Abstract
An image processing apparatus for reconstructing a tomographic image from a plurality of projection images acquires noise data for a plurality of projection images, respectively, acquires noise reconstruction data by executing reconstruction processing based on the acquired noise data, and reconstructs the tomographic image by executing the reconstruction processing based on the projection images and the noise reconstruction data.
Claims11
