WebThe modulation transfer function (MTF) of the system is calculated based on a theoretical model using a novel approach, which uses an analytical expression for absorbed dose. It is found that if appropriate materials are used for the conversion layer, then the intrinsic MTF of the high QE flat panel is better than that of current EPIDs, and in addition they have a … WebAt 33 keV and for the 40 (100) microm screen, at 10% the MTF is 9.2 (8.6) line-pairs mm(-1). The NNPS was found to be different in the two analyzed directions in relation to frequency.

WebIn fact, the intrinsic MTF of the new camera is rather close to unity in the spatial frequency range up to 1 line pair per centimeter (1p/cm). Further improvement would require a fundamentally new approach to gamma imaging, free of the limitations of conventional collimators (e.g., coded-aperture imaging techniques).
