Accuracy system

A system configured to determine an accuracy of a stereotactic frame comprising translatable components configured to position a pointer tip at a real-space target in an x-y-z coordinate system, wherein the system is configured to:

• define the x-y-z coordinate system;
• define an x displacement from a target point of a phantom base mechanically engaging the stereotactic frame to the pointer tip of the stereotactic frame when the pointer tip is placed at a pointer tip location, wherein the x displacement is a distance parallel to an x axis in the x-y-z coordinate system, and wherein the target point defines the real-space target;
• define a y displacement from the target point to the pointer tip when the pointer tip is placed in the pointer tip location, wherein the y displacement is a distance parallel to a y axis in the x-y-z coordinate system;
• define a z displacement from the target point to the pointer tip when the pointer tip is placed in the pointer tip location, wherein the z displacement is a distance parallel to a z axis in the x-y-z coordinate system, wherein the system is configured to at least one:
• define at least one of the x displacement or the y displacement on a horizontal anatomical plane defined by an intercranial space of a patient, and define the z displacement on at least one of a medial anatomical plane defined by the intercranial space or a coronal anatomical plane defined by the intercranial space of the patient;
• or
• define one of the x displacement or the y displacement substantially parallel to an anterior or posterior direction of the patient and define the other of the x displacement or the y displacement substantially parallel to a left lateral or a right lateral direction of the patient and define the z displacement substantially parallel to a superior or inferior direction of the patient, wherein the x displacement, the y displacement, and the z displacement defines the accuracy of the positioning of the pointer tip at the real-space target by the stereotactic frame;
• and
• map the x-y-z coordinate system to a coordinate system defined by the phantom base;
• and
• provide an output viewable by a practitioner, wherein the output indicates one or more of the x displacement, the y displacement, or the z displacement mapped to the coordinate system defined by the phantom base.

A method, comprising:

• defining, with a system, an x displacement from a target point of a phantom base mechanically engaging a stereotactic frame to a pointer tip of the stereotactic frame when the pointer tip is placed at a pointer tip location in proximity to the target point, wherein the x displacement is a distance parallel to an x axis in an x-y-z coordinate system, the stereotactic frame comprising translatable components configured to position the pointer tip at a real-space target in the x-y-z coordinate system, wherein the target point defines the real-space target;
• defining, with the system, a y displacement from the target point to the pointer tip when the pointer tip is placed in the pointer tip location, wherein the y displacement is a distance parallel to a y axis in the x-y-z coordinate system;
• defining, with the system, a z displacement from the target point to the pointer tip when the pointer tip is placed in the pointer tip location, wherein the z displacement is a distance parallel to a z axis in the x-y-z coordinate system;
• and
• providing, with the system, an output viewable by a practitioner, wherein the output indicates one or more of the x displacement, the y displacement, or the z displacement to determine the accuracy of the positioning of the pointer tip at the real-space target by the stereotactic frame.
