Conditions bronchiolitis obliterans, lung transplant rejection
Treatment high resolution computed tomography scan
Sponsor FLUIDDA nv
Start date February 2015
End date March 2017
Trial size 8 participants
Trial identifier NCT02364674, FLUI-2014-103_USA


The objective of this study is to detect Bronchiolitis Obliterans Syndrome (BOS) in an early stage using the outcome parameters generated by Functional Respiratory Imaging (FRI). Robust and automated segmentation algorithms will be developed for these parameters, focusing on quantitative computed tomography (CT) image analyses to provide the physician a more sensitive diagnostics tool. The evolution of BOS over time will be monitored using non-rigid image registration methods.
