一、前言国外在五十年代就开始进行超声三维显象的研究了。这是因为临床诊断医师要想从若干个断层(二维)图象了解心室或其它脏器的形状及邻近空间的关系,在很大程度上取决于实际的工作经验。诊断人员必须根据许多断层图象(尽管所得信息有限)来准确判断病变部位的形状。如果对人体结构(特别是内脏器官结构)不太熟悉的话,诊断效果就很差,并且还费时。因此,长期以来,医师们一直希望有一种能客观地显示人体内部脏器的三维图象的方法。而从事超声研究 I. Foreword Abroad in the fifties began to study ultrasound three-dimensional imaging. This is because the clinician’s physician who wants to know the shape of the ventricle or other organs and the relationship between adjacent spaces from several tomographic images depends largely on the actual working experience. The diagnostician must accurately determine the shape of the lesion on the basis of many tomographic images, despite the limited information available. If not familiar with the human body structure (especially the visceral organ structure), the diagnostic effect is poor, and also time-consuming. Therefore, for a long time, physicians have long wanted a way to objectively display three-dimensional images of internal organs of the human body. And engaged in ultrasound research
