Abstract: A method for modeling an internal object of a human body includes the step of obtaining the original three-dimensional volume data of the internal object of a human body utilizing an ultrasonic imaging device. Thereafter, a desired area of the obtained original three-dimensional volume data is selected and the image quality of the desired area is enhanced. The desired area of the three-dimensional volume data is transformed into a fair shape data. The fair shape data is decimated while a modeled shape is maintained. Finally, a three-dimensional model is shaped using decimated shape data.
