The state of lung movement is an important index for the diagnosis of the chronic obstructive pulmonary disease (COPD). To detect the asynchronous movements of the COPD patients’ lung diaphragms, this paper proposes a novel evaluation method of respiratory dynamics, using the metric of average correlation coefficient (ACC) calculated from the diaphragm phase change in sequential sagittal magnetic resonance (MR) images. In our method, first, the diaphragm profile is extracted from the MR image of the sagittal plane of the thoracic cavity, based on the deep learning. Second, the temporal waveforms corresponding to each spaced position of a diaphragm are generated, and the ACC metric on the diaphragm movement is calculated by the similarities between each two waveforms. In the experiments, the proposed method with the ACC metric was confirmed to realize the effective detection of the asynchronous diaphragm movements, for the respiratory dynamics evaluation. |
