Do I need to undress for X-ray?

You don't need to take off your clothes when taking X-rays.

X-ray is more economical and convenient, and the inspected parts can be changed at will for observation in many aspects, but no objective records can be left, and it is difficult to distinguish the details. Photographing can clearly show the structure of the examined part on the X-ray film, and can be kept as an objective record for a long time, so as to make comparison at any time when necessary.

When necessary, special X-ray examination can be carried out, such as tomography, waveform recording photography and contrast examination. The choice of X-ray examination method must be based on the specific conditions of examination, the requirements of solving diseases (especially orthopedic diseases) and clinical needs.

Extended data:

The simplest way to generate X-rays is to hit a metal target with accelerated electrons. During the impact, the electrons will suddenly decelerate, and their lost kinetic energy will be released in the form of photons, forming a continuous part of the X-ray spectrum. By increasing the accelerating voltage, the energy carried by electrons will increase, which may knock out the internal electrons of metal atoms.

So the inner layer forms a hole, and the outer layer electrons jump back to the inner layer to fill the hole, and at the same time emit photons with a wavelength of about 0. 1nm. Because the energy released by the outer electron transition is quantized, the released photon wavelength is also concentrated in some parts, forming a characteristic line in the X spectrum.
