The performance parameters of some of the devices in the machine are shifted, which is mainly manifested as a shallow loop or other artifacts on the CT scan image, and the CT value error is large. At this time, the machine can be adjusted accordingly. This kind of situation has occurred many times on the Technicare2060Q in the United States and the SCT-4800T machine in Japan, and it can return to normal after being corrected by the CT value of the linear or air and water. Sometimes the entire system needs to be calibrated.
Failure caused by poor machine contact and dust. Various plug-in boards and interfaces in the machine may have poor contact after long-term use, especially in places with vibration. This kind of failure mostly appears on the machine that has been used for a long time, mainly manifested as a certain type of failure randomly, sometimes good and bad. The author has repeatedly encountered poor contact in the data collection channel of the machine. According to the fault performance and prompts, the corresponding plug, interface and slot can be restored to normal after processing.
The failure caused by machine dust is similar to the above performance, and it mostly occurs in the air intake part of the machine heat dissipation. The author encountered an unsteady failure of the SCT-4800T machine, sometimes manifested as a CPU control failure, sometimes an image reconstruction failure, and sometimes an image display failure. Finally, it was found that the air intake part of the cooling fan port under the control board in the console was covered with dust. Due to the high degree of circuit board integration and wiring density, the performance of the machine is unstable, and it can be solved by cleaning.
Software failure The CT machine has a very large system and control software for each part of the periphery. Most of the peripheral control software is stored in the chip in the form of ROM, and generally there will be no problems.
