Computed Tomography Certificate

The Computed Tomography certificate program provides imaging professionals with the foundational education necessary to advance into various career possibilities, including advanced imaging modalities, graduate degrees, and professional advancement into entry management, education, and informatics positions with an emphasis in Computed Tomography (CT).

What Is a CT Scan?

A computed tomography (CT or CAT) scan allows doctors to see inside your body. It uses a combination of X-rays and a computer to create pictures of your organs, bones, and other tissues. It shows more detail than a regular X-ray.

How Do CT Scans Work?

They use a narrow X-ray beam that circles around one part of your body. This provides a series of images from many different angles. A computer uses this information to create a cross-sectional picture. Like one piece in a loaf of bread, this two-dimensional (2D) scan shows a “slice” of the inside of your body.

This process is repeated to produce a number of slices. The computer stacks these scans one on top of the other to create a detailed image of your organs, bones, or blood vessels. For example, a surgeon may use this type of scan to look at all sides of a tumor to prepare for an operation.

How Are CT Scans Done?

A radiology technologist will perform the CT scan. During the test, you’ll lie on a table inside a large, doughnut-shaped CT machine. As the table slowly moves through the scanner, the X-rays rotate around your body. It’s normal to hear a whirring or buzzing noise. Movement can blur the image, so you’ll be asked to stay very still. You may need to hold your breath at times.

What Is It Used For?

  • Doctors order CT scans for a long list of reasons:
  • CT scans can detect bone and joint problems, like complex bone fractures and tumors.
  • If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes.
  • They show internal injuries and bleeding, such as those caused by a car accident.
  • They can help locate a tumor, blood clot, excess fluid, or infection.
  • Doctors use them to guide treatment plans and procedures, such as biopsies, surgeries, and radiation therapy.
  • Doctors can compare CT scans to find out if certain treatments are working. For example, scans of a tumor over time can show whether it’s responding to chemotherapy or radiation.
