1. An imaging device comprising:
a radiation detector array arranged to acquire imaging data;
a computer; and
a non-transitory storage medium storing instructions readable and executable by the computer to perform an image reconstruction method including:
performing iterative image reconstruction of the acquired imaging data to generate a reconstructed image; and
during the iterative image reconstruction, applying an edge preserving prior having a spatially varying edge preservation threshold, wherein a value of the edge preservation threshold at each image voxel depends on a noise metric in a local neighborhood of the image voxel.
