用扫描激光声学显微镜获得的皮肤伤口组织和周围边缘的超声表征的初步结果显示，随着伤口年龄的变化，声速和声学异质性增加。随着伤口年龄的增长，观察到以下结果：（1）伤口区域的声学外观从最初的均匀性逐渐变得不均匀：（2）伤口的声学外观趋向于变得与邻近组织的声学外观相似;（3）伤区超声速度由伤后7天的1540--1575 m/s增加到伤后35天的1700--2000 m/s。
Preliminary results of the ultrasonic characterization of cutaneous wound tissue and surrounding margin, obtained with the scanning laser acoustic microscope, show an increase in the speed of sound and in the acoustic heterogeneity as function of wound age. As the wound age increased, the following results were noted: (1) The wound area, initially quite homogeneous in acoustic appearance, became more heterogeneous; (2) the acoustic appearance of the wound tended to become similar to that of the adjacent tissue; and (3) the ultrasonic velocity of the wound area increased from a range of 1540--1575 m/s at 7 days to a range of 1700--2000 m/s at 35 days.
