X-ray machine using a photon is emitted through the body. Very dense structures such as bone, making the photon is not able to pass through so it will appear white.
On the results of the scan, in addition to bone white, air will appear black, while fluid, fat, and muscle will be grayed out.
X-ray machines are used widely in the field of health. X-ray images produced called radiography.
Here are the different types of X-ray machine:
1. CT Scanner
CT (computed tomography) scanners are commonly used in the health field. CT scans take a two-dimensional scanning which is then processed into digital radiography.
CT scan machine resembles a large box with a hole in the middle as well as a table. When scanning, the patient lies on a table and then moves into the hole to be scanned. Scanned and then computer processed to produce 2D radiographs.
2. Bone X-ray machine
Bone X-ray machine consists of an X-ray tube is accompanied by an examination table. Under examination table are X-ray film and tape recorders.
X-ray tube is attached to a flexible robotic arm that can be moved depending on the body part being scanned.
Tube then emits photons that pass through the body. This machine emits low levels of radiation are not harmful to the patient. Bone X-ray machines are also available in small portable version.
3. linear Accelerator
Machines used for radiotherapy linear accelerator. This machine emits radiation to kill the cancer without affecting other parts of the body.
This machine emits strong X-ray to be able to kill cancer cells. This machine is easily calibrated to suit a variety of different patient conditions.
4. Backscatter X-ray
Backscatter X-ray machines used for airport security and passenger baggage checking. This machine can see through clothing and other materials so as to detect the contents of the trunk.
Backscatter X-ray machine uses a different technology than traditional X-ray machine. Instead of measuring the intensity of photons that pass through an object, this machine measures the ability of objects to deploy proton.
Materials such as liquids and metals will absorb more photons. The computer will measure the level of deployment that then produces an image.
The X-ray machine produces images faster and easier, and provides sharp detail, much better than conventional X-ray machine.
