The use of structured lights and especially of the Moiré technique to evaluate chest wall distortion in front of the apical impulse allows a topographic study of the precordial movement in relation with cardiac activity. Shade Moiré technology offers the possibility to study a reduced area of the chest with a good enlargement effect and well contrasted fringes. Projected Moiré allows the study of an increased area of the chest (40 cm2) and provides less contrasted pictures with a reduced enlargement effect. Both techniques offer the possibility of automatic imaging. The study of a normal subject is realized with a topographic evaluation of the chest wall distortion on a endsystolic frame. 3D representation of the chest wall deformation is performed after image treatment on a endsystolic print.
使用结构化光尤其是莫尔技术来评估心尖搏动前方的胸壁变形，能够对心前区运动与心脏活动的关系进行地形学研究。阴影莫尔技术提供了研究胸部较小区域的可能性，具有良好的放大效果和对比度高的条纹。投影莫尔技术能够研究更大的胸部区域（40平方厘米），但提供的图像对比度较低且放大效果减弱。这两种技术都具备自动成像的可能性。对正常受试者的研究是通过在收缩末期帧上对胸壁变形进行地形学评估来实现的。在收缩末期打印图像上进行图像处理后，对胸壁变形进行三维呈现。
