为了解决获取准确的脉冲能量信息所需的高采样率与需要及时处理的大量数据之间的矛盾，前端读出系统通常采用一种算法来校正由于降低采样率而引起的误差，这有助于从数字化的脉冲波形中提取准确的能量信息。对不同拟合次数的多项式拟合、不同采样模式下的双指数函数拟合、积分面积法等算法的功能和效果进行了分析和评价，并给出了一些有意义的结果。该算法已在重离子治癌装置正电子发射断层扫描（PET）原型系统中得到初步应用。
In order to solve the contradiction between requirements of high sampling rate for acquiring accurate energy information of pulses and large amount of data to be processed timely, the method with an algorithm to correct errors caused by reducing the sampling rate is normally used in front-end read-out system, which is conductive to extract accurate energy information from digitized waveform of pulse. The functions and effects of algorithms, which mainly include polynomial fitting with different fitting times, double exponential function fitting under different sampling modes, and integral area algorithm, are analyzed and evaluated, and some meaningful results is presented in this paper. The algorithm described in the paper has been used preliminarily in a prototype system of Positron Emission Tomography (PET) for heavy-ion cancer therapy facility.
