Computed Tomography Technologists use specialized equipment to scan a patients body to create detailed images of the internal organs and structures for medical diagnosis. This is done by using x-ray imaging in a rotating camera which creates cross-sectional scans of the body. The result is a detailed, three-dimensional view of the patients body, allowing medical professionals to diagnose medical conditions such as cancer, fractures, clots, and other diseases.

The effect of a Computed Tomography Technologist is invaluable in the healthcare industry, as they are able to provide accurate images that help doctors make more informed decisions and provide better care for their patients. Furthermore, this profession requires strong technical and interpersonal skills, along with an in-depth knowledge of anatomy, physiology, radiologic physics and radiation safety. Computed Tomography Technologists must also be certified in order to practice in the United States, demonstrating their proficiency and dedication to the field.

Steps How to Become

Obtain a High School Diploma or GED. To become a computed tomography (CT) technologist, the first step is to have a high school diploma or GED.
Earn an Associate Degree in Radiologic Technology. Most employers require CT technologists to have a two-year associate degree in radiologic technology from an accredited college or university. These programs typically include courses in anatomy, physiology, radiation physics, patient care and medical terminology.
Complete a CT Training Program. After earning a degree, prospective CT technologists must complete an approved training program in computed tomography. These programs typically involve classroom instruction and hands-on clinical experience in a healthcare facility.
Earn Certification. After completing a training program, future CT technologists must take and pass an exam administered by the American Registry of Radiologic Technologists (ARRT). This certification is required for CT technologists to practice in most states.
Obtain Licensure. Some states also require that CT technologists obtain licensure in order to practice. Requirements vary by state but generally involve passing an exam and continuing education classes.

The use of computed tomography (CT) technologist is essential for obtaining accurate medical imaging results. To ensure ideal and efficient performance, it is necessary to properly train CT technologists on the most current technological advancements and adhere to the highest standards of safety protocols. the technologist should be aware of the various contrast media options available and understand how to properly administer them.

Furthermore, CT technologists must be knowledgeable in the techniques and principles of radiation safety and protection. Finally, it is important to be aware of the latest CT equipment and techniques, in order to provide the best quality images and maximize efficiency. By following these guidelines, CT technologists can provide the most ideal and efficient results.

Computed Tomography (CT) Technologists are highly skilled healthcare professionals who specialize in using imaging technologies to diagnose and treat medical conditions. The most important skill a CT technologist must possess is the ability to accurately interpret and analyze the images produced by the CT scan machine. This requires a strong understanding of anatomy and physiology, as well as a familiarity with the image manipulation software used by the CT scanner.

in order to accurately assess the patients condition, the technologist must be able to effectively communicate with other physicians and radiologists. Furthermore, the technologist must be knowledgeable about radiation safety protocols and take appropriate safety measures to ensure that patients are not exposed to excessive radiation during the scanning process. All of these skills are essential for CT technologists to successfully perform their job duties and provide quality patient care.
