Structured Light Plethysmography: A Futuristic, Non-Contact Method for Assessing Chest and Lung Function

Structured Light Plethysmography (SLP) is an innovative, non-invasive imaging modality that captures dynamic thoracoabdominal movements during respiration using projected light patterns and stereo imaging.Initially developed as a tool to evaluate pulmonary mechanics without physical contact or radiation exposure, SLP is gaining attention in both clinical and research domains.This review outlines current and emerging applications of SLP in respiratory medicine, surgery, and paediatrics, and explores its future potential as an adjunct or alternative to traditional pulmonary function tests and imaging modalities.
