英国伦敦血管研制机构正在研制一种微型血管探测器,用以拍摄血管内部图像,为心血管手术提供有力的工具。该探测器的导管内设有十四条信号传输线,将超声波探测数据传回人体外部的计算机中,计算机根据这些数据绘制出血管内部的图像。 British vascular development agencies are developing a micro-vascular detector to capture images of the internal blood vessels, cardiovascular surgery provides a powerful tool. There are fourteen signal transmission lines in the catheter of the detector, and the ultrasonic sounding data is transmitted back to the computer outside the human body. The computer draws the internal image of the blood vessel based on the data.
