GPU-BASED SYSTEM FOR PERFORMING 2D-3D DEFORMABLE REGISTRATION OF A BODY ORGAN USING MULTIPLE 2D FLUOROSCOPIC VIEWS

摘要

Systems and methods for assisting a physician in a medical intervention comprises performing a 2D-3D deformable registration, and more particularly, performing a 2D-3D registration based on multiple live 2D fluoroscopic views, and implemented on a multi-core processing framework such as a Graphics Processing Unit.

1. A computer-implemented method for assisting a physician in a medical intervention on a patient comprising:
receiving 3D image data of a body organ of the patient prior to the medical intervention; receiving multiple 2D views of the body organ; and performing, on a multi-core processing framework, multiple parallel computations including a cost function value and a gradient vector to determine a deformable registration on the 3D image data based on the receiving multiple 2D views wherein the multi-core processing framework computes a 3D deformation field.
