Software programs available that perform measurements!
Surgimap
Surgimap is a widely used, spine-specific radiographic analysis and surgical planning software designed for evaluation of spinal alignment and deformity. It enables standardized measurement of coronal and sagittal parameters, including: Cobb angles, sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), and segmental alignment; primarily from standing radiographs. Surgimap is extensively cited in the spine literature and has become a de facto reference standard for deformity assessment, preoperative planning, and postoperative outcome evaluation. Its intuitive interface and free availability have contributed to broad adoption among spine surgeons, trainees, and researchers worldwide.
SOLA Spine
SOLA Spine is an educational, web-based platform focused on improving understanding of spinal alignment and spinopelvic parameters through clear visual explanations and structured teaching modules. Rather than functioning as a DICOM-based measurement or surgical planning tool, SOLA Spine serves as a conceptual and educational resource that explains key sagittal and coronal alignment principles, such as sagittal balance, pelvic incidence, pelvic tilt, lumbar lordosis, and global alignment relationships, using simplified diagrams and clinician-friendly language. The platform is particularly valuable for trainees, educators, and clinicians seeking to reinforce foundational alignment concepts, standardize terminology, and improve interpretability of radiographic measurements generated by dedicated software platforms. SOLA Spine complements formal measurement tools by strengthening the cognitive framework required to correctly interpret and apply alignment data in clinical decision-making.
3D Slicer
3D Slicer is a free, open-source medical image computing platform that supports advanced visualization, segmentation, and quantitative analysis of CT, MRI, and radiographic data, including spine-specific applications. For spine imaging, it is frequently used for vertebral body segmentation, landmark-based measurement, 3D reconstruction, and development of custom analytics pipelines. Its modular architecture allows integration of plug-ins for automation, AI/ML workflows, and novel measurement development, making it particularly well suited for exploratory research, measurement standardization efforts, and innovation beyond traditional alignment metrics.
ITK-Snap
ITK-SNAP is a free, open-source software application optimized for semi-automated segmentation of 3D medical imaging data, particularly CT and MRI. In spine-focused research, ITK-SNAP is commonly used for precise delineation of vertebral bodies, intervertebral discs, spinal canal, and paraspinal musculature. Although it offers fewer built-in alignment or deformity measurements compared with spine-specific platforms, its strength lies in reproducible segmentation and landmark annotation, which can serve as the foundation for downstream quantitative analysis.
