This paper presents a method for obtaining the signal to noise ratio in conventional radiological images and the signal to noise normalized to the dose absorbed by the patient. These quantities are then optimized both by analytical mcthods and by computer analysis using realistic X-ray spectra and patient composítíon and thickness.
