Figure Lengend Snippet: Technical specifications of x-ray systems used for specimen margin analysis during BCS in published studies. 37 – 41 The imaging areas, spatial resolution all dramatically affect the imaging time, and so comparisons on all three of these issues is challenging. But in general imaging full specimens on a timescale near a minute or less is possible for both x-ray and micro-CT with spatial resolution near 10 to 20 μ m .
