A型超声视轴回声图国内有所报道,所测结果因方法、测量精度不同而略有差异。在近视防治工作中,我们测量358例少年学生716(眼)的视轴A超回声图并对其进行分析,报告如下。一、仪器、方法与受检者1.仪器:采用国产CTS-5型超声诊断仪(汕头超声电子仪器厂生产),探头直径8mm,频率5cm,工作状态Ⅰ级,增益7,抑制8,屏幕聚焦清晰,辉度为上限值。为使读数更为准确,在基线屏幕下方贴
A-type ultrasound borescope echo reports have been reported in the country, the measured results due to the method, the measurement accuracy is slightly different. In the prevention and treatment of myopia, we measured and analyzed the visual axis A-hyperechogenic diagram of 716 (eyes) of 358 juvenile students. The report is as follows. First, the instrument, methods and subjects 1 instrument: using domestic CTS-5 ultrasonic diagnostic apparatus (Shantou Ultrasonic Instrument Factory), the probe diameter 8mm, frequency 5cm, working state Ⅰ level, gain 7, inhibit 8, the screen Focus on clarity, brightness is the upper limit. To make the reading more accurate, paste below the baseline screen
