  • DiscussionOur study determined the average excursion of the diaphragms during tidal breathing in a standing position in a health screening center cohort using dynamic chest radiography (“dynamic X-ray phrenicography”). These findings are important because they provide reference values of diaphragmatic motion during tidal breathing useful for the…[Read more]

  • Imaging Protocol of Dynamic Chest Radiology (“Dynamic X-Ray Phrenicography”)Posteroanterior dynamic chest radiography (“dynamic X-ray phrenicography”) was performed using a prototype system (Konica Minolta, Inc., Tokyo, Japan) composed of an FPD (PaxScan 4030CB, Varian Medical Systems, Inc., Salt Lake City, UT, USA) and a pulsed X-ray generator…[Read more]

  • The denominator of this equation is the sum of the reciprocals of the elastic moduli of each individual layer multiplied by a geometric factor which depends on the contact radius and individual coating and substrate thicknesses. In fact the thickness contributions in each term represent the distance of the top and bottom of the individual layer…[Read more]

  • Image AnalysisThe diaphragmatic motions on sequential chest radiographs (dynamic image data) during tidal breathing were analyzed using prototype software (Konica Minolta, Inc.) installed in an independent workstation (Operating system: Windows 7 Pro SP1; Microsoft, Redmond WA; CPU: Intel Core i5-5200U, 2.20 GHz; memory 16 GB). The edges of the…[Read more]

    Recently, dynamic chest radiography using a flat panel detector (FPD) system with a large field of view was introduced for clinical use. This technique can provide sequential chest radiographs with high temporal resolution during respiration (17), and the acetanilide dose is much lower than that of CT. Also, whereas CT and MRI are performed in…[Read more]

    Multiple linear regression analysis using all variables as factors (Model 1) demonstrated that weight, BMI, and tidal volume were independently associated with the bilateral excursion of the diaphragms (all P < 0.05) after adjusting for other clinical variables, including age, gender, smoking history, height, VC, %VC, FEV1, FEV1%, and %FEV1. There…[Read more]

  • 1.Targeting: Distributions of item thresholds and person estimates were relatively well matched, but there was significant item bunching and some gaps at the highest end of the continuum. This indicates a significant ceiling effect. The peak of the information plot was just above 0 logits of the continuum, indicating the best point of measurement…[Read more]
