Abstract:
A digital scan conversion method in an ultrasonic system having a probe, the digital scan conversion method comprising the step of:interpolating sampled data obtained from two sampling points which are positioned on two scan lines neighboring at least one pixel point and have the same radius as that of the at least one pixel point, in order to obtain pixel data corresponding to the at least one pixel point, wherein said interpolating step further comprises the steps of:(a) determining the radius and angle representing the at least one pixel point positioned between the two scan lines neighboring the at least one pixel point;(b) obtaining the sampled data from the sampling points on the two neighboring scan lines corresponding to the at least one pixel point determined in step (a); and(c) calculating the pixel data with respect to the at least one pixel point using an interpolation coefficient represented by a ratio of angles between the at least one pixel point determined in step (a) and the corresponding sampling points and the corresponding sampled data obtained in step (b).
