Abstract
A method for analyzing a shape of a region of interest in a medical image of a body part, including: finding a region of interest in the medical image; calculating a Reeb graph of the region of interest, and determining whether the region of interest is a malignant lesion candidate based on a shape characteristic of the Reeb graph.
Claims19
A method for analyzing a shape of a region of interest in a medical image of a body part, comprising:
- collecting, by a scanner, the medical image of the body part;
- finding, by a processor, a region of interest in the medical image;
- calculating, by the processor, a Reeb graph of the region of interest;
- and
- determining, by the processor, whether the region of interest is a malignant lesion candidate based on a shape characteristic of the Reeb graph.
A system for analyzing a shape of a region of interest in a medical image of a body part, comprising:
- a memory device for storing a program;
- a processor in communication with the memory device, the processor operative with the program to:
- find a region of interest in the medical image;
- calculate a Reeb graph of the region of interest;
- and
- determine whether the region of interest is a malignant lesion candidate based on a shape characteristic of the Reeb graph.
A method for analyzing a shape of a region of interest in a medical image of a body part, comprising:
- collecting, by a scanner, the medical image of the body part;
- finding, by a processor, a region of interest in the medical image;
- calculating, by processor, an isolation measure for each voxel in the region of interest;
- and
- determining, by the processor, whether the region of interest is a malignant lesion candidate by using the isolation measures.
