Embodiment Construction

[0120] A general context for the above method is a method of planning the introduction of a needle in a patient coupled to a needle guide tracked by a navigation system relative to a 3D medical image of the patient.

[0121] like Figure 8 As shown, the method is implemented by a system comprising a computer comprising a processor 8 adapted to be coupled to a navigation system 7 to receive navigation data, and a display 9 coupled to the processor 8, and the display 9 is configured to display in 3D medical A representation of the virtual needle and a representation of the relative position of the virtual needle with respect to the at least one detected needle is displayed in the image.

[0122] Needles in a 3D image can be detected using known image processing algorithms that detect line segments from a set of highlighted voxels arranged linearly in a large number of voxels.

[0123]Advantageously, a needle guide can be placed on the inserted needle to facilitate its detection...

Abstract

The invention relates to a method for planning the introduction of a needle in a patient's body, wherein the needle (2) is coupled to a needle guide (3) tracked by a navigation system with respect to a 3D medical image (1) of the patient, comprising: - determining a virtual position and orientation of the needle (2) with respect to the 3D image (1) using navigation data of the needle guide (3); - detecting at least one inserted needle (2'; 2a', 2b', 2c') as a trace in the 3D medical image (1); - displaying a representation of the virtual needle (2) and a representation of a relative position of the virtual needle with respect to the at least one detected needle (2'; 2a', 2b', 2c').

Description

technical field [0001] The present invention relates to a system for planning the introduction of a needle in a patient. Background technique [0002] Surgical procedures performed in interventional radiology involve the introduction of one or more surgical instruments, such as needles or equivalents, into a patient. [0003] Interventional radiologists use an imaging system, most likely computed tomography (CT scan) or cone beam computed tomography (CBCT) or magnetic resonance imaging (MRI), to look at a patient's organs and select them for tip (tip). ) and the trajectory followed by the needle to reach that target. [0004] To help interventional radiologists reach this target, a navigation system is necessary. Such systems use tracking systems based on optical technology, electromagnetic technology, radio frequency technology, inertial technology, ultrasonic technology or mechanical technology. [0005] The purpose of the tracking system is to provide the real-time spa...
