Mainly two aspects: structural parameters and electrical parameters.
The structural parameters refer to various parameters determined by the structure of the x-ray tube, such as the tilt angle of the target surface, the effective focus, the outline dimensions, the weight, the filtered lead equivalent of the tube wall, the anode rotation speed, the working temperature, the cooling and the dielectric strength.
The electrical parameters refer to the specifications of the x-ray tube electrical characteristics, such as filament heating voltage and current, maximum tube current, tube voltage, maximum exposure time, maximum power, and the like.
Although there are many parameters, pay more attention to the following parameters:
-
Maximum tube voltage
It is the highest voltage value applied between the two poles of the x-ray tube in kilovolts (kV). This value is determined by the length of the x-ray tube, the shape, the type of insulating medium, and the form of the sleeve. Exceeding the maximum tube voltage value will cause the discharge or break down of the x-ray tube.
-
Maximum tube current
It is the maximum average current value (mA) allowed under a certain voltage and exposure time. Do not exceed the rated value when adjusting the tube current, otherwise it will cause the focal surface to overheat and damage or shorten the life of the filament.
-
Longest exposure time
It is the maximum exposure time (s) allowed under a certain voltage and current, in seconds. Exceeding the maximum will cause heat accumulation and damage of the x-ray tube.
