Abstract
According to an aspect, there is provided a computer implemented method of processing an image of a subject comprising lymph nodes, the method comprising: segmenting lymph nodes in image data corresponding to the image, delineating lymph nodes from the segmented image data, classifying a lymph node as belonging to a predefined region, evaluating a region of the image based on an assessment of the risk of the region comprising a malign lymph node, and indicating the evaluation of the region.
Claims19
A computer implemented method of processing an image of a subject comprising lymph nodes, the method comprising:
- receiving lymph nodes delineated from segmented image data;
- classifying at least one of the lymph nodes as belonging to an anatomical nodal region;
- evaluating a region of the image based on an assessment of the risk of the anatomical nodal region comprising a malign lymph node;
- and
- indicating the evaluation of the region.
A method of training a machine learning model for use in processing an image of a subject comprising lymph nodes, the method comprising:
- obtaining training data, the training data comprising an image of a subject with at least one annotation of a lymph node, and the risk of the lymph node being malign or a set of rules for assessing whether a lymph node is malign, and an annotation indicating at least one anatomical nodal region;
- and
- training the model based on the training data to evaluate a region of the image based on an assessment of the risk of the anatomical nodal region comprising a malign lymph node.
A system for processing an image of a subject comprising lymph nodes, the system comprising:
- a memory comprising instruction data representing a set of instructions;
- and
- a processor configured to communicate with the memory and to execute the set of instructions, wherein the set of instructions, when executed by the processor, cause the processor to:
- receive lymph nodes delineated from segmented image data;
- classify at least one of the lymph nodes as belonging to an anatomical nodal region,
- evaluate a region of the image based on an assessment of the risk of the anatomical nodal region comprising a malign lymph node, and
- indicate the evaluation of the anatomical nodal region.
