Figure 2From: A method of extending the depth of focus of the high-resolution X-ray imaging system employing optical lens and scintillator: a phantom study Imaging model of high-resolution X-ray imaging system in which the thickness of the employed scintillator is not matching with the objective lens. D: Object distance, F: Image plane distance, d: Diameter of lens aperture, f: Focal length, CoC: Circle of Confusion, A(x,y,z):Object point, B(x',y',z'):virtual imaging point.Back to article page
