The term hybrid stems from the fact that the two main elements from which these devices are built. Instron biomedical testing open house a simple way to identify the saturation level of a detector is to first capture a quick gain correction at around once all indications of saturation are gone, record the pixel intensity value of the live image. Characterisation of transfer curve, signal to noise ratio and mtf based on a standard reference film or. To achieve this with pixel detectors, where charge collection times are in the ns range, is a real challenge. The detected intensity value needs to be scaled and quantized to fit within this range of value. The large number of pixels, more than 7 million, associated with a large geometrical size allows high resolution images and a large field of view, as required in many ndt fields. The typical spatial resolution degradation caused by the border effect, is mitigated here using larger. As the pixel count increases, the more detailed the image becomes.
