A method includes obtaining a first image of a subject at a first
position, changing a position between the detector and the subject,
obtaining a second image, and pasting the first and images to obtain a
composite image. The first image and the second image may have an amount
of overlap equal to no more than about 30 percent of a field of view of
the detector in a direction of movement between the first image and the
second image, and, according to some embodiments, may have an overlap of
about 4 percent to about 16 percent. This may, in some embodiments,
amount to an amount of overlap of about 1.5 cm to about 6.5 or 12 cm. In
some embodiments, the span of overlap of the images is at least about 30
cm. The geometry of the images may be used to help paste the images
together appropriately.
