The system of line.
Its course of work is：Heated by 12V electric currents for cathode filament, and produce free electronics and converged, at this moment to negative and positive
When the two poles of the earth add 40 1 150kV high-tension electricities, electrical potential difference increases suddenly, under High Voltage electric field driven, the free electron in active state
Beam, by negative electrode high-speed impact anode molybdenum-base tungsten target, and occurs energy conversion, about l% electric energy forms x lines, launched by window,
99% is converted to heat energy, is distributed by cooling system.X lines are a kind of short electromagnetic waves for having a very strong penetrating power, and voltage is higher wears
Saturating power is stronger.X lines can be decay by the absorption of part during penetrating material, and this is the foundation of physics of x-ray imaging.Utilize
This principle makes the tissue of human body produce the ray projection of differential declines, makes the silver bromide of film photosensitive developed in black；And
Not photosensitive silver bromide, is transparent whites through fixing bath, black-and-white image is thereby produced, here it is photoeffect.Other x lines
Penetration level it is related also to the density and thickness of photographed object by attenuation by absorption degree in other words, shown black and white shadow in imaging
Level difference represent the density variation of tissue, density is higher, absorbs more, penetrates fewer, and photosensitive fewer, image is got over
In vain；It is on the contrary then more black.Density also changes when lesion occurs for tissue, and the black and white shadow of its image also changes therewith, and this is just
It is diagnostic imaging principle.
The current state-of-the-art technology of target disc cooling structure is embedded solid fin and the combination knot of bottom water cooling in anode water cooling
Structure, the heat that target disc is produced is conducted to bottom cycle water progress circulating cooling again by being conducted to fin.Because being carried out with target disc
Direct heat exchange is solid fin, so heat exchanger effectiveness is not high.
This patent is introduced into runner in the fin of direct heat exchange, substantially increases heat exchange efficiency, improves CT bulbs
Life-span.
