Scoliosis Slicer Extension

BenChurch edited this page Oct 2, 2017 · 1 revision

The Slicer extension, currently named PostureAssessmentToolkit, used for scoliosis assessment with ultrasound methods, is described on this page.

Overview

PostureAssessmentToolkit is being developed to provide clinicians with a means of quantifying and classifying postural attributes such as the Cobb angle, plumb-line deviations, or scoliosis classifications. The extension is intended to use various forms of ultrasound data for assessment.

Modules

UsSurfaceToLandmarks

This module can use ultrasound scans of the spine, saved as an mha file, loaded into Slicer as a volume, to generate the transverse process landmark point data used in the extension's other modules.

PreProcessLandmarks

This module has functionality to both repair omitted landmarks, and artificially degrade landmark sets (for repair functionality development, for example).

StandardizeLandmarks

This module allows the standardization of landmark sets by centering and normalizing (mapping to range [-1,1]) their coordinates. Most importantly for this extension, it provides a method for extrapolting landmark sets to include points for all vertebrae from T1 to L5. The assessment module currently requires omission-free landmark sets spanning the entire thoracic and lumbar spines to operate.

AssessLandmarks

This module takes a complete transverse process landmark set as input and returns the various metrics computed for assessment as well as methods for visualizing the patient's spine and postural aspects.
