Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues ().Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. A Computed Tomography (CT) Scan uses X-rays and a sophisticated computer to view specific parts of the anatomy in great detail. CT scans are sometimes referred to as CAT scans or computed tomography scans. CT/CAT scans are also being used to screen for lung cancer, he explained. A computed tomography (CT) scan can create cross-sectional images of any part of your body using special X-rays and a computer. Computer Tomography (CT) CT or ‘CAT’ scans are a form of X-ray that creates a 3D picture for diagnosis. This type of scan takes a series of x-rays and uses a computer to put them together. Also called CAT scans, computed tomography (CT) scans take X-rays and filter them through computerized technology to create a 3-D view of the patient’s organs. All imaging studies including X-Ray, Ultrasound, CT and MRI use the DICOM protocol . It is a painless, noninvasive, and common imaging exam. Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. Besides the medical field, CT scans are also used in archeology and other fields. The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record). Types of PET Scans. CT Angiography, or CTA, is a type of contrasted CT scan used to evaluate the blood vessels. The scan can show cross-sectional images of a specific area of the body. Contrast dye is usually injected into the body before the scan … CT scans are typically more expensive than x-rays and aren’t always readily available at rural or small hospitals. This radioactive tracer is chosen based on which area of the body is under investigation. CT (CAT) scanning—is a noninvasive medical test that helps physicians diagnose and treat medical conditions.- combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body.- Basics of CT Scan 2. A CT scan has many uses, but it's particularly well-suited to quickly examine people who may have internal injuries from car accidents or other types of trauma. In this article, we will outline the basic science behind CT scans, describe the principles of interpretation, and highlight their advantages and drawbacks compared to other imaging techniques. Some of the most common types of diagnostic imaging tests are magnetic resonance imaging tests, (MRIs), and Computed Tomography (CT) scans. A CT scan is typically used for: bone fractures The computed tomography (CT) scan is a medical imaging procedure that uses x-rays and digital computer technology to create detailed two- or three-dimensional images of the body. Bone densitometry is a type of imaging examination that measures your bone mineral density, which is a sign of bone strength. Two types of CT scans include: 1. MRI There are essentially two types of CT scans: Conventional CT scan - the scan is taken slice by slice and after each slice the scan stops and moves down to the next slice - eg, from the top of the abdomen down to the pelvis. This type of radiology study is an important part of diagnosing medical diseases like strokes, cancers, and infections in the abdomen like appendicitis. This requires patients to hold their breath to avoid movement artefact. A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body. Certain types of brain scans use a special dye, called contrast, to help areas of interest show up better. CT scans are sometimes called CAT scans. A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as … Unlike other forms of medical imaging, the CT scan can make an image of every type of body structure at once, including bone, blood vessels and soft tissue. What is Current Transformer (CT) ? A CT (computed tomography) scan, also called a CAT scan, is a type of specialized X-ray. The PET CT scan helps the physician to see the level of activity of certain body … Current transformers (CT) are used in High Voltage (HV) and Medium Voltage (MV) [1] installations to give an image of electrical current to protection relays and units and metering equipment and they are designed to provide a current in its secondary proportional to the current flowing in its primary. A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body.

Mammography is a type of X-ray scan of the breast. CT scans can also be used for fluid or tissue biopsies, or as part of preparation for surgery or treatment. The most common scans for diagnosis and follow-up are magnetic resonance imaging (MRI) and computerized tomography (CT). Those who perform CT scans are either radiologic technologists or radiographers. "A CT scan is sort of our workhorse of radiology," Dr. Herron said.
