Method and magnetic resonance system to automatically determine imaging planes

摘要

In a method and imaging apparatus to automatically determine imaging planes for an imaging procedure to visualize a percutaneous intervention of a patient along a trajectory to a target point, data are obtained that represent a reference coordinate system with three orthogonal reference planes, and data also are acquired that represent the trajectory. One of the reference planes is determined as a selected reference plane based on the arrangement thereof relative to the trajectory. A first imaging plane is defined such that the trajectory lies therein, and such that it has a defined arrangement in relation to the selected reference plane. A second imaging plane is defined such that the trajectory lies therein, and such that it is orthogonal to the first imaging plane. A third imaging plane is defined such that it is orthogonal to the first imaging plane and second imaging plane, and includes the target point.

1. A computerized method to automatically determine imaging planes in an imaging procedure to visualize a percutaneous intervention of a patient whom an instrument proceeds along a trajectory within the patient from a starting point to a target point within the patient while the patient is situated in an imaging apparatus, said method comprising:
providing reference coordinate system data to a processor that represent a reference coordinate system of the patient, said reference coordinate system data defining three orthogonal reference planes of said reference coordinate system; providing said processor with trajectory data representing the spatial arrangement of said trajectory and said target point, said trajectory having a defined spatial arrangement between said starting point and said target point in relation to said reference planes; in said processor, automatically selecting one of said reference planes as a selected reference plane based on the arrangement of the reference planes relative to the trajectory; in said processor, defining a first imaging plane such that said trajectory lies in said first imaging plane, and such that said first imaging plane has a defined spatial arrangement in relation to the selected reference plane; in said processor, defining a second imaging plane such that the trajectory also lies in said second imaging plane and such that said second imaging plane is orthogonal to said first imaging plane; in said processor, defining a third imaging plane such that said third imaging plane is orthogonal to said first imaging plane and is orthogonal to said second imaging plane, and such that said third imaging plane comprises said target point; and from said processor, generating and emitting an electrical signal in a format to operate said imaging apparatus in order to acquire image data from the patient in said first, second and third imaging planes, said image data comprising data that visually represent said trajectory between said starting point and said target point.
