六十年代初我科制成的电子管式心动周期X线摄片仪,曾试用检查一部分正常人及病例,但由于种种原因未能加以开展。在此基础上于一九七四年试制成功了小型晶体管式心动周期X线摄片仪,(其结构、原理、制作见另文发表)。一九七八年曾提供心动周期(收缩、舒张)两期X线摄片156例初步小结一文送交全国卫生系统科技大会,从七四年到八一年以该晶体管摄片仪对550例正常人及心血管病例作了收缩、舒张期(下简称为两期摄片)X线摄片,其中正常人126例(临床无自觉症状,客观检查阴性,从X线两期片观察均无心肺病变)。其余在病例组分别另文介绍。
In the early 1960s, our department made a tube-type electrocardiographic X-ray radiograph that had been used to examine some normal people and cases. However, they failed to be carried out due to various reasons. On this basis, a small transistor-based cardiac cycle X-ray radiograph was successfully trial-produced in 1974 (its structure, principle and production are shown in the separate article). In 1978, we provided a preliminary summary of 156 cases of two phases of cardiac cycle (systolic and diastolic) radiographs and sent them to the National Health System Science and Technology Conference. From 1974 to 1981, 550 cases Normal and cardiovascular cases were contracted, diastolic (hereinafter referred to as two radiographs) X-ray, of which 126 cases of normal (no clinical symptoms, objective examination was negative, both were observed from the X-ray films were Cardiopulmonary disease). The rest were introduced separately in case groups.
