Simplified method for standardization of roentgenographic image quality using penetration quality measurements

A simplified method for standardization of roentgenographic image quality is described. The method employs the concept of penetration quality (PQ) originally established for calibration of x-ray tube potential (kVp). In order to verify that the PQ measurement is useful for standardization of roentgenographic image quality in a clinical situation, a cadaver was selected for patient simulation. It has been shown that PQ may be utilized for roentgenographic technique specification in place of kVp. The validity of this standardization was evaluated subjectively by radiologists.
