What images does an x-ray show?

X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white.

Are x-rays photographs?

Images created using this technique are called radiographic images (or radiographs). X-ray images are still pictures similar to photographs. Fluoroscopic images are moving pictures similar to movies. Tomographic images are visualized ‘slices’ of the body.

How does x-ray photography work?

Today’s x-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. When x-rays come into contact with our body tissues, they produce an image on a metal film. Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them.

Which of the following is used in photography and x-ray films?

Assertion: AgBr is used on photographic and x-ray film. Reason: AgBr is photosensitive and changes to Ag and bromine in presence of sunlight and undergoes decomposition reaction.

How do X-rays produce images?

X-rays are a form of electromagnetic radiation, similar to visible light. If x-rays travelling through the body also pass through an x-ray detector on the other side of the patient, an image will be formed that represents the “shadows” formed by the objects inside the body.

What does X mean in X-ray?

Röntgen referred to the radiation as “X”, to indicate that it was an unknown type of radiation. The name stuck, although (over Röntgen’s great objections) many of his colleagues suggested calling them Röntgen rays.

How is an X-ray image made?

An X-ray is produced when a negatively charged electrode is heated by electricity and electrons are released, thereby producing energy. However, bone absorbs X-ray energy and does not expose the film. This area appears light or white on the film. This is how an X-ray image is created!

What is X-ray film used for?

The X-ray film is the medium that record the image of part exposed with X-rays. The x-ray film is somewhat similar to photographic film in its basic composition.

What is the coating on X-ray film?

A modern x-ray film consists of a radiation-sensitive emulsion coated on a transparent polyester base. The emulsion consists of silver halide crystals (typically 95\% silver bromide and 5\% silver iodide) and gelatin which provides the suspension medium for the silver halide grains.
