Title
(EN) GENERATING A LUNG CONDITION MAP
(FR) GÉNÉRATION D'UNE CARTOGRAPHIE DE L'ÉTAT PULMONAIRE
Abstract
(EN)
A biomarker of lung condition can conventionally be obtained using a spirometer. A spirometer provides an estimate of the volume of air expelled by the lungs. This is a rather indirect biomarker of the staging of a lung condition, because a reduction in lung volume may only manifest itself at a point where symptoms are well advanced. A lung condition such as Chronic Obstructive Pulmonary Disorder (COPD) is typically not visible on conventional X-ray attenuation images, because the relevant tissue (alveoli-bearing microstructured lung tissue) contains a lot of air. The X-ray dark- field can successfully indicate microstructure, such as lung alveoli. Therefore, imaging the lungs using the dark-field can provide information on the status of COPD.
(FR)
Un biomarqueur d'état pulmonaire peut classiquement être obtenu à l'aide d'un spiromètre. Un spiromètre fournit une estimation du volume d'air expulsé par les poumons. Ceci est plutôt un biomarqueur indirect de la stadification d'un état du poumon, car une réduction de volume pulmonaire peut ne se manifester qu'à un point où les symptômes sont bien avancés. Un état du poumon tel qu'une bronchopneumopathie obstructive chronique (BPCO) n'est généralement pas visible sur des images d'atténuation à rayons X classiques, en raison du fait que le tissu pertinent (tissu pulmonaire microstructuré portant les alvéoles) contient beaucoup d'air. Les rayons X en champ sombre peuvent indiquer avec succès des microstructures, telles que les alvéoles du poumon. Par conséquent, l'imagerie des poumons à l'aide du champ sombre peut fournir des informations sur l'état de la BPCO.
