Abstract
This paper describes a novel medical instrument that produces an image of blood flow in the capillaries under the skin surface. A laser beam is used to detect blood cell motion from the Doppler broadening of the laser light scattered from the skin. The image is generated by scanning the laser beam in a raster. The design of a practical clinical instrument is outlined and some preliminary results are presented.
摘要
本文描述了一种新型医疗仪器，它能生成皮肤表面下毛细血管中血流的图像。利用激光束通过从皮肤散射的激光的多普勒展宽来检测血细胞运动。通过在光栅中扫描激光束来生成图像。概述了一种实用临床仪器的设计并给出了一些初步结果。
