研究了弹性成像技术在体外生物软组织热损伤可视化中的应用。用外科手术用的Nd：YAG激光在死后的绵羊肾脏标本上造成热损伤。肾脏样本在凝胶中浇注，使用超声信息和外部标记构建病变的弹性图像，以定位感兴趣区域。肾脏样本的肉眼病理证实了病变的大小。根据弹性成像图像和大体病理照片，发现沿激光纤维轴的病变长度与从纤维轴测量的最大直径之间有很好的相关性。(C)1998年世界医学和生物学超声联合会。
The use of elastography for the visualization of thermal lesions in biological soft tissue in vitro was investigated. Thermal lesions were created in samples of postmortem ovine kidney using a surgical neodymium: YAG (Nd:YAG) laser. The kidney samples were cast in gel, and elastographic images of the lesions were constructed using sonographic information and external markers to locate the region of interest. Gross pathology of the kidney samples confirmed the dimensions of the lesions. Good correlation between the lesion length along the laser fiber axis and maximum diameter measured off of the fiber axis determined from elastographic images and gross pathology photographs was found.
