Roles and Responsibilities

Patient care

CT Technologists are responsible for providing patient care during the imaging process. This includes explaining the procedure to the patient, addressing any concerns or questions, and ensuring the patient’s comfort throughout the examination. They must also obtain a patient’s medical history and follow any necessary precautions for patients with specific medical conditions or implants.

Positioning patients

CT Technologists need to position patients accurately to obtain the required diagnostic images. They must consider factors such as patient comfort, image quality, and radiation dose while positioning the patient and adjusting the CT scanner.

Operating CT equipment

CT Technologists must have a thorough understanding of CT scanners, including how to set the appropriate exposure parameters and align the equipment to obtain the necessary images. They must also follow radiation safety protocols to minimize the patient’s exposure to ionizing radiation.

Image quality control

CT Technologists are responsible for evaluating the quality of the CT images they produce. They must ensure the images are of diagnostic quality and make any necessary adjustments to the equipment or patient positioning if required.

Post-processing and reconstruction

CT Technologists may be responsible for post-processing and reconstructing the CT images using specialized software. This can involve creating multiplanar reconstructions, 3D images, or advanced visualization techniques to aid in diagnosis and treatment planning.

Collaborating with physicians

CT Technologists work closely with radiologists and other physicians to ensure that the required diagnostic images are obtained. They may discuss the images with the radiologist or provide additional information about the patient’s medical history or the examination.

Maintaining patient records

CT Technologists must keep accurate patient records, including documentation of the examination, patient history, and any relevant findings or concerns.

Equipment maintenance and quality assurance

CT Technologists are responsible for performing routine maintenance and quality assurance checks on their CT equipment. This includes ensuring that the equipment is functioning correctly and adhering to any relevant safety standards or regulations.

Work Environment

CT Technologists work in various healthcare settings, including hospitals, outpatient clinics, imaging centers, and private practices. They work closely with radiologists, other healthcare professionals, and patients of all ages.
