We predict human observer performance for lesion detection on breast cone beam computed tomography (CBCT) images using single-slice and multislice model observers with a constant internal noise level. We evaluate human observer performance on single-slice and multislice simulated breast CBCT images with 1 mm signal, and predict the performance using model observers. We use a channelized Hotelling observer (CHO) and nonprewhitening observer with eye-filter (NPWE). We employ dense difference-of-Gaussian (D-DOG) channels for CHO, and eyefilter with peak value at 7 cyc/deg for NPWE. We include channel internal noise for CHO and decision variable internal noise for NPWE. For single-slice images, D-DOG CHO and NPWE predict human observer performance well. For multislice images, D-DOG CHO overestimates human observer performance, while NPWE predict human observer performance successfully.
