The seanning device comprises navigation means for detecting the position of the sensor relative to the original image. A pixel grid for the reconstructed image is determined, and correspondence between the pixel grid and the sensor data is identified using sensor position detection data. The intensity of pixels is determined from sensor data selected as relevant to the pixel under consideration.Other References
