Automatic Gestational Age Estimation by Femur Length Using Integral Projection from Fetal Ultrasonography

摘要

The accuracy of scanning is important to properly know a fetus condition in the womb. However, the results still depend on a doctor's observation, so there are possibility of errors in identification. We propose an automatic gestational age identification system of images Using femur length parameters to reduce identification errors. The method used is a combination of Gaussian Filter, Morphology Operation, and Canny Edge Detection methods to improve scanning result and to minimalize the noise. Find Contour method is used to obtain the fetal femur object, then searched for femur length Using Integral Projection. This study uses samples of fetal femur data in second trimester. From the result of the study Integral Projection can be used to measure the femur length with an average success rate of 94.8% and the identification of gestational age with an average success rate of 97.6%.
