[Practical methods used in the system of controlling of x-ray apparatus].

An x-ray apparatus like any other device becomes worn out. In order to avoid x-ray examinations of patients performed using a worn out apparatus a periodical control of such appliances should be carried out. This work presents a methodology based on simple quality tests for a standard x-ray apparatus. These tests measure parameters of x-ray tubes and beams of radiation. A positive feature of these tests is that they replace very expensive specialistic measuring equipment.
