"United States Patent 8,194,820 Optimal weights for measuring spectral x-ray data" We have developed a novel method for fast image simulation of flat panel detectors, based on the photon energy deposition efficiency and the optical spread function (OSF).
Flat panel detectors (FPDs) are used to obtain high resolution computed tomography (CT) image.
Borasi, G; Samei, E; Bertolini, M; Nitrosi, A; Tassoni, D, Contrast-detail analysis of three flat panel detectors for digital radiography., Medical Physics, vol 33 no.
The development of flat panel detectors and cone beam CT also allows real-time imaging and capability for three-dimensional reformations with lower radiation doses than CT [20, 21, 22].
In high resolution computed tomography (CT) using flat panel detectors, imperfect or defected detector elements cause stripe artifacts in sinogram which results in concentric ring artifacts in the image.
To overcome the limitations of both medical scanners and of the systems based on flat panel detectors, in the framework of the neu_ART regional project [10], we developed a versatile CT system based on a linear detector moved by a high precision mechanics allowing us to obtain a radiograph up to 3.5 m wide and 0.5 m high in few tenths of seconds.
