Depending on the size of the test sample the filament should generate enough radiation to penetrate the material and sometimes when the materials are so large the energy also becomes enormous. Anode; to convert electronic energy into radiation and to dissipate heat. Instant access to millions of ebooks, audiobooks, magazines, podcasts and more. At these frame rates, the human visual system cannot distinguish frame-to-frame variation and motion appears to be continuous, without visible flicker. But here is the thing, the size of the X-ray beam generated and projected by the Cathode is dependent on the focal spot size set by the technologist operating the machine. 600 0 obj<> 287fabfb-1f31-44fa-908e-7f665369b421.pdf Introducing Cram Folders! endobj Learn faster and smarter from top experts, Download to take your learnings offline and on the go. Most High Frequency generators reduce patient exposure by 50% or more when compared to Standard Frequency generators while quality films with consistent density and contrast. Likewise, the heat is further intensified when the radiation from the filament hits the rotating Anode disc sometimes reaching extreme levels of heat. 606 0 obj<> Grids may be circular (XRII systems) or rectangular (FPD systems) and are often removable by the operator.
