Fluorography is the use of relatively intense (50-1000mA), pulsed x-ray exposures (pulses are of short duration and applied at 1-12 pulses/second) to form an x-ray image. 

The resultant images have a relatively high signal to noise ratio (SNR), i.e the images are of better quality than those acquired in fluoroscopy but are obtained at higher doses. The matrix is typically 1024 x 1024 pixels with each pixel representing 10 bits of greyscale information.

Fluorography can be used for diagnostic purposes and was previously widely used as chest photofluorography for mass tuberculosis screening.
