Obstructive sleep apnea (OSA) is a prevalent disorder, affecting approximately one billion individuals globally. In this study, we aim to address the limitations of Polysomnography (PSG), gold standard for OSA diagnosis, by developing SlAction, non-intrusive system that utilizes infrared videos detection in daily settings. Considering privacy-sensitive nature videos, SlAction designed analyze data directly on camera-capturing device, eliminating need transmit video server. With collaboration...
Purpose: This study evaluated the effectiveness of a thin lead sheet based simple shielding method for imaging doses from cone beam computed tomography (CBCT) in image‐guided radiotherapy (IGRT). Methods: The entire body, except region scanned by CBCT, was shielded wrapping 2 mm sheet. Reduction secondary CBCT measured using radio‐photoluminescence glass dosimeter (RPLGD) placed inside an anthropomorphic phantom and changes cancer risk due to effect were estimated BEIR VII model. Results:...
Purpose: We have evaluated the response of Gafchromic EBT3 film in low dose for 6 MV x‐ray beams with two scanning modes, reflection mode and transmission mode. Methods: irradiated Gafcromic using a 60 degree enhanced dynamic wedge (EDW) from Clinac iX Linear accelerator (Varian Medical Systems, Palo Alto, CA). The was scanned different analyzed MATLAB. Results: When 7.2 cGy to film, uncertainty 0.54 0.88 24 similar case irradiation showing 0.51 0.87 result suggests that should be used...
Purpose: To reduce the secondary dose by shielding critical structures and to estimate effect of for during cone beam computed tomography (CBCT) scan in radiotherapy. Methods: The reduction doses CBCT was measured using glass dosimeter as a function material thickness. Lead tin alloy with variable thickness used which has form sheet. scans were performed pelvis mode (125kV, 80mA, 13ms) two dosimeters phantom placed 40 cm from isocenter, 5cm central axis 10cm above couch. 30 assumed image...
Abstract Introduction Adherence to positive airway pressure (PAP) therapy continues be a challenge. The main objective of this study was determine whether mobile text-message reminders increased PAP adherence in veterans with obstructive sleep apnea. Methods This is retrospective 25 patients poor who used the Veterans Affairs ANNIE app receive nightly text message reminders. measured at baseline, 1,and 3 months. A one-way repeated measures ANOVA compare effect time on adherence, specifically...
Abstract Introduction The wearable device may be useful in monitoring sleep. Many studies reported reliable data detecting sleep-wake states and sleep stage proportion healthy adults, However, only a few validation were performed evaluating using the devices patients with obstructive apnea(OSA), which showed insufficient accuracy. We aimed to evaluate reliability of multi-sensory wristband (Fitbit Charge 2) OSA. Methods This was preliminary analysis prospective single-center observational...
