In this paper we introduce a novel non-invasive method that uses structured light to perform pulmonary function testing (PFT). PFT is the general term for a range of clinical tests that can be performed on a patient in order to assess respiratory status. The technique, called Structured Light Plethysmography (SLP), produces an estimate of chest wall volume(More)
PURPOSE Differences in tidal breathing patterns have been reported between patients with chronic obstructive pulmonary disease (COPD) and healthy individuals using traditional measurement techniques. This feasibility study examined whether structured light plethysmography (SLP) - a noncontact, light-based technique - could also detect differences in tidal(More)
Structured light plethysmography (SLP) is a noncontact, noninvasive, respiratory measurement technique, which uses a structured pattern of light and two cameras to track displacement of the thoraco-abdominal wall during tidal breathing. The primary objective of this study was to examine agreement between tidal breathing parameters measured simultaneously(More)
