Tube is one of the expensive and consumable parts in CT machine. Its use will directly affect the smooth operation of CT and medical work, and will have an impact on the economic and social benefits of the hospital.CT tubeThe elements of longevity are summarized as follows, for your reference:

1, Warm up scan operation (WARMUP)

When the CT scan is stopped for several hours and then scanned again, the preheating scan should be performed according to the prompt of the machine.

Scanning is beneficial to prolong the life of the tube and ensure good image quality.

2, Correctly control the exposure conditions

According to the patient's age, fat and thinness and scanning position, the scanning conditions can be set accurately, so as to reduce the inadvertent loss of the tube, and at the same time reduce the harm of excessive radiation to the patient and the operator. The "SMARTSCAN" function used in high-end machines can ensure Under the premise of image, automatic adjustment of exposure dose in scanning is an effective way to extend the tube.

3, Control the length of the positioning image (SCOUTVIEW)

Accurately place the patient's body position and confirm the scanning part, and minimize the exposure of the non-examination part. Prevent "pulling the big net and catching small fish".

4, Temperature and humidity and environmental control

The tube will generate a lot of heat during the exposure process. Equipped with an air-conditioning system with sufficient capacity, strictly control the room temperature and humidity of the scanning according to the rules, and ensure the circulation of air in the scanning frame, which will be conducive to the effective heat dissipation of the tube. At the same time, insist on indoor Clean, reduce the entry of dust, can prevent dust from clogging the tube radiator.

5, Reduce the empty consumption of the tube rotating anode (ROTOR) and filament

When the scanning program is in the "ready" state, the exposure scanning should be stopped immediately. Therefore, the rotating anode of the tube has been accelerated to a high speed of about 10,000 revolutions per minute, and the filament has also been heated to the temperature required for exposure. If the exposure is not stopped in time , which will form the empty loss of the bulb.

6, well maintained

Doing a good job in preventive maintenance of the equipment and ensuring the overall good condition of the equipment, especially the high pressure control system of the tube, is an important element to ensure the operation of the tube.

7, the power grid is stable and clean

The stability, cleanliness and sufficient capacity of the power supply system are guaranteedCT tubeAnd the necessary conditions for the stable operation of the system. To prevent other large-capacity equipment, especially thyristor chopper or medium and high frequency speed regulation, the temperature regulation system uses the same power supply circuit, because it may cause violent shaking or distortion of the power grid.

8. Reasonable arrangement of patients

According to the different scanning parts of the scheduled patients, the patients who need high dose exposure and the patients who need low dose exposure are interleaved. Let the tube have a chance to breathe.

9, Good operating procedures

Formulate and strictly implement operating procedures. Before turning off the control power for medium and low-grade CT equipment, wait at least 2 minutes or more to letCT tubeAdequate cooling. It is forbidden to use high-power wireless equipment such as mobile phones in the CT room to prevent interference with the equipment and cause damage.
