Global Inhomogeneity Index Evaluation of a DCT-based EIT Lung Imaging

Purpose: To evaluate a novel structural-functional DCT-based EIT lung imaging method against the classical EIT reconstruction. Method: Taken retrospectively from a former study, EIT data was evaluated using both reconstruction methods. For different phases of ventilation, EIT images are analyzed wit...

Method: Taken retrospectively from a former study, EIT data was evaluated using both reconstruction methods. For different phases of ventilation, EIT images are analyzed with respect to the global inhomogeneity (GI) index for comparison. Results: A significant less variant GI index was observed in the DCTbased method, compared to the index from classical method. Conclusion: The DCT-based method generates more accurate lung contour yet decreasing the essential information in the image which affects the GI index. These preliminary results must be consolidated with more patient data in different breathing states.Chen RongqingMöller KnutDe Gruyterarticleeitlung imagingdctgiMedicineRENCurrent Directions in Biomedical Engineering, Vol 6, Iss 3, Pp 36-39 (2020)
