Lung tissue aeration measuring method, involves calculating residual air from highest signal of voxels of measuring object after expiration, where object has change between inhalation and exhalation in comparison with preset region

摘要

The method involves calculating residual air from a highest signal of voxels of a measuring object after expiration, where the measuring object has a change between inhalation and exhalation in comparison to a preset region for calculating a ventilation value. Measurement of a total signal is performed by automatic segmenting of an entire lung. The total signal of an examined patient and maximum intensity pixels are calculated by signal change during the respiration. An automatic size correction of the lung is provided by a computer-based registration algorithm. An independent claim is also included for a device for accurate aeration measurement of a tissue.
