What are the different types of diagnostic imaging devices?
Some of the most commonly used types of diagnostic imaging devices include X -ray machines, computer tomography (CT) scanners, magnetic resonance (MRI) scanners, positron emissions (PET) scanners and ultrasonic machines. Each of these pieces of diagnostic imaging equipment allows health care providers to study different internal body structures. Although each part of the equipment is similar, it performs a different function that helps professionals in diagnosis and treatment.
X -ray machines operate by sending a small amount of radiation in the form of electromagnetic waves, through the body to a film or a special album. Electromagnetic waves are usually absorbed by bones, thick tissues and any metal objects in the body and pass through soft tissues such as skin, muscle and fat. When the film or album developed into an X -ray film, all areas where electromagnetic waves from the X -ray machine were absorbed. The areas of whom went through to the movie or albums to lookblack. X -rays are often used to diagnose bone problems such as fractures or dental cavities, and to identify foreign objects in the body such as bullets or nails.
CT scanners are a special type of X -ray machine. In general, the CT scanners include a large ring that emits electromagnetic waves and captures those that pass through the body. The scanner is associated with a computer that helps interpret X -ray images and usually shows them as cross -sectional or two -dimensional views of the X -ray parts of the body. CT scanners generally capture details than X -ray machines, so they can be used to display bones, organs, tumors and other tissues in the body.
Another type of diagnostic imaging device is MRI scanner. Unlike X -ray machines and CT scanners, the MRI scanner does not use radiation; Intead, uses magnetic and radio waves. MRI scanner usually contains a large magnet in tboiling of the cylinder with a hole in the middle into which the patient slips. This magnet creates a magnetic field that surrounds the patient when he enters the scanner. Generally, radio waves go through regular intervals, creating data that is transmitted to a connected computer that converts data into cross -sectional images of organs, blood vessels and bones.
pets for pets are another type of diagnostic imaging device that uses a ring into which the patient slips. In this case, the ring detects a radioactive material that the patient usually swallows, inhales or receives intravenous injections immediately before scanning PET. The patient then usually lies on the table and slips into a pet-glass circle, where the detectors monitor radioactive material when it moves through the body. The ring is connected to a computer that uses information about how much radioactive material is absorbed to create a picture of what occurs inside the body. In general they can be a skeNerly for pets used to find out how certain organs such as heart and brain, and body functions such as blood flow,
The final common type of diagnostic imaging device is an ultrasonic machine. Ultrasonic machines usually consist of several components, including a converter monitor, computer and videos. The converter sends a high -frequency sound wave body and then listens to the echoes. This information is translated by a computer into an image that usually appears on the video monitor. Ultrasonic machines are often used to view soft tissues such as organs and blood vessels, and can be seen inside the uterus during pregnancy to monitor the development of the fetus.
