A method of scanning a part comprises setting software scanning parameters of a scanning apparatus to produce an image. Setting the software scanning parameters includes setting an output voltage to a maximum output value, for example 450 kV and setting an output current and a magnification so that a power/voxel ratio of the scanning apparatus is in a range of between 2 and 3, for instance, between 2.25 and 2.75. The method further comprises scanning the part.

Systems and methods for improving radiographic scanning. In an example, the technology relates to a system for performing radiographic scanning. The system includes a photon source configured to emit photons. The system also includes a photon counting detector for detecting photons emitted from the photon source after passing through a target. The photon counting detector comprising first pixels having a first size and second pixels having a second size, and the first size is greater than the second size.

One embodiment is a method for binning charge events in a photon-counting CT scanning system comprising a plurality of discriminators, wherein each discriminator is associated with a respective one of a plurality of threshold voltage levels, the method comprising detecting a transition in a signal output from one of the discriminators; and incrementing a count corresponding to the threshold voltage level associated with the one of the discriminators only if the detected discriminator output signal transition was immediately preceded by an opposite transition in the discriminator output signal.
