Abstract
System and method for automatically extracting at least one region of a first type of bone tissue from a target bone. A digital radiograph image with the target bone is received. Based on the digital radiograph image, at least one region of a first type of bone tissue is automatically identified or extracted. This region can then be utilized for different purposes, such as assessment, qualitative assessment, quantitative assessment, analysis, spatial domain analysis, frequency domain analysis, and calculation of one or more target bone features.
Claims17
A method for automatically extracting at least one region of a first type of bone tissue from a target bone comprising the steps of:
- receiving a digital radiograph image with the target bone;
- and
- automatically identifying at least one region of a first type of bone tissue based on the digital radiograph image;
- wherein automatically identifying at least one region of a first type of bone tissue based on the digital radiograph image further comprises
- automatically generating at least one region of trabecular bone tissue;
- wherein automatically generating at least one region of trabecular bone tissue further comprises
- generating an intermediate region of trabecular bone tissue based on one of a left contour and right contour, a center axis, and at least one anchor point;
- and
- generating a final region of trabecular bone tissue based on the intermediate region of trabecular bone tissue.
A system for automatically generating at least one feature of a target bone comprising:
- an automatic bone tissue region extractor for automatically extracting at least one region of a first type of bone tissue from the target bone based on a digital radiograph image automatically identifying at least one region of a first type of bone tissue;
- wherein the automatic bone tissue region extractor includes a trabecular bone tissue determination mechanism for automatically extracting at least one region of trabecular bone tissue;
- wherein the automatic bone tissue region extractor generates an intermediate region of trabecular bone tissue based on one of a left contour and right contour, a center axis, and at least one anchor point;
- and
- generates a final region of trabecular bone tissue based on the intermediate region of trabecular bone tissue;
- and
- a feature mechanism for generating at least one feature of the target bone based on the extracted region of first type of bone tissue.
