X ray imaging involves electromagnetic waves or radiation used to create pictures of the internal parts of the body. The images show your body parts in various shades of black and white. The reason is that tissues can absorb different levels or amounts of the x ray beam.

The most familiar use of X ray examination is checking for fractured bones. However, health professionals also use it in many other ways, for example, to spot pneumonia. Research shows that mammograms also use X-rays to diagnose breast cancer.

In today’s article, we will talk about what X-ray is, how this imaging test works, its history, applications, and more.



Marie Curie made huge contributions to the field of chemistry and physics. She also played a key role in the world of medicine, and specifically in radiology. Curie had thoroughly studied x-ray imaging and machines in her research during the First World War where she made a few advances in this field.

She worked on the X-ray machine discovered by Wilhelm Roentgen. She used her newly discovered radium, as a source of gamma-rays on X-ray machines. The purpose of using radium on the machine was to produce stronger and more accurate images of the body tissues.

キュリーはまた、現場で働く医療従事者向けのポータブルX線装置も作成していました。彼女の信じられないほどの仕事は、戦争中に多くの命を救った何千人もの医者を助けました。 1946年、フェリックスブロッホとエドワードパーセルは独立して核磁気共鳴(NMR)を発見しました。 1952年、これらのアメリカの物理学者は、医用画像への並外れた貢献によりノーベル賞を受賞しました。


In general, the x ray machine relies on electromagnetic radiation, which is generated by an x ray tube, projected towards the patient undergoing the diagnostic imaging procedure. It is imperative to know that you can’t see X-rays with the naked eye. When these waves pass through the body, the energy, or radiation, is absorbed at various rates by different organs and tissues of the body.

A detector picks up the X-rays and turns them into an image. Some parts of the body are dense, which don’t allow the X-rays to pass through them easily. For example, a bone x ray will often reveal a clear image.

On the other hand, soft parts of the body allow X-rays to pass through them more easily. The heart, lungs, kidneys, liver, etc. are examples of soft tissue and show up as darker areas on the radiological image.


Like Gamma rays, it is not possible to see, feel, and hear X-rays. However, these waves or radiations can easily pass through skin, bone, and metal to generate images that the naked human eye would never see. Anyway, here are a few applications of X-rays.

Fractured Bones: Undoubtedly, X-ray machines are an integral component of medical institutions and centers. The most common application of X-rays is to detect broken bones in the body. A health professional places a photographic film behind the body and turn on the X-ray machine.

Radiation Therapy: X-rays also play a key role in the fight against cancer. Radiation exposure using high-energy waves has been proven to kill cancer cells and reduce the intensity of tumors. Remember, radiation therapy is dangerous, but still, over 50% of cancer patients receive it regularly.

Airport Security: The security system of most airports around the world is incomplete without the implementation of X-ray machines. The security staff uses the machine to scan baggage and check for illegal items. Many airports are also using full-body X-ray scans to enhance their security measures.




X線イメージングデバイスおよびマシンを使用することにはいくつかの利点があります。たとえば、それらを使用して人体の画像を作成し、健康上の問題を除外して障害を診断することができます。 X線は、放射線療法、空港のセキュリティ、偽の芸術の公開にも使用されます。
