Abstract

Devices and methods are provided for acquiring and analyzing an image data file to generate diagnostic information reflecting an individual lung compartment. A lung compartment could be an entire lobe, a segment or a subsegment and beyond, hereinafter subsegments and beyond will be referred to simply as segments. Such analysis is used to assess the level of disease of individual lung compartments, both for quantification of the disease state and for determining the most appropriate treatment plan. This analysis allows the imaging technology to be used as a functional diagnostic tool as well as an anatomical diagnostic tool. To this end, dynamic data or images may also be acquired at specific points throughout the breathing cycle. Since air movement in and out of a lung compartment during the breathing cycle is a direct indicator of lung function in some diseases like emphysema, analysis of images during the breathing cycle will indicate levels of disease. Thus, a physician may be able to determine the nature of the disease, severity of the disease and the most effective course of treatment from a computerized image of the lung.
