina bifda is
diagnosed in a number of diferent ways. One approach involves searching for a deformity in the spinal
axis via ultrasound. Although easy to apply, this approach requires a highly trained clinician to locate
the abnormality due to the noise and distortion present in prenatal ultrasound images. Accordingly,
visual examination of ultrasound images may be error prone and subjective. A computerized support
system that would automatically detect the location of the spinal deformity may be helpful to the
clinician in the diagnostic process. Such a software system frst and foremost would require an
algorithm for the identifcation of the entire (healthy or unhealthy) spine in the ultrasound image. This
paper introduces a novel focking dynamics based approach for reducing the size of the search space in
the spine identifcation problem. Proposed approach accepts bone-like blobs on the ultrasound images
as bird focks and combine them into bone groups by calculating the migration path of each fock.
Presented results reveal that the method is able to locate correct bones to be grouped together and
reduce search space (i.e. number of bones) up to 68%
