Since the first comprehensive computerized videometric systems for quantitative assessment of the dynamic morphology and function of the heart have been developed, angiocardiographic image generation and computer aided evaluation have improved considerably. As a second method for morphological imaging echocardiography is also established in cardiology, so that videometry branched off into angio- and echocardiometry. In this paper, the common aspects of both methods are discussed concerning manual outlining and computerized contour representation, additional storage of anatomical landmarks labelled by digits and letters, and list-directed automated evaluation of data. It allows standard graphical documentations including comparisons of global volumetric and functional results for individual patients as well as versatile research orientated evaluations of oblique semi-axes, sectorial areas, wall thicknesses, shape parameters, spatial orientation and derived global and regional functional parameters for patient groups. As an example wall thickness measured from echographic long and short axis views and from angiographic projections are compared.
自从首个用于心脏动态形态和功能定量评估的综合计算机化视频测量系统开发以来，心血管造影图像生成和计算机辅助评估有了显著改进。作为形态学成像的第二种方法，超声心动图在心脏病学中也已确立，因此视频测量分支为血管造影测量和超声心动图测量。本文讨论了这两种方法在手动勾勒轮廓和计算机化轮廓表示、以数字和字母标记的解剖标志的额外存储以及数据的列表导向自动评估方面的共同之处。它允许进行标准的图形记录，包括对个体患者的整体容积和功能结果进行比较，以及对患者组的斜半轴、扇形面积、壁厚、形状参数、空间方向以及导出的整体和区域功能参数进行多用途的研究导向评估。例如，比较了从超声心动图长轴和短轴视图以及血管造影投影测量的壁厚。
