When we consult or purchase X-ray machines, we will hear 50 mA, 100 mA, 200 mA, 500 mA and so on. What does this 500 mA X-ray machine refer to?
In fact, this 500 mA X-ray machine has no special meaning, it refers to electric current. We know that a 500 mA X-ray machine has power. Generally speaking, the greater the power, the higher the price. The power is obtained by multiplying kv and ma, where kv refers to the intensity of the ray. The larger the KV, the stronger the penetrating power of the ray; and ma refers to the density of the ray. Under the same kv condition, the larger the ma, the greater the density of the ray, and the clearer the image. Generally, the kv and ma of an X-ray machine are adjustable, but under the condition of rated power, kv and ma are inversely proportional. Therefore, if you want a clearer image, you still have to buy a machine with a higher power. Therefore, when buying an X-ray machine, be sure to ask about the power rather than how many milliamps.
