X-ray machine practitioners, so they are relatively familiar. In fact, the so-called portable X-ray machine should refer to the bedside X-ray machine in terms of large categories, which can be pushed to the ward for X-ray examination. Portable doesn't mean cheap. The best bedside machines on the market cost millions, and there is no so-called shrinkage in performance, but the application scenarios of fixed X-ray machines are different. Specialized image processing algorithms for images. And this kind of equipment is used more in some large hospitals, and can be placed in the operating room, ICU, and orthopedics to facilitate the use of bedridden patients. With the vigorous development of Chinese hospitals, this product has gradually become popular in hospitals below the second level.
The price of X-ray machine equipment depends more on the price of core components, such as tube, high voltage generator, detector. For example, in the past few years, some domestic brands of CCD detector X-ray machines have been widely used in some township-level hospitals because of their price advantages. You can buy one as low as 100,000 or 200,000. The actual exposure dose ratio is best equipped with a DR flat panel. The detector's mobile X-ray machine is much taller.
When it comes to the issue of radiation, with a qualified X-ray machine and a computer room with up to standard protection, the dose received by the staff is generally not high. The same is true for bedside filming, where technicians are generally farther away and wear lead clothing, and the radiation is negligible. So here we are talking about the dose of the patient, and in this respect, the detector material has a very large impact. As mentioned earlier, the CCD detector requires a much higher imaging dose than the CR and DR detectors. For bedside filming, the formal requirement is to place a lead screen next to the patient to prevent radiation to other patients.
