Feb 27, 2024 · X-ray technology lets doctors see straight through human tissue to examine broken bones, cavities and swallowed objects with extraordinary ease. Modified X-ray procedures can be used to examine softer tissue, such as the lungs, blood vessels or the intestines. In this article, we'll find out exactly how X-rays machines pull off this incredible ...
How do medical x-rays work? To create a radiograph, a patient is positioned so that the part of the body being imaged is located between an x-ray source and an x-ray detector. When the machine is turned on, x-rays travel through the body and are absorbed in different amounts by different tissues, depending on the radiological density of the ...
Aug 3, 2018 · The most relevant concept to understand how X-ray imaging works is the behavior of X-rays when they interact with matter. In this chapter, the physical principles of X-rays are introduced. We start with a general definition of X-rays compared to other well known rays, e. g., the visible light.

X-rays were discovered on November 8th, 1895 by German physicist Wilhelm Conrad Roentgen while he was experimenting with cathode ray tubes. A cathode ray tube is a sealed tube with all the air removed. At one end of the tube is an electron gun and at the opposite end of the tube is a screen on which images can be viewed. Roentgen noticed that photo...
An x-ray machine is essentially a specialized type of camera. Instead of having visible light expose the film and create an image, x-rays expose the film and create an image. Bone tissue, which contains a lot of calcium, absorbs a lot of x-rays, whereas soft tissues such as fat and skin do not. In an X-ray image, areas that contain less dense tissu...
X-rays are not just for checking for broken bones. Your dentist uses x-ray imaging to check for cavities in your teeth. Mammographers use low-energy x-rays to do mammograms, which help doctors check the health of breast tissue. Airport security uses x-ray machines to check luggage for dangerous objects. X-rays are also used as a form of non-destruc...
The benefit of x-ray imaging is that it is a very useful tool for looking at bones, as well as other hard tissues. This includes gallstones, which are crystals sometimes formed in the gallbladder. It also includes kidney stones, which are crystals sometimes formed in the kidneys. Other hard objects include cancerous tumours and accidentally swallow...
Apr 23, 2020 · Just like most cameras we use these days are digital, though, so are many modern x-ray systems. Pictures made using x-rays help doctors make many important diagnoses. They can help us see pneumonia in the lungs or a broken bone, just to name two examples.

X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film or digital media. Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries.
