Have you ever wondered what lies beneath your skin? X-rays can tell you exactly that. During an X-ray examination, a specially trained physician can see exactly what your bone structure looks like and interpret what this imaging reveals. The discovery of X-rays by Wilhelm Conrad Röntgen in 1895 was a milestone that served the prevailing curiosity about the inside of the human body – it allows us to literally look beneath the skin. This article by Animus Medicus introduces you to the world of X-rays and explains what to expect during an X-ray examination. This way, you can look forward to your next X-ray examination with confidence and learn some exciting things about X-ray technology.

What are X-rays?

X-rays are a form of electromagnetic radiation, similar to the light we see or the radio waves that transmit music and news. The difference lies in their wavelength: X-rays are much shorter, which gives them the ability to penetrate certain materials, such as our body. X-rays were discovered accidentally by the physicist Wilhelm Conrad Röntgen, who noticed a mysterious radiation that blackened photographic plates while experimenting with cathode ray tubes. Röntgen's discovery revolutionized physics and also became an indispensable tool in medical diagnostics to this day.

How an X-ray Machine Works

The function of an X-ray machine is to create an image of something that lies beneath an opaque surface. A classic X-ray machine in medicine is essentially a tube that shoots electrons at a piece of metal. Upon impact of the electrons, X-rays are generated, which are passed through the body to be examined. Because different materials absorb the rays differently, an image is created on a so-called detector or photographic plate. The bones are depicted in white, soft tissue in shades of gray, and air in black. Nowadays, digital X-ray techniques are able to convert these rays directly into images that are displayed on a screen. This modernization enables immediate evaluation of the imaging by the physician.

X-ray explained: This is how the process works

Those who have never experienced an X-ray examination on their own body may have no idea about it. Here you will find an explanation of the X-ray examination procedure:

• Once it's your turn for your X-ray, you will often be led into a regular examination room before entering the room containing the X-ray machine. Often, the X-ray procedure will be briefly explained to you again.

• You may be asked to remove certain items of clothing, such as your medical socks in the case of foot injuries, and to change. You should also remove personal items such as your anatomical jewelry and piercings before the X-ray. Although X-rays can be harmful in high doses, the amounts used in a typical X-ray are very small. Nevertheless, for safety reasons, lead aprons or other protective measures are used to shield body parts not being examined.

• An X-ray is quick and painless. You will be asked to remain still, either standing or lying down, for a clear image capture while the X-ray machine is briefly activated. Your position will depend on the body part being imaged. The medical staff will help you position yourself to achieve the best possible image. During the short time the image is being taken, it is essential that you remain perfectly still to ensure a clear picture.

• Once the images are taken, you may get dressed and leave the room. The entire procedure often takes only a few minutes, and the results are evaluated by a radiologist who will discuss the findings with you and your physician.

Understanding Anatomy Through X-ray Imaging of Bones

What's remarkable about X-rays is how they reveal the hidden structures of our bodies. They enable doctors to diagnose bone fractures, locate foreign bodies, or assess the health of joints. X-rays are not limited to the human body. Insights into the anatomy of animals are also possible with X-ray technology, which is essential for veterinary diagnoses. X-ray imaging is not only of interest to medical professionals but also fascinates the general public, as it makes something visible that is not perceptible to the naked eye.

The Importance of X-rays for Diagnosis

X-rays are often the first step in the diagnostic process. Without them, often only a guess can be made about an existing fracture. The anatomical images of such an X-ray can provide information about conditions that cannot be determined by external examination methods. This includes, for example, the presence of tumors, the extent of an infection, the presence of a bone injury, or the stage of a disease. The interpretation of X-ray images, however, requires expertise, as despite X-rays, anomalies in bone and other parts of the human anatomy are not always easy to recognize and interpret. Your X-ray results will then be explained to you in detail by your specialist, who will recommend further treatment.

X-rays Beyond Medicine

The application of X-rays is not limited to the medical field. Here are some other exciting applications of X-rays briefly explained:

• Analysis of artwork and archaeological finds, by using X-rays to reveal hidden layers and previous modifications and to estimate the age of bones based on their condition.
• Examination of material structures and the detection of defects in industry. Using X-rays, cracks or air pockets can be detected. This allows for the sorting out of defective materials.
• Detection and prevention of hazards in security technology, such as at airports. Objects and clothing are screened for hazardous materials.
• Many other areas such as geology, astronomy and industry

The indispensable technology of X-rays

X-ray equipment and its function give us deep insights into the world around us and within ourselves. This technology has revolutionized medical diagnostics and is used in many other areas.
