What are the different types of devices for nuclear medicine?
The
nuclear medicine device uses advanced nuclear technologies for diagnostic medical imaging and disease treatment. Different types of nuclear medicine devices are designed for use in conjunction with specific radioisotopes for different imaging purposes. Specialized sensors act as cameras to detect and monitor radiation emitted by a small amount of radioisotopes or radionuclides in medical dyes. Radiography has been based on X -ray equipment for decades before progress in technology has enabled the development of various highly sophisticated nuclear imaging methods. The imaging device for nuclear medicine allows much earlier detection of health problems because these images are able to demonstrate changes in metabolic functioning along with structure changes.
Specialized nuclear medical equipment is used for nuclear scintigraphy - diagnostic imaging of bones and soft tissue. A scintigraphic camera or gamma camera detects gamma -emitted radionuclides. RAdionuclides are comzahaled drugs to create radiopharmaceuticals, formulated to focus on specific organs or bone tissue. Nuclear scintigraphy detects metabolic abnormalities because patients or injured tissues accumulate radiopharmaceutics other than normal tissue, which provides diagnostic images determining health problems. The computer converts data collected by a gamma camera into images.
Computer tomography (SPECT) uses a gamma camera that turns around a particular body of focused radiopharmaceuticals. This nuclear medical equipment is used in combination with a gamma emitter that has a relatively long half -life to show how blood flows into tissues and organs. Rather than being absorbed into tissues and organs, radiopharmaceutics remain in the bloodstream. Sophisticated computer programs transform data collected by a gamma camera into images. Computer ridgeDA two -dimensional cross -sections into a three -dimensional image of the studied body.
Positron emission tomography (PET) also creates a three -dimensional image of tissues or organs in the body. Radiopharmaceutics concentrate on scanning tissue or organ, causing a pair of gamma photons. The detection device converts emissions to light and then into electrical signals that turn into computer images. The table on which the patient is on is moving and the process repeats and creates a number of images. The particle accelerators are produced by radioisotopes with very short half lives for use in PET scanning, so this nuclear medical equipment must be located near the accelerator.
Zumalka also uses nuclear medicine equipment. The health of teeth, jaws and tissues is analyzed using dental X -ray images. These images are produced by an X -ray and captured on a film or an electronic sensor located in the patient's Moutth. A panoramic view of the whole mouth to useá externally placed film or sensors. The use of computer tomography scanning (CT) for dental display expands with progress in the area of nuclear medicine.
Veterinary science uses nuclear medicine equipment made specifically for animals. A specially designed small animal and agricultural animal are available for imaging purposes. Large animal CT scanners are built to suit animals weighing up to a ton. Nuclear scintigraphy is also used in animals to detect bone and ligament injuries or to evaluate the functioning of the brain, liver or other organs. As in human patients, gamma and injected radioisotopes are used to view bones and internal organs.
