1. A computer-implemented method for detecting a microcalcification cluster in reconstructed volumes of a three-dimensional digital breast tomosynthesis image, comprising: receiving, at a computing device, a three-dimensional digital breast tomosynthesis image; reconstructing, at the computing device, the three-dimensional digital breast tomosynthesis image; enhancing, at the computing device, a microcalcification candidate in each slice of the three-dimensional digital breast tomosynthesis image; detecting, at the computing device, a seed object in the enhanced three-dimensional digital breast tomosynthesis image; and detecting, at the computing device, potential individual microcalcifications in the vicinity of the seed object that form a microcalcification cluster.
