Conditions
Summary
The product under investigation is named Gense EIT-kidney device. This kidney device is a portable and non-invasive imaging modality capable of capturing the cross-sectional bioelectrical impedance distribution of the kidney at multiple current injection frequencies using electrical impedance tomography (EIT). Currently, the kidney device employs a band consisting of 16 equally distributed electrodes around the abdomen. The electrode band is connected to a control unit that switches the electrode stimulation and measurement pairs, then sends the collected measurement to a computational unit for image reconstruction. The images are then post-processed to extract functional kidney images for diagnosis. This kidney device can connect to an external screen, allowing the functional images to be produced and visualized.
