How a C-Arm System Works
A C-arm is an imaging system with a curved support structure that allows the X-ray source and detector to move around the patient.
X-Ray Generator and Tube
The generator supplies the electrical conditions required for X-ray production. The X-ray tube produces the radiation used to create images.
Image Detector
The detector captures the X-ray signal after it passes through the patient. Depending on the system, the detector may use an image intensifier or a flat-panel design.
Mechanical C-Arm Structure
The C-arm structure supports movement and positioning of the X-ray source and detector. Smooth, controlled movement is important for clinical workflow and safe positioning.
Workstation and Image Processing
The workstation manages image acquisition, display, processing, and storage.
Controls and Safety Systems
System controls and safety mechanisms support operation and help prevent unsafe movement or exposure. These features must not be bypassed.
