  • X-rays are produced by interaction of accelerated electrons with tungsten nuclei within the tube anode
  • Two types of radiation are generated: characteristic radiation and bremsstrahlung (braking) radiation
  • Changing the X-ray machine current or voltage settings alters the properties of the X-ray beam

X-rays are commonly produced in X-ray tubes by accelerating electrons through a potential difference (a voltage drop) and directing them onto a target material (i.e. tungsten). The incoming electrons release X-rays as they slowdown in the target (braking radiation or bremsstrahlung).

How does an X-ray machine produce an image?

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. Dense materials inside our bodies, like bones, absorb the radiation.

How X-rays are produced step by step?

Summary of steps Filament current applied through tungsten filament at cathode. Heats up filament to produce enough energy to overcome binding energy of electrons (thermionic emission). Electrons released from filament. Tube voltage is applied across the x-ray tube.

What part of the X-ray machine produces X-rays?

X-rays can be generated by an X-ray tube, a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity. The high velocity electrons collide with a metal target, the anode, creating the X-rays.

How does X-ray Machine Work?

The X-ray tubes in the X-ray machine works by accelerating electrons under high voltage. These electrons will cause the breaking of atomic bonds, so it continuously releases electromagnetic radiation. This radiation causes further collisions with other atoms in its path. These types of collisions result in the emission of more X –rays and gamma rays. X-Ray screens are made from materials such as molybdenum or tungsten.

What is an X-ray machine?

X-ray machines are X-ray imaging devices. X-rays are a form of electromagnetic radiation that has been used in the medical field for many years now. This technology has proven to be very effective at showing us images of our internal organs such as lungs, heart, and even bones.

What do X -rays do to your body?

X-rays are electromagnetic radiation, and they can bounce off of different types of materials. Some materials have high density, while others are less dense.

Where to buy X-ray machines?

But it is always advisable to buy brand new X-ray machines for sale. This is because you will get a chance to use an X-ray machine in perfect condition to execute its mandate. Therefore, ensure that you buy from reliable X-ray machine manufacturers and suppliers in China.

How long should you leave your body exposed to X-rays?

Using exposure factors, they determine how long they will leave X-rays on exposing your body part. Usually, anything over 20 seconds is considered unsafe, but sensitive areas like your lungs may be X-rayed for up to 30 seconds.

What are the components of an X-ray tube?

X-ray tube has two components, X-ray target and X-ray cathode X-ray tube also called X-ray source. X-ray machines use X-ray tubes that are made of molybdenum or tungsten. X-rays will be produced when a high voltage is applied to the X-ray target. This X-ray will then pass through the X-ray control panel, a system used for regulating various settings on an X-ray tube.

Why is it important to only use X-rays?

It is very important that you only use X-rays when there is a need since they can do much harm should they be designed or controlled improperly. This is why we insist that you should buy quality X-ray machines for sale.

How does a radiograph 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 tissues they pass through.

Why do we need x-rays?

Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body. 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 ...

What are the structures that are whiter on a radiograph?

As a result, bony structures appear whiter than other tissues against the black background of a radiograph. Conversely, x-rays travel more easily through less radiologically dense tissues such as fat and muscle, as well as through air-filled cavities such as the lungs.

What is the difference between X-ray and mammography?

X-ray radiography: Detects bone fractures, certain tumors and other abnormal masses , pneumonia, some types of injuries, calcifications, foreign objects, dental problems, etc. Mammography: A radiograph of the breast that is used for cancer detection and diagnosis.

What is CT imaging?

CT (computed tomography ): Combines traditional x-ray technology with computer processing to generate a series of cross-sectional images of the body that can later be combined to form a three-dimensional x-ray image. CT images are more detailed than plain radiographs and give doctors the ability to view structures within the body from many different angles.

How is radiological density determined?

Radiological density is determined by both the density and the atomic number (the number of protons in an atom’s nucleus) of the materials being imaged. For example, structures such as bone contain calcium, which has a higher atomic number than most tissues.

