The problem

Medical imaging analysis for spinal conditions requires a specialist to manually review and annotate MRI and X-ray scans — a process that is time-consuming, expensive, and dependent on specialist availability that is often constrained.

The client needed a proprietary AI segmentation model that could identify spinal structures, flag anomalies, and produce annotated outputs with clinical-grade accuracy — fast enough to be practically useful in a diagnostic workflow.

Generic off-the-shelf vision models lack the domain specificity to perform at clinical accuracy thresholds. The model had to be trained from scratch on labelled medical imaging data to reach the precision required.

What we built

A computer vision solution based on ML segmentation models trained on X-ray and MRI scan datasets. The system identifies spinal structures, segments regions of interest, and outputs annotated results for clinical review.

  • ML model trained on curated X-ray and MRI datasets for spinal anatomy recognition
  • AI segmentation identifying vertebrae, discs, and structural anomalies
  • Annotation output integrated into existing diagnostic review workflow
  • Cost-effective architecture designed for scalable per-scan processing
  • Error rate validated below 10% across the test dataset

The outcome

Error margin below 10% validated across the full test dataset — a threshold that makes the model clinically meaningful rather than just technically interesting.

Diagnostic review time cut by 3× by automating the initial segmentation and annotation step, allowing specialists to focus on interpretation rather than manual marking.
