X-ray

X-rays are electromagnetic waves with extremely short wavelengths and high frequencies, possessing strong penetration capabilities. It is electromagnetic radiation emitted by atoms during energy level transitions, with wavelengths ranging from 0.01 nanometers to 10 nanometers (corresponding to a frequency range of 30PHz to 30EHz). In medical diagnosis, X-rays are received by detectors after passing through the human body. The absorption degree of X-rays varies among different tissues in the human body. The detector converts the received intensity differences into corresponding electrical signals, which are then processed by a computer to generate images of the internal structure of the human body with different gray levels. In addition, high-dose X-rays can also be used for radiation therapy.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

X-rays are commonly used in the medical field for radiological diagnosis, which can observe the bones, organs, and other structures inside the patient's body and help diagnose diseases. On November 8, 1895, William Conrad Dr. R ö ntgen discovered "X-rays". On December 22 of the same year, R ö ntgen took X-rays of his wife's hands. This is the first X-ray of the human body, and the black object on the finger is a wedding ring.