Is radiation used for cancer?

The radiation dose used for treating cancer is much higher than the radiation dose used for diagnostic imaging. Therapeutic radiation can come from a machine outside of the body or from a radioactive material that is placed in the body, inside or near tumor cells, or injected into the blood stream.

How are X-rays generated?

X-rays are generated via interactions of the accelerated electrons with electrons of tungsten nuclei within the tube anode. There are two types of X-ray generated: characteristic radiation and bremsstrahlung radiation.

How is the X-ray spectrum manipulated?

This spectrum can be manipulated by changing the X-ray tube current or voltage settings, or by adding filters to select out low energy X-rays.

Why do radiographers change the current and voltage settings on X-ray machines?

Radiographers can change the current and voltage settings on the X-ray machine in order to manipulate the properties of the X-ray beam produced. Different X-ray beam spectra are applied to different body parts.

What are the two types of radiation?

Two types of radiation are generated: characteristic radiation and bremsstrahlung (braking) radiation. Changing the X-ray machine current or voltage settings alters the properties of the X-ray beam. X-rays are produced within the X-ray machine, also known as an X-ray tube. No external radioactive material is involved.

What happens when a filament voltage increases?

A small increase in the filament voltage ( 1) results in a large increase in tube current ( 2 ), which accelerates high speed electrons from the very high temperature filament negative cathode ( 3) within a vacuum, towards a positive tungsten target anode ( 4 ). This anode rotates to dissipate heat generated. X-rays are generated within the tungsten anode and an X-ray beam ( 5) is directed towards the patient.

How does an X-ray work?

Remember photons and electrons – atoms and molecules and nuclei? An X-ray is produced when a negatively charged electrode is heated by electricity and electrons are released, thereby producing energy. That energy is directed toward a metal plate, or anode, at high velocity and an X-ray is produced when the energy collides with the atoms in the metal plate.

When was the X-ray machine invented?

The X-ray was accidentally discovered by Wilhelm Roentgen, a professor of physics in Wurzburg, Bavaria in 1895 during an experiment. In 1896, the first radiology department was established at the Glasgow Royal Infirmary. Soon, X-ray machines were being used for many things, such as diagnosing fractures in the bones and to locate bullets during WWI. This one discovery advanced the field of medicine in a very big way. To be able to see the structure inside a person without blood loss from an incision was revolutionary.

What is X-ray scanner?

X-rays are also used in a CT scanner, or computed tomography. This modality uses multiple X-rays during one scan, to give a layer-by-layer image. X-rays are also being used in non-medical areas, like airport security and by NASA in outer space.

Does bone absorb X-rays?

This appears dark on the film as it is now exposed. 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!

How do X-ray machines work?

X-ray machines work by generating an electrical current or voltage, which is then projected through an X-ray tube to produce a series of X-ray waves, which either pass through objects or are absorbed by the surrounding material. X-ray machines essentially produce small amounts of radiation, which are transmitted to surfaces, such as tissue, bone and joints. While some beams pass through these objects, others are absorbed; this pattern of reflection and absorption produces an image on a special X-ray film.

What is X-ray machine?

X-ray machines are designed to permeate the surfaces of lighter objects and materials, such as skin and soft tissues. While beams pass easily through these body parts, they are not absorbed by denser materials, such as bone. The reflection of X-ray beams from dense objects appears as light areas on X-ray films, which identify bone structures and illuminate the skeleton.

How are visible light and X-rays produced?

Visible light photons and X-ray photons are both produced by the movement of electrons in atoms. Electrons occupy different energy levels, or orbitals, around an atom's nucleus. When an electron drops to a lower orbital, it needs to release some energy -- it releases the extra energy in the form of a photon.

What is X-ray technology?

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.

How do photons absorb energy?

When a photon collides with another atom, the atom may absorb the photon's energy by boosting an electron to a higher level. For this to happen, the energy level of the photon has to match the energy difference between the two electron positions. If not, the photon can't shift electrons between orbitals.

