What are the different types of medical imaging devices?

There are a number of different types of medical imaging devices that help diagnose diseases and injuries. For example, X -ray and computer tomography (CT) are useful for evaluating broken bones and searching for certain types of cancer. Nuclear imaging can also detect cancer as well as infections and injuries. Other common types of medical imaging devices include ultrasonic and magnetic resonance imaging (MRI).

One of the most common types of medical imaging devices is the X -ray scanner. X -ray imaging works by firing high -energy electromagnetic waves on the body. These are absorbed by dense structures in the body such as bones but pass through less dense areas. X -ray imaging allows the physician to assess the bony structure of the body, which is particularly useful in checking bone fractures. X -rays can also be effective in checking certain types of cancer such as breast cancer.Puter is used to take pictures from different anglesat. The patient lies on the table and the scanner moves around the body and sends X -rays from different sides of the body. This allows the doctor to assess parts of the body that are not usually accessible with a regular X -ray image.

For evaluating certain types of cancer and infections, nuclear scanning is often used. A radioactive substance is injected into the body, which can be detected by specially designed cameras. The scanner then detects where the substance is, resulting in an image. This type of display is considered safe because the dose of radioactive material is very small.

Another common form of medical imaging device is ultrasound. Ultrasound is a higher frequency than the human range of hearing and reflects the substance based on its density. This allows ultrasonic medical imaging device to detect the difference between the bmezi by liquid and the solid areas of the body, resulting in an image of the internal structure. The benefits of ultrasoundKovo equipment includes that technology is small enough to transmit and ultrasound is generally harmless.

MRI works differently from X -rays because it does not use high -energy electromagnetic waves. Instead, the MRI machine can detect changes in the magnetic rotation of atoms in the body. A strong magnetic field is applied to the body, while the computer reads data from the machine and forms a detailed picture. MRI machines are able to provide high -resolution images, but cannot be used for people with any form of metal implant.
