(PSF) insert in the SedentexCT IQ phantom (SedentexCT IQ, Leeds Test Objects Ltd., Boroughbridge, UK) was used to calculate the MTF. The PSF insert is made of a stainless steel wire (diameter: 0.25 mm) suspended in the air. In or-der to identify the optimal method of MTF measurement, factors affecting the MTF were investigated using a 3-step
