WARNING:
Good viewing conditions are important for the correct
interpretation of both diagnostic and test images. Make sure
that the light box intensity (luminance) is 3000 and 6000 cd/m²
(4500 and 6500 °K) for mammography. Use a magnifying glass
and use shutters to collimate. Make sure the ambient light is
low.
