MATLAB codes for ACR phantom QA, work in progress
Tests are:
- geometry accuracy (geom.m, done)
- high contrast spatial resolution (spatial_res.m)
- slice thickness accuracy (slice_th.m)
- slice position accuracy (slice_pos.m)
- image intensity uniformity (iiu_psg.m)
- percentage signal ghosting (iiu_psg.m)
- low contrast object detectability (lcod.m)
otsu.m is used for binary segmentation
