Interpolation of CT Images for Three Dimensional Display

In this paper three methods are used to interpolate the CT image data in the axial direction for three dimensional display of them. The methods used here are (1) polynomial interpolation, (2) a method based on geometrical mean or mean square and (3) a method using partial cross-correlation function. From the results of computer simulation, it is concluded the method using partial crosscorrelation function gives good results though the processing needs much computer time. Some results on CT images are also presented.
