Prior image based three dimensional imaging

摘要

Described herein are technologies for facilitating three-dimensional imaging based on prior image data. In accordance with one aspect, deformable registration is performed to align three-dimensional (3D) image data to a sparse set of two-dimensional (2D) projection image data of at least one structure of interest. An iterative reconstruction scheme may then be performed to minimize a difference between the aligned 3D image data and the 2D image data.

1. An imaging system comprising:
a memory device for storing computer readable program code; and a processor in communication with the memory device, the processor being operative with the computer readable program code to:
receive prior three-dimensional (3D) image data and a sparse set of two-dimensional (2D) projection image data of at least one structure of interest, wherein the sparse set of 2D image data is acquired after the 3D image data is acquired;perform a deformable registration to align the 3D image data with the 2D image data; andminimize a difference between the aligned 3D image data and the 2D image data by performing an iterative reconstruction scheme.
