Reconstruction of multislice tomographic images from four-dimensional data

摘要

The invention provides tomographic image generation from four-dimensional projection data of an imaged object. The ability is provided to extract implicit information from time dependent aspects of volumetric projection data corresponding to multiple data acquisition cycles. The result is improved volumetric image quality from volumetric projection data previously used for slice by slice image reconstruction. The invention provides particular advantages for volumetric imaging of a patient's heart, or a portion thereof, at a selected phase of the cardiac cycle.
