3D evaluation of diaphragm function using volume change measurements

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to validate a method for measuring inspiratory capacity (IC) through 3D analysis of thoraco-abdominal volume changes between functional residual capacity (FRC) and total lung capacity (TLC). Participants will undergo 3D visualization while maintaining a supine position and a five-second apnea to assess diaphragmatic function non-invasively. The study will also evaluate the inter-observer variability of IC measurements between trained technicians and pulmonologists. The goal is to enhance understanding of diaphragmatic dysfunction and improve diagnostic accuracy.
