A C-arm fluoroscope is a mobile imaging device that provides real-time X-ray images during procedures. It is called a C-arm because the X-ray source and image detector are mounted on a C-shaped arm. The design lets the imaging beam move around the patient without moving the patient as much. C-arm fluoroscopes are used by trained teams in operating rooms, procedure suites, and interventional settings.

It may be used in orthopedic surgery, pain procedures, vascular access, urology, cardiology, gastroenterology, trauma care, and interventional radiology. The images help confirm position and movement during treatment. The benefit of imaging is balanced with radiation exposure management.
The X-ray tube emits a beam that passes through the patient to an image detector. The system converts the X-ray pattern into live images displayed on a monitor. The C-arm can rotate or tilt to show different angles. Pulsed fluoroscopy, collimation, dose settings, and image storage features help support imaging while limiting unnecessary exposure.
A C-arm fluoroscope includes an X-ray tube, image receptor or flat-panel detector, C-shaped arm, control panel, monitor cart, generator, foot pedal or hand controls, brakes, and positioning handles. Some systems include dose displays, image capture, roadmapping, or digital subtraction features. Mini C-arms are smaller systems used for selected extremity imaging. The device must be positioned and checked before imaging begins.
C-arm fluoroscopy uses ionizing radiation, so staff follow radiation safety practices. Time, distance, shielding, collimation, low-dose settings, and proper positioning help reduce exposure. Lead aprons, thyroid shields, glasses, barriers, and dosimeters may be used depending on the setting. Skin injury, high cumulative dose, pregnancy concerns, or equipment alarms should be managed according to radiation safety policy.
No. A regular X-ray usually captures still images, while a C-arm fluoroscope can provide live moving X-ray images during a procedure.
Yes. It uses ionizing radiation, so dose reduction and shielding practices are important.
It may be operated by trained radiology technologists, surgeons, physicians, or procedural staff depending on the facility and procedure.
Yes. The C-shaped arm can rotate and angle around the patient to capture different views during a procedure.
