What is tomography?
tomography is a branch of display that creates a picture called Tomogram, which shows the only plane of the object in a very specific detail. Many people think that tomography in terms of medical imaging, which is used to create a cross -section of the body to reveal basic health conditions. Other disciplines of science also use tomography, including biology, geology, oceanography, archeology and material science. This technique has been used since the mid -twentieth century, although the technology for the production of tomograms is constantly improving. In a field like archeology, it ensures that the integrity of specimens is retained with respect when they are studied. In medicine, tomography is less invasive than reconnaissance surgery and can provide an excellent idea of what is happening inside a patient for medical providers. Geologists use it to look at the cross-countryrock and other material and the technique even appears in some high-tech criminal laboratories so the evidence can be analyzed without destroyedand.
Mathematics for tomography is quite complex. Basically, the beams are browsing through the object that appears, and the rays or tomographic machine move during the imaging process to blur additional aircraft and pull one cross -section into a sharp detail. Usually the sample is kept calm and maintaining is still an important direction in medical display to ensure sharp images. Unfortunately, for patients, medical devices can be used to create tomographic images very noisy and cramped, so the direction that still has very unpleasant.
in tomography is used a number of different beams, including X -rays, gamma beams, ultrasound, magnetic resonance and more. Once the images of the object have been obtained, they go through the program, which cleans the images and creates a clear cross -section. Some computer reconstruction programs can also create three -dimensional oBraz an object that can be manipulated to get more information about its internal functioning.
As with other imaging techniques that bombard energy objects, tomography can be dangerous. People who regularly perform tomographic imaging are usually protected by standing behind a barrier or wearing a special gear that is designed to resist harmful radiation. In patients, a certain amount of lifelong exposure is somewhat inevitable, but becomes a problem when the patient is exposed to repeated diagnostic imaging in an effort to get to the bottom of the health problem.
