Differences in a maximum and b mean activity concentration for each kV relative to 120 kV reference in NEMA IQ phantom. Data points also corresponding to ‘CARE kV on’ shown with blue markers. There are 6 data points per kV setting corresponding to VOIs over the 6 spheres with some data points overlapping, particularly at 0.00% difference in measured activity concentration
