CSZ-2型超声波诊断仪是一种利用超声波脉冲反射方法对人体各脏器进行探测的仪器,亦称A型诊断仪。它是将超声波脉冲射入人体内腔,在脏器(或病变)间的复杂界面反射各种回波,经放大以后,显示在示波器萤光屏上,然后根据这些反射讯号波形的形态、位置、幅度以及数量,从而判断人体内脏的性质,如炎症、溃烂、癌肿、结石等。仪器分1.25MC(主要探查颅脑等),2.5MC(主要探查内脏软组织等),5MC(主要探查眼球等)三种频率。
CSZ-2-type ultrasonic diagnostic apparatus is a use of ultrasonic pulse reflection method of detection of various organs of the human body, also known as A-type diagnostic apparatus. It is the ultrasound pulse into the body cavity, complex interface between organs (or lesions) reflect a variety of echoes, after amplification, displayed on the oscilloscope screen, and then according to the shape of these reflected signal waveform, location , Magnitude and quantity, to determine the nature of human organs, such as inflammation, ulceration, cancer, stones and so on. Instrument sub-1.25MC (mainly to explore the brain, etc.), 2.5MC (mainly to explore the visceral soft tissue, etc.), 5MC (mainly to explore the eye, etc.) three frequencies.
