Abstract
A method and a system for image-guided intervention such as a percutaneous treatment or diagnosis of a patient may include at least one of a pre-registration method and a re-registration method. The pre-registration method is configured to permit for an efficient virtual representation of a planned trajectory to target tissue during the intervention, for example, as a holographic light ray shown through an augmented reality system. In turn, this allows the operator to align a physical instrument such as a medical probe for the intervention. The re-registration method is configured to adjust for inaccuracy in the virtual representation generated by the pre-registration method, as determined by live imaging of the patient during the intervention. The re-registration method may employ the use of intersectional contour lines to define the target tissue as viewed through the augmented reality system, which permits for an unobstructed view of the target tissue for the intervention.
