Fig. 8. —Bar chart shows application of postprocessing options averaged for all observers and patients. Note that in just over half of cases observers applied both options, and only in few cases (1K: 8%, 2K: 13%) did observers not apply postprocessing. For all 48 patients, application frequency of window setting and magnification was investigated for all observers. Student's t test did not indicate statistically significant differences in use of window setting (p = 0.14) and magnification (p = 0.24) between 1K and 2K monitors. Light shading = 1K monitor with postprocessing. Dark shading = 2K monitor with postprocessing.
