Computed Tomography Technologist

The computed tomography technologist operates specialized radiographic equipment and processes data to create cross-sectional images of the human body. These images are used to assess and diagnose medical conditions.

CT technology is a highly sophisticated x-ray procedure that uses computer programs to create pictures of organs, bones, soft tissue and blood vessels. Each picture, or slice, shows different aspects of your body in a two-dimensional image (like slices of bread) or a three-dimensional image (like a loaf of bread).

Computed tomography scans are fast and painless. They can help detect internal injuries and bleeding and save lives.

The CT scan process begins when you lie on a special table that slides into the center of the CT scanner. The machine’s x-ray beam rotates around you, while the computer creates many separate images of your body, or “slices,” which can be stored, viewed on a monitor, printed on film or transferred to electronic media.

In some cases, your doctor may ask you to drink a special contrast solution before the CT scan, which helps certain areas of your body show up better on the x-rays. Depending on the type of test, you may also be given an injection of a contrast agent through a vein in your arm or mouth.

Computed Tomography Medical Definition

Computed Tomography (CT) is a type of medical imaging that uses special X-ray equipment to create detailed pictures of areas inside the body. The term “tomography” comes from Greek words tomos (a cut, a slice, or section) and graphein (to write or record).

CT scanners use a narrow beam of X-rays that penetrate the body to different depths depending on the density of the tissues being studied. A computer then combines the images to create a cross-sectional image of a patient’s internal structures.

A CT scan is a painless, noninvasive procedure that can help doctors diagnose and treat various conditions. It can also help detect abnormal masses that may be malignant tumors.

Computed tomography scans are used by physicians and care teams in hospitals, clinics and outpatient facilities to help determine the root cause of disease. They are used to diagnose and monitor diseases and injuries such as strokes, head injuries, abdominal problems and internal bleeding.

Computed Axial Tomography

Computed axial tomography, or CT for short, is a form of X-ray imaging that produces detailed 3D images of your body’s interior. This procedure uses a large tube with rotating detectors that collect the energy of a beam of ionizing radiation to produce high-resolution images. It is a safe, painless and noninvasive way to see your internal organs without compromising your dignity. The best part is that the technology is highly accurate and yields detailed information about any size or shape of body part. It is also the smartest and most cost-effective method to determine the exact location of a tumor or other medical malady.

In a nutshell, the most important component of this technological marvel is a powerful computer that processes and stores data from the multiple detectors. This is achieved through a series of algorithms that are constantly analyzing data and producing high-resolution images. These are then displayed for review by the technologist. The biggest challenge is to keep the patient calm and compliant while he or she is inside the machine.

Computed tomography is a diagnostic imaging technology that creates high-quality 3D images of internal organs and structures. It’s an important tool in the detection of cancer and other diseases, and is also used to evaluate injuries and determine how well a patient is responding to treatment plans.

CT uses specialized ionizing radiation to take pictures of cross-sectional areas inside the body, like the brain, spine, teeth, abdomen/pelvis, chest, and more. It can be used to detect fractures, blood clots and other issues with bones that aren’t visible on an X-ray.

A computed tomography technologist works with radiologists and a patient’s care team to perform CT scans on patients. They use their knowledge of anatomy, physiology and pathology to efficiently operate the scanners while also providing compassionate communication during a procedure.

Many colleges and universities offer a CT certificate program to prepare radiologic technologists, nuclear medicine technologists or radiation therapists for a career as a computed tomography professional. These programs are one or two semesters long and provide coursework related to the operation of a CT scanner. They usually include clinical practicums where students are paired with local clinical partners.

X-ray Computed Tomography

X-ray computed tomography is an imaging technique that uses a computer to generate a series of detailed pictures of areas within the body. It can be used to diagnose disease or identify abnormalities. A dye may be injected into a vein or swallowed to help the organs and tissues show up more clearly.

CT scans can be done on various sections of the body, including the head, abdominal area, thoracic (chest) and lumbar spine. They can also be used to examine blood vessels and tumors.

A radiologist interprets the results of a CT scan and can make recommendations about treatment. CT can be used to identify cancers, heart disease, infectious diseases, trauma and musculoskeletal disorders.

X-ray CT uses a spiral or helical X-ray machine and computer to create cross-sectional images of the body. The images are then reconstructed in multiple planes and can be used to generate 3D images. The computer system also can calculate the size and location of a tumor. It is often the best method of detecting cancers since it allows the doctor to see the full extent of the tumor and determine its size.
