The development of CT tubes is one of the expensive components in CT machines. The correct use of CT tubes will directly affect the smooth cessation of CT and medical work, and will have an impact on the economic and social benefits of hospitals. The correct use and maintenance of CT tubes play an indispensable role in extending their lifespan and improving image quality.

The factors that affect the lifespan of CT tubes are summarized as follows.

1. Warmup Scan Operation (WARMUP)

When CT pauses scanning for several hours and then stops scanning, it should follow the prompts of the machine to perform preheating scanning.

Preheating scanning is beneficial for extending the service life of the tube and ensuring good image quality.

2. Properly controlling exposure conditions

Based on the patient's age, weight, and scanning location, accurately set scanning conditions to reduce unnecessary tube loss and minimize the harm of excessive radiation to the patient and operator.

3. SCOUT VIEW length control

Accurately position the patient and identify the scanning area, while minimizing exposure to non examination areas.

4. Temperature, humidity and environmental control

During the exposure process, the tube will generate a large amount of heat, so it is necessary to equip a sufficient capacity air conditioning system, strictly control the temperature and humidity of the scanning room according to rules, and ensure the circulation of air in the scanning frame, which will be beneficial for the effective heat dissipation of the tube.

5. Reduce the air consumption of rotary anode (ROTOR) and filament

When the scanning program is in the "ready" state, the exposure scanning should be stopped immediately. At this time, the rotating anode of the tube has accelerated to a high speed of 10000r/min, and the filament has also been heated to the required temperature for exposure. If the tube R&D does not stop exposure in time, it will result in tube depletion.

6. Good maintenance

Proper preventive maintenance of equipment, especially the high-pressure control system of the ball tube, is an important element in ensuring the operation of the ball tube.

7. Good operating procedures

Develop and strictly implement operating procedures, develop CT equipment for mid-range ball tubes, and wait for at least 20 minutes before turning off the control power each time to allow the ball tubes to cool sufficiently. Stop using high-power radio equipment such as mobile phones in the CT room to prevent interference with equipment and damage.