Why do radio waves pass through things?

Radio waves don't have enough energy to move electrons between orbitals in larger atoms, so they pass through most stuff. X-ray photons also pass through most things, but for the opposite reason: They have too much energy.

How does fluoroscopy work?

In fluoroscopy, the X-rays pass through the body onto a fluorescent screen, creating a moving X-ray image. Doctors may use fluoroscopy to trace the passage of contrast media through the body. Doctors can also record the moving X-ray images on film or video.

What did Roentgen see on the X-ray screen?

Finally, he put his hand in front of the tube, and saw the silhouette of his bones projected onto the fluorescent screen. Immediately after discovering X-rays themselves, he had discovered their most beneficial application.

What is the difference between X-rays and visible light rays?

The difference between X-rays and visible light rays is the energy level of the individual photons. This is also expressed as the wavelength of the rays.

How does an image get produced during an X-ray?

X-rays use beams that come into contact with the tissue in the body, certain tissue absorbs the high-energy rays differently and can result in the beam passing through them, dense material absorb the beams and show up clearly on the produced image on a metal film.

How long does it take to feel an X-ray?

You cannot feel an X-ray, it is completely painless. It can take a few minutes (mostly for teeth and bone X-rays), or may even take more than an hour (specifically for treatments using a contrasted medium). When your radiologist is happy with the images that have been captured, your test is finished.

What happens if a child has an X-ray?

If a child has an X-ray, they may be kept in place with certain restraints, in order to keep them as still at possible. The restraints will not harm the child. The parent is sometimes allowed to stay with them for the duration of the test – in this situation, the parent may be asked to wear a lead apron to shield them from unnecessary and possible exposure to radiation which X-rays give off.

How to position your body for an X-ray?

Once you are ready and prepared, the radiologist or X-ray technician will direct you on how to position your body. You may have to stand, sit or even lie down. You will have to stay extremely still in order to get a clear X-ray image. The radiologist may even use pillows to help to hold you in place. It is sometimes necessary to hold your breath in order to be extremely still.

Do radiologist use pillows?

The radiologist may even use pillows to help to hold you in place. It is sometimes necessary to hold your breath in order to be extremely still. In some cases, you may be asked to stand in front of a specialised plate containing sensors or X-ray film.

What is X-ray machine used for?

The main fields in which x-ray machines are used in medicine are radiography, radiotherapy, and fluoroscopic-type procedures. Radiography is generally used for fast, highly penetrating images, and is usually used in areas with a high bone content but can also be used to look for tumors such as with mammography imaging.

Who made the first X-ray machine?

One of the first X-ray photographs was made of the hand of Röntgen's wife. The image displayed both her wedding ring and bones. On January 18, 1896 an X-ray machine was formally displayed by Henry Louis Smith. A fully functioning unit was introduced to the public at the 1904 World's Fair by Clarence Dally.

How does a baggage detector work?

There is an infrared transmitter and receiver assembly to detect the baggage when it enters the tunnel. This assembly gives the signal to switch on the generator and signal processing system. The signal processing system processes incoming signals from the detector and reproduce an image based upon the type of material and material density inside the baggage. This image is then sent to the display unit.

What is an X-ray imaging system?

An X-ray imaging system consists of a generator control console where the operator selects desired techniques to obtain a quality readable image (kVp, mA and exposure time), an x-ray generator which controls the x-ray tube current, x-ray tube kilovoltage and x-ray emitting exposure time, an X-ray tube that converts the kilovoltage and mA into actual x-rays and an image detection system which can be either a film (analog technology) or a digital capture system and a PACS .

What material is used to make X-rays?

Due to the high energy of the electrons that reach relativistic speeds the target is usually made of tungsten even if other material can be used particularly in XRF applications. An X-ray generator also needs to contain a cooling system to cool the anode; many X-ray generators use water or oil recirculating systems.
