Abstract
A system and method can increase confidence or other factors of a tract identified in a selected image data. The system can use various confidence determining factors to identify confidence in the identified tract. The identified tract can be used for various purposes, such as diagnosis or treatment.
Claims23
A system to determine a confidence of an anatomical structure in a displayed image data of an anatomy, comprising:
- a processor system configured to execute instructions for:
- accessing a gradient image data of the anatomy;
- determining a diffusion of matter in the anatomy based on the gradient image data of the anatomy including formulating a tensor of the diffusion;
- determining a first estimate of an anatomical structure in the accessed gradient image data based at least in part on a selected first criterion;
- determining a second estimate of the anatomical structure in the accessed gradient image data based at least in part on a selected second criterion that is different than the first selected criterion;
- comparing the first estimate of the anatomical structure and the second estimate of the anatomical structure;
- determining a difference between the first estimate of the anatomical structure and the second estimate of the anatomical structure;
- determining a confidence in at least one of the first estimate of the anatomical structure or the second estimate of the anatomical structure based at least in part on the determined difference between the first estimate of the anatomical structure and the second estimate of the anatomical structure;
- and
- determining a configuration of the anatomical structure based at least on the determined confidence.

A system to determine a confidence of an anatomical structure in a displayed image data of an anatomy, comprising:
- a display device configured to display an image of the anatomy;
- and
- a processor system configured to execute instructions to:
- determine a first estimate of an anatomical structure based at least on a first seed point in an image data of the anatomy;
- determine a second estimate of the anatomical structure based at least on a second seed point in an image data of the anatomy, wherein the second seed point is spaced apart from the first seed point;
- compare at least one of a medial axis, a shape, a branching, or a distance to a structure of the first estimate of the anatomical structure to the same at least one of a medial axis, a shape, a branching, or a distance to a structure of the second estimate of the anatomical structure;
- and
- determine a confidence in at least one of the first estimate of the anatomical structure or the second estimated of the anatomical structure based at least in part on a determined difference between the first estimate of the anatomical structure and the second estimate of the anatomical structure based on the comparison.

A system to determine a confidence of an anatomical structure in a displayed image data of an anatomy, comprising:
- a processor system configured to execute instructions to:
- determine a first fiber tract estimate of a fiber tract based at least on a first seed point in a diffusion data set of the anatomy,
- determine a perturbation criteria for a second tract estimate of the fiber tract in the diffusion data set of the anatomy,
- determine the second tract estimate of the fiber tract based at least on the determined perturbation criteria,
- compare the first tract estimate of the fiber tract and the second tract estimate of the fiber tract, and
- determine a confidence in at least one of the first tract estimate of the fiber tract or the second tract estimate of the fiber tract based at least in part on a determined difference between the first estimate of the fiber tract and the second estimate of the fiber tract;
- and
- a display device configured to display a confidence visualization of at least one of the first tract estimate or the second tract estimate based on the determined confidence.
