Image annotation using a haptic plane

摘要

During an analysis technique, a three-dimensional (3D) image of a portion of an individual is transformed to facilitate accurate determination of detailed annotation of an anatomical structure (such as: specifying the size of the anatomical structure based on annotation markers, an orientation of the anatomical structure, a direction of the anatomical structure and/or a location of the anatomical structure). In particular, in response to receiving information specifying a two-dimensional (2D) plane having an angular position in the 3D image, the 3D image is translated and rotated from an initial position and orientation so that the 2D plane is presented in an orientation parallel to a reference 2D plane of a display. Then, after information specifying the detailed annotation in the 2D plane is received, the 3D image is translated and rotated back to the initial position and orientation.

主权项

1. A computer-implemented method for facilitating detailed annotation of an anatomical structure, the method comprising:
providing, on a display, a three-dimensional (3D) image of a portion of an individual, wherein the 3D image has an initial position and orientation; receiving information specifying a two-dimensional (2D) plane in the 3D image, wherein the 2D plane has an arbitrary angular position relative to the initial orientation; using the computer, translating and rotating the 3D image so that the 2D plane is presented in a reference 2D plane of the display with an orientation parallel to an orientation of the reference 2D plane, wherein, prior to the translating and the rotating, the angular position is different than that of the reference 2D plane and is different from a predefined orientation of slices in the 3D image; receiving information specifying the detailed annotation in the 2D plane, wherein the detailed annotation includes at least one of: a size of the anatomical structure based on annotation markers, an orientation of the anatomical structure, a direction of the anatomical structure and a location of the anatomical structure; and after the annotation is complete, translating and rotating the 3D image back to the initial position and orientation.
