(ZH) 建立血管截面函数、血管压力差和血管应力的方法及装置
Abstract
(EN)
The invention relates to a method and device for building a blood vessel section function, a blood vessel pressure difference and blood vessel stress. The method for building the blood vessel sectionfunction comprises the following steps of obtaining image data including at least one cardiac cycle; within one cardiac cycle, selecting a plurality of characteristic moments; according to the image data, generating a space model of a target region blood vessel corresponding to each characteristic moment; according to each space model, in the axial direction of the target region blood vessel, building a first section model at each position of the target region blood vessel; according to each first section model, building a corresponding first section function. Compared with the prior art, themethod can more precisely reflect the actual blood vessel condition, an intermediate variable with a small error is provided for follow-up analysis operation, and a later calculation value is closer to an actual value.

本发明涉及一种建立血管截面函数、血管压力差和血管应力的方法及装置。其中,建立血管截面函数的方法包括以下步骤:获取包含至少一个心动周期内的影像数据;在一个心动周期内,选取若干个特征时刻;根据影像数据,生成与每一特征时刻相对应的目标区域血管的空间模型;根据每一空间模型,沿目标区域血管的轴向方向,建立目标区域血管的各个位置处的第一截面模型;根据每一第一截面模型,建立相应的第一截面函数。该方法相较于现有技术,能够更为精准地反映出实际血管情况,为之后的分析运算提供了一个误差较小的中间变量,以使后期的计算值更靠近实际值。
