【摘要】：成像技术已经在心血管疾病的诊断、治疗计划的制定和指导介入治疗等方面得到广泛应用。呼吸运动是指通过胸廓有节律地扩大和缩小来完成吸气和呼气,会引起心脏在三维空间中的整体平移,严重影响心脏图像的获取和图像质量。利用自由呼吸条件下采集的图像对呼吸运动进行建模,并对其进行抑制和补偿,成为解决这一问题的主要方法。本文在介绍呼吸运动对心脏成像影响的基础上,归纳呼吸运动抑制和补偿的方法,并着重介绍呼吸运动建模的方法。
[Abstract]:Imaging technology has been widely used in the diagnosis of cardiovascular disease, the formulation of treatment plan and the guidance of interventional therapy. Respiratory movement is defined as the rhythmic expansion and contraction of the chest to complete the inspiratory and exhalation, which will cause the heart to move in the three-dimensional space, and seriously affect the acquisition and image quality of the heart image. The main method to solve this problem is to model, suppress and compensate the breathing motion by using the images collected under the condition of free breathing. Based on the introduction of the effects of respiratory motion on cardiac imaging, the methods of respiratory motion inhibition and compensation are summarized, and the modeling method of respiratory motion is emphasized.
