How do I turn my spiral acquisition protocol into an axial protocol with the correct slice thickness (CT number calibration and slice thickness images, Film page 1, Boxes 4 – 12; Module 1)?
In multi-detector-row CT (MDCT), the reconstructed slice thickness is not always the same as the Tomographic thickness of one data channel (T as defined in the ACR accreditation documents). For a given helical acquisition protocol, the user must determine the corresponding values of N and T, as defined in the accreditation documents (see FAQ number 1). The reconstructed image thickness is often not the same as the underlying detector collimation (T).
