In X-ray photography, the X-ray quality is represented by the following items.

In X-ray photography, the quality of X-rays is expressed in electron volts, that is, the voltage of X-rays. X-rays are produced by electrons hitting the target under the action of high-voltage electric field, and their energy is proportional to the voltage. In X-ray photography, by controlling the voltage of X-ray, the penetration depth and quality of X-ray can be controlled, so as to achieve different imaging effects.

X-ray photography is a kind of medical imaging technology, which uses the characteristics of X-ray penetrating objects to visualize the bones, soft tissues and other structures inside the human body for clinical diagnosis and treatment. In X-ray photography, the patient needs to expose a specific part in front of an X-ray device, and the X-ray will penetrate the patient's body and be received by the detector.
