Now ge has developed an additive system to print the transducer .
现在通用公司已开发出一种添加系统用于打印传感器。
The transducer is a small hand-held device that resembles a microphone , attached to the scanner by a cord .
该传感器是一种小型手持设备,像一个麦克风,通过连接线连接到一个扫描仪。
Ultrasound scanners consist of a console containing a computer and electronics , a video display screen and a transducer that is used to scan the body and blood vessels .
The image is created based on the amplitude ( strength ) , frequency and time it takes for the sound signal to return from the patient to the transducer and the type of body structure the sound travels through .
该图像是基于振幅(强度),频率和声音信号需要从病人返回到传感器的时间和身体结构类型所创建。
The company will not disclose precisely how it managed to engineer an ultrasound transducer down to such a small scale , but fitting one into the tip of a catheter allows measurements to be taken accurately enough for surgeons to monitor the build up of scar tissue in real time .
