Abstract

一种CT系统参数确定方法及装置(1，140)，涉及计算机成像技术领域，包括:控制具有互相垂直的第一平面(A1)和第二平面(B1)的模体(M)，在X射线源(01)和探测器(02)的探测面(Y)之间移动，并获取模体(M)在移动过程中在探测面(Y)上的X射线投影(301)，其中，在模体(M)移动的过程中，第一平面(A1)和第二平面(B1)始终垂直于探测面(Y)；根据获取到的X射线投影确定第一直线(Lu)和第二直线(Lv)(302)；将第一直线(Lu)与第二直线(Lv)的交点(O')确定为X射线源(01)的焦点(S)在探测面(Y)上的垂足坐标(303)，CT系统参数包括垂足坐标。方法解决了模体(M)的制造工艺较复杂的问题，简化了模体(M)的制造工艺，用于确定CT系统参数。
