Brainlab SE Atlas Trajectory Planning Method
Summary
USPTO granted Patent US12605214B2 to Brainlab SE for a computer-implemented method of planning straight trajectories in medical images. The method divides an atlas into first and second areas during image registration, restricting transformation of the first area to maintain straight trajectory geometry while allowing unrestricted transformation of second areas. The patent contains 14 claims and covers CPC classifications in diagnostic imaging and medical image processing.
What changed
USPTO issued Patent US12605214B2 to Brainlab SE on April 21, 2026, covering a computer-implemented method for planning straight trajectories in medical images of anatomical structures. The method involves registering an atlas template with a medical image, dividing the atlas into a first area containing the trajectory and second areas without trajectory content, and applying differential transformations where the first area transformation is restricted to maintain straight geometry while second areas allow unrestricted image registration.
Competitors developing medical image navigation or surgical planning software should review this patent to assess freedom-to-operate implications for similar atlas-based registration techniques. The patent's 14 claims cover both the method and associated image processing classifications in the A61B diagnostic and G06T image processing domains.

Abstract
Disclosed is a computer-implemented method of planning a straight trajectory in a medical image of an anatomical structure. A template of the straight trajectory is given in an atlas and the atlas is registered with the medical image. The atlas is divided into a first area and one or more second areas, wherein the first area comprises the straight trajectory and the one or more second areas do not comprise any part of the straight trajectory. When the transformation of the atlas onto the medical image is calculated, the first and second areas are treated differently. The transformation of the first area maintains the straight shape of the trajectory and is thus restricted. The transformation of the one or more second areas is unrestricted and thus allows any kind of image registration. The template of the transformed atlas is the applied to the medical image.
