Visualization of anatomical data by augmented reality

摘要

A sensor means is employed to sense a distance to the surface of a subject to be examined, so that a range image may be acquired. Intensity information may be acquired alongside the distance information. The distance information and intensity information may be evaluated to track the pose of the sensor means relative to the surface of the subject to be examined, so that anatomical data related to said subject may be displayed as seen from the position and/or orientation of the sensor means or display means. By moving the sensor means or display means along the surface of the subject to be examined, such as a patient in a hospital environment, the user hence gets the impression of being able to look directly into the human body.

主权项

1. A system for visualizing anatomical data, comprising:
a display means; a sensor means adapted to sense a distance of said sensor means to at least a part of a surface of a subject to be examined; a position tracking means adapted to determine a position and/or an orientation of said sensor means and/or said display means relative to said surface of said subject by evaluating distance information provided by said sensor means; and a visualization means adapted to visualize on said display means information generated from anatomical data relating to said subject; wherein said visualization means is adapted to visualize said information generated from said anatomical data on said display means in accordance with said position and/or orientation of said sensor means and/or said display means; and wherein said position tracking means simulates a plurality of range images based on said anatomical data, and compares said simulated range images against an acquired range image generated from said distance information to identify a simulated range image best corresponding to said acquired range image.
