We have conducted a questionnaire survey every 5 years from 1974 to grasp the existing status of X-ray equipment. This time, we will report on the results of the fiscal 2015 diagnostic X-ray equipment questionnaire survey. Compared to the previous survey on X-ray equipment, there has been a progress in the introduction of inverter type X-ray generators and image receptor systems in digital systems. We think that this transition will be occurred when the X-ray equipment are updated. In addition, there has been an increase in digital breast tomosynthesis (DBT) and the use of tungsten anodes in the X-ray tubes of mammography apparatuses. X-ray equipment management was performed in many facilities. It seems that the importance of quality control of X-ray equipment is being realized. Constancy tests corresponding to digital systems were conducted at each facility. Maintenance by manufacturers has also increased. This is considered to be because the equipment management of digital systems has become difficult. We believe that it is necessary to continue the survey on the status of diagnostic X-ray equipment.
自1974年起，我们每5年进行一次问卷调查，以掌握X射线设备的现状。此次，我们将汇报2015财年诊断用X射线设备问卷调查的结果。与之前的X射线设备调查相比，数字系统中逆变器型X射线发生器和图像受体系统的引进有了进展。我们认为，这种转变将在X射线设备更新时发生。此外，数字乳腺断层合成（DBT）以及乳腺摄影设备X射线管中钨阳极的使用有所增加。许多机构都进行了X射线设备管理。似乎X射线设备质量控制的重要性正在得到认识。各机构都进行了与数字系统相应的稳定性测试。制造商的维护工作也有所增加。这被认为是因为数字系统的设备管理变得困难。我们认为有必要继续对诊断用X射线设备的状况进行调查。
