Abstract:
This paper introduces the generating principle of energy correction table for digital gamma camera and elaborates a method for real-time energy correction. According to the position information of the collected events, correction cells are determined. With the correction value in four adjacent correction cells, coefficient of energy correction is worked out through bilinear interpolation. Finally, real-time energy correction for the collected events is achieved through software programming.
