Introduction in clinical practice of X-ray diagnostic sets powered with three-phase current PYM-20 and PYM-20M is followed by promoted capital investments in installations for X-ray departments. Hence, more stringent operational requirements should be placed upon new sets as compared to previous models. Based on the economic analysis two main approaches are considered: wide acceptance of multi-purpose X-ray sets commercially produced by the S. U. industry and operation on the two-shift basis.
在临床实践中引入由三相电流驱动的PYM - 20和PYM - 20M X射线诊断设备后，对X射线科室设备的资本投资增加。因此，与以前的型号相比，对新设备应提出更严格的操作要求。基于经济分析，考虑了两种主要方法：广泛采用苏联工业商业化生产的多功能X射线设备以及实行两班制运行。
