To obtain a correct 3D reconstruction of an X-ray scan, it is important that the image
covers the complete scanned object. Therefore the size of the detector will limit the amount magnification, because, by zooming, parts of the object will eventually disappear from the field-of-view. Thus the diameter of an object and the size of the X-ray detector will determine maximal magnification. By repositioning the X-ray detector it is possible to cover a larger area containing the complete object.
Also in optical microscopy there is a trade-off of magnification and field-of-view. Again,
images will be acquired in a tiled fashion to cover a large region. For further analysis of these microscopy images it is crucial that the tiled images are merged in a single
continuous image. Otherwise, the analysis has to be performed on each tile image
separately and border effects would impede this analysis. This problem is avoided when using with a mosaic image.
In fibered confocal microscopy an in-vivo scan is performed, using a fiber optic probe which will conduct the scan image to the microscope. By moving the probe a movie is acquired of the scanned surface. For the analysis of these images it is required to convert these movies to a fixed mosaic image. Also, the resulting mosaic will have better image quality then the constituent movie frames.
