Abstract—The development of ultrasound technology allows us to see the structure and development of the fetus directly. Crown-Rump Length (CRL) and mean diameter of gestational sac (MSD) can be used to determine the age of the fetus. Both parameters are useful for measuring different aspects of the first trimester of pregnancy. This study proposes a method to obtain those parameter values automatically by converting the number pixels of ultrasound image into measurement unit. Image processing method is used to separate fetal object and gestational sac from other objects based on their boundaries. On this primary study, successive calculation of CRL and MSD using the proposed method is 60% and 70% respectively by 10 sample ultrasound images. Future expectations, these basic and other findings can be better developed to help midwives and general practitioners using ultrasound easier.
