本文介绍用多个接收单元放在不同角度的位置上同时接收来自发射探头的声脉冲,并用电子顺序扫描将信号幅度显示在屏幕上,即可得到一个脉冲超声场指向性的实时图形。本文对该方法和仪器作了介绍和讨论。
This article describes the use of multiple receiving units placed at different angles on the same time receiving the sound from the transmitting probe pulse and electronic sequential scanning of the signal amplitude displayed on the screen to get a pulsed ultrasound field directivity real-time graphics. This article describes and discusses the method and instrument.
