Abstract:
Aiming at the problem of inaccurate imaging model of three-dimensional (3D) reconstruction of rotational digital subtraction angiography (DSA), a nonlinear model based on object-oriented quantization is introduced first. The model quantizes the projection pixel of 3D vessel slice as the number of vessels which the X-ray goes through. Furthermore, a slice reconstruction algorithm named segment self-guide reconstruction (SSGR) is developed. The SSGR is especially suitable for solving the problem of sparse projection and limited-views. Finally, the simulated results have proved the feasibility of the model and the validity of the algorithm.
