CT系统参数标定及成像和CT技术图像重建(CT technology, image reconstruction)

CT系统安装时往往存在误差，从而影响成像质量，因此需要对安装好的CT系统进行参数标定，即借助于已知结构的样品（称为模板）标定CT系统的参数，并据此对未知结构的样品进行成像。(CT system installation errors often occur, thus affecting the image quality, therefore need calibration of CT system installed parameters, which is based on the kn

可以利用接受信息和模板几何信息对ct进行参数标定(The CT can be calibrated by using the received information and template geometry information)
