Radiology

It consists of obtaining images of the human body through the use of radiation emitted by radiology equipment also called X-rays.

The images are normally reproduced in the radiographic plates, which are the equivalent to photographic negatives of the explored area and the doctor studies them with a back light or negatoscope.

or negatoscope.

Radiology is the medical specialty that deals with generating images of the inside of the body by means of different physical agents (X-rays, ultrasound, magnetic fields, etc.) and using these images for diagnosis and, to a lesser extent, for the prognosis and treatment of diseases. It is also generically referred to as radiodiagnosis or diagnostic imaging.

Radiology must be distinguished from radiotherapy, which does not use imaging, but directly employs ionizing radiation (X-rays of higher energy than those used for diagnosis, and also radiation of other types) for the treatment of diseases (for example, to stop or slow the growth of tumors that are sensitive to radiation).

Many centers now have digital systems that allow X-rays to be viewed on computer screens.
