X Ray Image Filter. Therefore the places with more contrast agent show lower gray value in an x ray angiogram image as shown in fig. The total filtration of the beam includes the inherent filtration composed of part of the x ray tube and tube housing and the added filtration thin sheets of a metal inserted in the x ray beam.
Filters are metal sheets placed in the x ray beam between the window and the patient that are used to attenuate the low energy soft x ray photons from the spectrum filtering is the removal of these low energy x rays from the beam spectrum which would otherwise not contribute to image quality but would add to patient dose and scatter. 1 a illustrates that the places with contrast agent absorb more x ray than the places without contrast agent in heart. For medical purposes x ray filters are used to selectively attenuate or block out low energy rays during x ray imaging radiography.
