Q. Why are there different foil thicknesses for your QA Test Patterns ?
A. Our test patterns are offered in different foil thicknesses as different applications are more suited to a certain thickness of lead.
0.1mm foils are typical for fluoroscopy
0.05mm are typical for digital imaging
Thinner foils e.g. 0.02 and 0.03mm are typical for mammography (usually when a higher spatial frequency is necessary e.g. 20LP/mm – can’t be manufactured in thicker lead)
However, please note that this is just a rough guide and the choice of test pattern depends on the specific application and customer preference.
