Abstract
A system and method for associating anatomically significant regions with regions of one or more images may include automatically modifying images of different modalities according to different correction algorithms, providing a user interface for identifying a plane within three-dimensional data, scaling atlas structures to fit an anatomical image according to identified landmarks, registering an atlas to such an image via a combination of registration algorithms, and/or registering an atlas to such an image using a feature extraction algorithm.
Claims10
A system for associating anatomical information with image data that forms a three-dimensional space, the system comprising:
- a computer processor configured to:
- output a graphical user interface (GUI) in which a first two-dimensional image slice of the image data and a second two-dimensional image slice of the image data are simultaneously displayed, wherein the first and second two-dimensional image slices are orthogonal to each other;
- obtain, via user interaction with the GUI, selection of three points within the three-dimensional space, two of the three points being selected in different respective ones of the first and second two-dimensional image slices, wherein a first point of the three points corresponds to an anterior commissure (AC) and a second point of the three points corresponds to a posterior commissure (PC);
- record the three points in association with the image data;
- selecting an alignment point along a line connecting the AC to the PC;
- aligning the image data with an anatomical atlas by anisotropically scaling the image data using a first scaling factor in an anterior/posterior direction relative to the alignment point and a second scaling factor in a superior/inferior direction relative to the alignment point, wherein the first and second scaling factors are different.
