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. A non-transitory computer readable medium embodying a program of instructions executable by machine to perform steps for facilitating three-dimensional imaging implemented by a computer system, the steps comprising:
receiving prior three-dimensional (3D) image data of vasculature; intraoperatively acquiring a sparse set of two-dimensional (2D) projection image data of the vasculature, wherein the sparse set of 2D image data is acquired after the 3D image data is acquired; performing a deformable registration to align the 3D image data with the 2D image data; and minimizing a difference between the aligned 3D image data and the 2D image data by performing an iterative reconstruction scheme.
