ABSTRACT:

The study explores the potential of LiDAR (Light Detection and Ranging) technology as a non-invasive alternative for measuting spinal alignment, particularly focusing on the correlation between LiDAR generated data and traditional X-ray measurements. The research involved 275 patients who underwent both full spine X-rays and LiDAR scans. The study compared measurements of Cobb angle, lumbar lordosis and thoracic Kyphosis derived from X-rays and the Spine3D LiDAR system by Sensor Medica. The results demonstrated a strong positive correlation between LiDAR and X-ray measurements across all conditions. The findings suggest that while LiDAR cannot replace X-rays for initial diagnostic purposes, it offers a promising tool for ongoing monitoring of spinal deformities, potentially reducing the frequency of exposure to ionising radiation, and improving patient compliance through engagement. This research highlights the potential for integrating LiDAR technology into clinical practice.
