Hardware maintenance of DR

In recent years, with the continuous breakthrough of digital imaging technology, DR equipment has been rapidly developed and popularized with its unique advantages. As we all know, the daily care of medical devices is the key to prolong the service life, so, what work should be done in the maintenance and maintenance of DR equipment?
First of all, DR should have a good clean environment, and often keep clean, strictly dustproof, to prevent pollution. Second, vibration can also affect the rack and plate detectors, so it is important to prevent vibration caused by collision between the detector and the detector housing during the actual operation. Moreover, temperature and humidity are also important factors that affect the normal operation of electrical system and plate detector. In the south of China, the failure probability of flat panel detectors is much greater than that of the north, and the high occurrence period is mainly the annual plum rain season. Therefore, it is recommended that hospital equipment rooms be equipped with air conditioners and dehumidifiers, especially in areas with high humidity.
In addition, the calibration is a very important part of DR daily maintenance, and the equipment needs to be calibrated regularly. The calibration mainly includes: ball tube calibration and plate detector calibration, and plate detector calibration mainly includes gain calibration and defect calibration. Usually the calibration time is set as six months, if there are special circumstances, it should be performed once every three months. The calibration operation should be carried out by professional engineers. Others should not operate at will.
The startup and shutdown of the DR system is also very important. Although it seems to be a simple operation, it has a significant impact on the incidence of failure and the service life of the DR equipment. Therefore, before starting the machine, we should first turn on the air conditioner and dehumidifier in the room, and then start the machine when the room environment meets the requirements of the device. Shutdown should be the first to exit the system, and then cut off the power, so as to avoid the loss of software and data. At the same time, let the machine stop working (after exposure) standby for a period of time and then shut down, let the cooling fan continue to work for a period of time to heat the machine.
As a precision instrument, the maintenance of mechanical parts of DR equipment can also not be ignored: for example, pay attention to the work of the moving parts is normal, pay special attention to the wear of the wire rope, if there is a burr phenomenon should be replaced in time, and regularly wipe and add lubricating oil, such as bearings, etc.
In order to ensure the normal operation of the DR equipment, prolong the service life of the machine, improve the image quality, we must develop the habit of caring for the machine, rational use of the machine, scientific maintenance of the machine, so as to maximize the use efficiency of the equipment.
