Major components of the CT scanner include?

• A. X-ray Tube, Detector Array, Control Panel
• B. Patient Table, Pillow, Shielding
• C. Display Monitor, Keyboard, Mouse
• D. Gantry, Computer, Operating Console

Answer: (D)

In CT imaging, the major components are the gantry, the computer, and the operating console. The gantry is the rotating frame that houses the X-ray tube and the detector array; it revolves around the patient to collect projection data from many angles, which is what makes cross-sectional imaging possible. The computer takes that raw data and reconstructs it into cross‑sectional images using specialized algorithms, processing and enhancing the images for diagnostic use. The operating console is where the technologist controls the scan—setting parameters like tube voltage and current, rotation time, slice thickness, and protocol selection, and where images are viewed and adjusted during or after acquisition. Other items like the patient table, pillow, and shielding are important for positioning and safety but are supplementary to the scanner’s imaging core. Display monitors, keyboards, and mice belong to the workstation used for interpretation and control, but they are not the primary imaging system components.
