呼吸效应的近似模型是，受询问的胸部区域的横截面经历时变放大和沿两个垂直轴的位移——我们建议将此运动建模为参数仿射运动。描述了基于投影域中的正弦图数据来确定仿射运动参数的理论框架，该仿射运动对全局呼吸运动进行建模。假设所考虑的空间图像是质量守恒成立的密度图像。
An approximate model for the effect of respiration is that the cross section of the thoracic area under interrogation experience time-varying magnification and displacement along two perpendicular axes — we propose to model this motion as parametric affine motion. A theoretical framework for determination of parameters of affine motion modeling the global respiratory motion based on the sinogram data in the projection domain is described. It is assumed that the spatial image considered is a density image where conservation of mass holds.
