Understanding the Dosimeter Indicator

The dose indicator is displayed at the bottom of relevant radiographic images.

Indicator	Description
Red and low	A dose indicator that displays red to the left of the band denotes an underexposed image. To improve such an image, increase the x-ray dose by increasing the exposure time or mA value.
Red and high	A dose indicator that displays red to the right of the band denotes an overexposed image. To correct this, decrease the X-ray dose by decreasing the exposure time or mA value.
Green and mid-range	A dose indicator that displays green denotes a correctly exposed image.
