Segmentation Using Skeletally Coupled Deformable Models

Based on "Segmentation of carpal bones from CT images using skeletally coupled deformable models” by Thomas B. Sebastian, Hüseyin Tek,

Joseph J. Crisco, Benjamin B. Kimia

The Problem: Wrist Difficulties

• Poorly understood kinematics• Many small bones hinder traditional methods• Static images cannot always diagnose problem

Proposed Solution: Diagnosis in Motion

• Potential to detect problems in soft tissue by observing motion of bones

• Segment bones through modified region growing

Sebastian et al.

Technical Implementation

• Global “skeleton” of image• Predict boundaries → Control growth speed• Region competition• Allow for back-and-forth

Sebastian et al.

Project Timeline

• Weeks 1-2– Obtain Data– Revive code

• Mid-Project Presentation– Preliminary Results

• Weeks 3-4– Finish code revival if necessary– Run algorithm – Write report/presentation
