QUESTIONNAIRE OF DIAGNOSTIC X-RAY GENERATORS AND X-RAY TUBES

Abstract

A questionnaire about X-ray generators and X-ray tubes was issued to the nation wide members of the JSRT by Radiography and X-ray Generator Characteristics Study Group. Thirty three answers returned and the percentage was 47. The questions are about hospitals, numbers of generators and their models, power supply, X-ray tubes, the dynamic characteristics of generators and radiographic shortest exposure time, etc. The result shows that they have 159 of 12 peak, 36 of 6 peak, and 325 of 2 peak generators. Three phase 12 and 6 peak generators are doubled in numbers compared with our former survey in 1975. The dynamic characteristics of X-ray generators show less improvement than former one. To solve this problem, both user and manufacturer must pay more attention to the characteristics, technologically in radiography and in the design field.
