随着医学技术的快速发展,具备加彩、变频功能的医用超声诊断仪已广泛应用于各级医疗机构,用于进行临床诊断和对孕妇胎儿的检查工作。仪器本身的一些设置会对测量结果产生影响,但由于JJG639-1998《医用超声诊断仪超声源》检定规程中并未明确规定,有可能导致测量结果不准确。一、关于输出声强检测时遇到的问题具备加彩功能的医用超声诊断仪超声源开启
With the rapid development of medical technology, medical ultrasonic diagnostic apparatus with color-increasing and frequency conversion functions has been widely used in medical institutions at all levels for clinical diagnosis and examination of pregnant women’s fetuses. Some settings of the instrument itself will have an impact on the measurement results. However, the JJG639-1998 Medical Ultrasound Ultrasound Source calibration protocol is not specified, which may lead to inaccurate measurement results. First, on the issue of output sound intensity detection problems with color-plus function of the medical ultrasound diagnostic ultrasound source open
