RGB-D imaging used for OSAS diagnostics

Obstructive sleep apnea syndrome (OSAS) is a respiratory disorder increasing its prevalence with significant consequences for pediatric patients. The accurate diagnostics of this syndrome is now very time consuming procedure consisting mainly of video polysomnography in sleep laboratory. Due to absence of sleep laboratories (pediatric sleep laboratory is only at Clinic of Children and Adolescents in Martin), the authors of this pilot study focus on using RGB-D depth imaging for supporting diagnostics of OSAS. Based on questionnaire of pediatric specialists from Rome (Italy) specific dentofacial (craniofacial) features measured on head strongly correlate with OSAS occurrence and patients for more accurate diagnostics can be selected during the primary examination. Authors bring a comparison of some RGB-D sensors and measurements for selected dentofacial features to create supporting, non-invasive, automated and fast method for preliminary confirmation of OSAS.
