This study presents a cost-effective method using public domain software to process 3D volumetric data from ovine spinal peripheral quantitative computed tomography (PQCT) scans, enabling detailed bone macro-architecture analysis for fusion assessment.

Area of Science:

  • Biomedical imaging
  • Quantitative analysis
  • Surgical research

Background:

  • Commercial medical imaging software can be costly and inflexible for research.
  • Developing adaptable image processing methods is crucial for specialized research needs.

Purpose of the Study:

  • To create a method for processing and acquiring 3D volumetric data from ovine spinal PQCT scans.
  • To utilize public domain software for image manipulation and analysis.

Main Methods:

  • Processed 32 DICOM PQCT scans of ovine spines post-fusion.
  • Employed image processing, masking, and segmentation to remove surgical hardware.
  • Calculated normalized bone macro-architecture volumes in specific spinal segments.

Main Results:
