Abstract
A method for computing lung compliance imaging, the method comprising obtaining one or more images of lungs, determining a spatial transformation of each voxel within the lungs between the lungs at an inhale position and the lungs at an exhale position to provide displacement vector estimates for each voxel within the lungs, performing volume change inference operations to determine a volume change between the lungs at the inhale position and the lungs at the exhale position based on an inhale region of interest, an exhale region of interest, and the displacement vector estimates for each voxel within the lungs, computing a lung compliance based on the volume change inference operations.
Claims20
A method for determining lung compliance, the method comprising:
- based on a first image representative of a lung of a patient at a first continuous positive airway pressure (CPAP) and a second image representative of the lung at a second CPAP, determining a spatial transformation of a region of interest (ROI) within the lung;
- based on the determined spatial transformation, determining a volume change for the ROI;
- and
- determining a lung compliance of the ROI based on the first CPAP, the second CPAP, and the determined volume change.
A system comprising:
- memory hardware storing instructions that, when executed on data processing hardware in communication with the memory hardware, cause the data processing hardware to perform operations comprising:
- based on a first image representative of a lung of a patient at a first continuous positive airway pressure (CPAP) and a second image representative of the lung at a second CPAP, determining a spatial transformation of a region of interest (ROI) within the lung;
- based on the determined spatial transformation, determining a volume change for the ROI;
- and
- determining a lung compliance of the ROI based on the first CPAP, the second CPAP, and the determined volume change.
