Electrical impedance tomography (EIT) has been studied to monitor lung ventilation because it is the only real-time lung imaging method without large equipment [1–2]. However, previous EIT systems just provided 2D cross-sectional image with limited spatial information of the lung and unneglectable volume detection error depending on the location of 2D EIT belt relative to the patient's lung. In spite...
This paper proposes a novel fixed pattern noise (FPN) reduction technique for a PD-storage dual-capture image sensor based on the 4-tansistor pixel structure. The knee-point calibration method using a nonfully depleted photodiode by controlling the transfer voltage is proposed, without any modification of the pixel structure or addition of circuit components. The prototype sensor is fabricated using...
