  • Page 7 Chapter 1 Introduction The PaxScan 4336R model family of radiographic digital image receptors is commonly referred to as a flat panel detector (FPD). The detector together with image processing and command software called Virtual Command Processor (VCP) is designed for integration into a complete X-ray system. The imaging system has two main system components: The 38.3 x 42.7cm 139µm-pixel amorphous silicon FPD that houses the solid-...
