The typical imaging chain is a specialize X-ray tube with an IR that we call _____ that can be viewed during exposure.
Fluoroscopic Screen
It is the main Modality in the Radiologist and to Radtechs and other staffs performing under Interventional Radiology because it involves active diagnosis during the exam.
Imaging Chain
The Fluoroscopic Tube are designed to operate in _____ period at _____ mA.
Imaging Chain:

lower
_____ is the application of materials and methods to create, preserve and duplicate images. The _____ is a multi-disciplinary field that is concern with the generation, collection, duplication, analysis, modification and visualization of images including imaging things that can human eyes cannot detect.
Imaging chain
Imaging science
_____ is a process by which one image is formed and interprets, and it can be also be conceptualize as a chain of physical events.
