ultrasonic diagnostic imaging principle

probe transmit ultrasonic waves to human body → ultrasonic wave is reflected, scattered，refracted in human body → express shape structure of organs, distribution of vessels and blood flow index with waveform, images, sounds, spectrum etc.

超声波诊断仪成像原理：探头向人体内发射超声波 → 超声波在人体内发生反射、散射、折射 → 探头接收人体内反射和散射回来的超声波 → 最后以波形、图像、声音、频谱等来表达脏器形态结构或血管的分布情况及血流动力学指标
