4.2 Concerning each type of image
(1) Raw images
These are the images obtained by LANMIT. They have not been compensated or corrected
in any way.
(2) Original images
These images are produced from the raw images which have been subjected to offset
processing and gain compensation.
The characteristics intrinsic to the LANMIT detector have been corrected in these images.
They must never be taken outside.
(3) Diagnosis images
These images are produced from the original images which have been subjected to
automatic analysis and diagnosis image processing.
