Computed tomography

What is computed tomography? Computed tomography (CT) is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is sometimes called computerized tomography or computerized axial tomography (CAT) Computed tomography (CT) imaging provides a form of imaging known as cross-sectional imaging. CT imaging produces cross-sectional images of anatomy Computed tomography angiography (CTA) is a type of contrast CT to visualize the arteries and veins throughout the body. This ranges from arteries serving the brain to those bringing blood to the lungs, kidneys, arms and legs. An example of this type of exam is CT pulmonary angiogram (CTPA) used to diagnose pulmonary embolism (PE) Computed tomography. Computed tomography (CT) is an imaging modality that utilizes x-ray photons for image production, with digital reconstruction. The CT scanner essentially consists of an x-ray tube and detectors. The x-ray tube produces an x-ray beam that passes through the patient Computed tomography (CT) is the imaging technique that creates two-dimensional cross-sectional images from three-dimensional body structures. To obtain image, CT uses a mathematical technique called reconstruction

Computed tomography (CT) is a well-established diagnostic imaging modality that has been in clinical use in medicine for several decades but only recently has become commonly used in veterinary medicine. The essential concept of a CT scanner is that an x-ray-generating tube is positioned across from a row of digital x-ray detectors in a circular gantry Computed tomography. Computed tomography (CT) scanning, also known as, especially in the older literature and textbooks, computerised axial tomography (CAT) scanning, is a diagnostic imaging procedure that uses x -rays to build cross-sectional images (slices) of the body  Computed Tomography is a well accepted imaging modality for evaluation of the entire body.  Computed Tomography(CT) Scan Machines Uses X- rays, a powerful form of Electromagnetic Radiation Computed tomography (CT) was created in the early 1970s to overcome many of these limitations . By acquiring multiple x-ray views of an object and performing mathematical operations on digital data, a full 2D section of the object can be reconstructed with exquisite detail of the anatomy present

Since computed tomography (CT) has entered the industrial environment around thirty year ago, an increasing interest for this technology was shown especially in the non-destructive testing, thanks to its advantages in comparison with traditional destructive techniques. The development of powerful systems with more stable X-ray sources an A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body. CT scans are sometimes referred to as CAT scans or computed tomography scans. They're carried out in hospital by specially trained operators called radiographers, and can be done while you're staying in hospital or during a short visit Computed tomography (CT), also called computerized tomographic imaging or computerized axial tomography (CAT), diagnostic imaging method using a low-dose beam of X-ray s that crosses the body in a single plane at many different angles

X-ray Computed Tomography (CT) is a nondestructive technique for visualizing interior features within solid objects, and for obtaining digital information on their 3-D geometries and properties. A CT image is typically called a slice, as it corresponds to what the object being scanned would look like if it were sliced open along a plane FIGURE 16-5 Spiral Computed Tomography. As the patient moves smoothly through the gantry aperture (along the Z axis), the tube and detectors continuously travel around the patient, creating a spiral path. The other major development in CT technology is multislice computed tomography (MSCT) used in conjunction with spiral imaging (Figure 16-6) Computed tomography (CT) was created in the early 1970s to overcome many of these limitations ().By acquiring multiple x-ray views of an object and performing mathematical operations on digital data, a full 2D section of the object can be reconstructed with exquisite detail of the anatomy present ().During the years since its invention, CT technology has undergone continual improvement in. Computed tomography (CT), developed in the 1970s by William Oldendorf and Godfrey Hounsfield, is an X-ray technique that allows for the visualization of 3- to 10-mm (approximately 0.12- to 0.4-inch) sections of the brain, skull, and spinal column (as well as other part

Introduction • Computed tomography (CT) is a medical imaging method employing tomography. • A large series of two-dimensional X-ray images (slices) of the inside of an object are taken around a single axis of rotation. • Digital geometry processing is used to generate three-dimensional images of the object from those slices Computed tomography — an increasing source of radiation exposure. (in the case of a multislice ct scanner, which will be discussed in chapter 10, the number of measurements in a single projection can easily be quadrupled.

Image Reconstruction Techniques. Image reconstruction in CT is a mathematical process that generates tomographic images from X-ray projection data acquired at many different angles around the patient. Image reconstruction has fundamental impacts on image quality and therefore on radiation dose. For a given radiation dose it is desirable to. Computed tomography definition is - radiography in which a three-dimensional image of a body structure is constructed by computer from a series of plane cross-sectional images made along an axis —called also computed axial tomography, computerized axial tomography, computerized tomography Computed tomography is the largest source of medical radiation exposure. The benefits of computed tomography are immense and certainly exceed the risks. However, this is only true when they are ordered appropriately and studies are optimized to obtain the best image quality with the lowest radiation dose
