Abstract

The invention discloses an X-ray-assisted puncture positioning method and system. The method includes: acquiring a 3D scanned picture group of a puncture object target scan area and displaying the 3D scanned picture group; dividing to obtain an outline of a puncture object according to the 3D scanned picture group; receiving a target spot that a tip of a puncture needle needs to arrive at, and displaying the target spot in the 3D scanned picture group; receiving current needle length of the puncture needle, and determining and displaying a current body surface puncture area on the outline according to the current needle length and the target spot; receiving at least one surface puncture point selected in the current body surface puncture area, and for each surface puncture point, determining and displaying a puncture path according to the surface puncture point and the target spot. The X-ray-assisted puncture positioning method and system according to the technical scheme has the advantages that puncture positioning efficiency can be improved.

Description

technical field

[0001] The invention relates to an X-ray-assisted puncture positioning method and system. Background technique

[0002] X-ray interventional technology is a technology that uses X-ray devices, such as X-ray tomography (CT) machines or C-arm-X-ray machines, as guiding devices to guide puncture needle biopsy or treatment. It is under the guidance of X-ray devices, Through a small wound or a human cavity, a specific device is introduced into the diseased part of the human body through a puncture needle for treatment.

[0003] When performing X-ray interventional therapy, it is best to accurately insert the puncture needle into the target position without injuring other important tissues and organs during the puncture. In the current puncture process, usually after the puncture object is in a good position, firstly find the target position to be reached by the puncture needle under the guidance of X-rays in different directions, and then locate the puncture poin...
