Real-time stepping type percutaneous puncture planning system

Abstract

The invention relates to a real-time stepping type percutaneous puncture planning system. The system comprises a needle inserting starting point determining module used for determining a needle inserting starting point on an initial planning image according to a CT value of the initial planning image, a path planning module used for planning a puncture path by taking the needle inserting starting point as a starting point and a target point as an end point, and setting N staged planned needle inserting points on the puncture path through the CT value, a real-time three-dimensional image registration module used for carrying out image scanning when puncturing to the i-th staged planned needle inserting point, and registering obtained image sequence data with data of the initial planning image, and a risk assessment module used for obtaining error data according to the registered data so as to judge whether a real puncture needle is on a needle inserting path of the puncture path or not and whether a real target spot deviates or not. The dynamic safety range in the puncture operation implementation process can be given.

Description

technical field [0001] The invention relates to the technical field of computer-aided medical treatment, in particular to a real-time step-by-step percutaneous puncture planning system. Background technique [0002] Percutaneous puncture technology is mainly used for tumor sampling biopsy or tumor ablation surgery that requires percutaneous puncture insertion. Usually, prior to the operation, pre-operation planning is required. In the existing technology, the target point where the lesion is located is simulated on the 3D model of the human abdomen in advance, and the puncture needle enters the 3D model of the human abdomen through the needle-accessible area on the body surface. , dangerous area, and then simulate a feasible percutaneous puncture path that can bypass the above-mentioned dangerous area. At present, the optimal percutaneous puncture path can be selected from multiple feasible percutaneous puncture paths through computer programs, but due to errors in the punct...

Usually, prior to the operation, pre-operation planning is required. In the existing technology, the target point where the lesion is located is simulated on the 3D model of the human abdomen in advance, and the puncture needle enters the 3D model of the human abdomen through the needle-accessible area on the body surface. , dangerous area, and then simulate a feasible percutaneous puncture path that can bypass the above-mentioned dangerous area. At present, the optimal percutaneous puncture path can be selected from multiple feasible percutaneous puncture paths through computer programs, but due to errors in the puncture process However, it is still possible to enter the dangerous area, so an intraoperative planning system is urgently needed to solve this problem
