LESS EXPOSURE FACTOR FOR PATIENT Decrease current decrease Time Increase KVP (potential) (kilovolt potential)If Kvp increased – speed of e increses and more energy photons are formed, thus penetrate the body creating imagesINTENSIFYING SCREENSDecreases patient exposure , but decreases film contrast∴ contraindicated intraorally (IOPA)- made of rare earth material QNFACTORS DECREASING XRAY EXPOSURE TO TRACHEALead apronThyroid collarPosition — distance rule 6 feet away position ** (5 ft for cephalometry) How to increase the image quality – increase the distance between object & the cone** 90° - 130° angleALARA – As Low As Reasonably Achievable
