Abstract

An apparatus according to an embodiment includes a memory and processing circuitry. The processing circuitry receives an image, the image comprising voxels arrayed in three spatial dimensions, acquires from the memory a first network and a second network, denoises the received image using the first network and the second network to produce a denoised output image. Each of the first network and the second network comprises weighting coefficients of connections between neuronal nodes of respective layers of a plurality of layers between an input layer and an output layer of a neural network. The first network is adapted to receive first two-dimensional (2D) slices of an image provided at its input layer, the first 2D slices being perpendicular to a first direction. The second network is adapted to receive second two-dimensional (2D) slices of an image provided at its input layer, the second 2D slices being perpendicular to a second direction, which is a different direction than the first direction.
