Publikováno v: Medical Imaging: Image Perception, Observer Performance, and Technology Assessment
The channelized-Hotelling observer (CHO) was investigated on the ability to predict the human detection performance in order to assess clinical image quality objectively. CHO applied three user-selectable difference of Gaussian (DoG) channels on the

Publikováno v: Medical Imaging: Image Perception, Observer Performance, and Technology Assessment
We investigate whether humans need to be shown the entire image stack (3D) or only the central slice (2D) of the lesion of breast tomosynthesis images in signal-known-exactly detection experiments. A directional small-scale breast tissue model based
