The receptor head is the system that converts the X-ray beam into a visible image and allows it to be displayed. Modern systems accomplish this by using either an image intensifier (II) or a flat-panel detector (FPD). Both allow real-time fluoroscopy, as well as last-image hold, image storage and retrieval, and other features to assist in procedures or reduce radiation dose. This chapter covers the design and functions of image receptor heads used on C-arm systems that produce images from the incident X-ray beam. This includes the process of intensification and amplification of the image within an II system, as well as the function and the use of newer FPD systems.
