• Operate X-ray machines to capture images of bones, organs, and tissues.
• Utilize CT scanners to create cross-sectional images of the body for detailed analysis.
• Conduct fluoroscopy exams to visualize real-time images of internal organs during procedures.

2. Patient Positioning and Care

Radiation Technicians work closely with patients to position them correctly for examinations. They provide clear instructions and ensure patient comfort while ensuring proper exposure to radiation. They also monitor patients during procedures and promptly respond to any discomfort or adverse reactions.

• Position patients accurately for precise image acquisition.
• Provide clear instructions and reassurance to patients throughout the examination.
• Monitor patients during procedures and provide immediate assistance as needed.

3. Image Processing and Analysis

Radiation Technicians are responsible for processing and analyzing the images obtained from radiation equipment. They use specialized software to enhance and interpret images, providing valuable information to physicians for diagnosis and treatment planning.

• Process and enhance raw images to improve diagnostic quality.
• Identify and analyze abnormalities or areas of interest in the images.
• Collaborate with physicians to interpret images and provide insights for patient care.

4. Radiation Safety and Compliance
