1, first of all, there is no negative difference. DR chest x-ray is after taking chest x-ray will give me a negative, and will show the corresponding report, while the ordinary chest x-ray is no negative, just the doctor in the room to give the photo after signing on the form on the end.
2, the price of the different, DR chest x-ray compared to the ordinary chest x-ray is more expensive, while the ordinary chest x-ray because of the development of technology has been very common, the cost of only about 10 dollars can be.
3, different uses. In the hospital patients to take a chest X-ray film generally refers to the DR chest X-ray, and ordinary chest X-ray is just a simple look at the chest cavity, so most of them are used as a physical examination.
Expanded Information
Both the DR chest x-ray and the regular chest x-ray utilize X-rays for examination, and X-rays are dangerous, so you should pay attention to the following points when using a chest x-ray:
1, with the continuous improvement of the X-ray instrument, its radiation dose is becoming more and more important, so it's important to pay attention to the following points:
1. The most important thing to remember is that the X-rays have been used for a long time and the radiation dose is getting smaller and smaller, plus the chest X-rays are usually within 10 seconds or less, so the harm to the human body is very tiny and basically negligible.
2, but because children are at the peak of growth and development, cell division is active, more sensitive than adults, and the younger the more sensitive, will cause some of the body cell damage, these damaged cells if not self-repair (may also be abnormal repair), will remain in the body, like a "ticking time bomb" in the The fact is, if you're not able to repair the damaged cells, they will remain in the body like a "time bomb" and start to replicate wildly in the presence of low immunity or cancer-promoting factors to become a cancerous tumor.
So the more radiological examinations you have, the greater the probability of inducing cancer. Distant after-effects can be induced in the next few decades after their radiological examination. The international standards for radiation health protection of children all clearly state that routine examinations of the lungs should not be used as a routine examination (e.g., physical examination) program for young children and adolescents. Children should be examined with radiographs as much as possible.
3, as far as possible to use the film instead of chest X-ray chest X-ray voltage, current are much weaker than the film, due to the intensity of the weak, the ray can not be as rapid as the film as the penetration of the human body, and therefore after the body of the time is relatively longer, the human body absorbed the dose is also more.
