Abstract：
Since the Coded Aperture technique has been successfully applied on X-ray imaging space telescopes, most attention of its development has turned to its application in medical imaging, for it has a very tempting quality to greatly inhance the detect sensitivity without gravely lower the spacial resolution. Now the artifacts of the coded aperture to image a radioactive object nearby comes up as an problem, and among types of coded apertures the MURA[1] is one of the most discussed. Roberto Arrcosi came up with the solution to remove the artifacts utilising mask and antimask. In this article we present two ways to eliminate the second order aberration based on his works.
