Patients with osteoporotic bone are difficult to image as the amount of
kilovoltage peak (kVp) needed to penetrate the condylar area will often cause the jawbones to appear too dark on the image.
Several techniques, such as using optimal
kilovoltage peak (kVp) and the lowest possible milliamperage (mA), can significantly reduce radiation dosage to patients and practitioners.
Kohn et al[10] reported that additive filters of 0.1 mm Cu with 2 mm Al for middle
kilovoltage peak range reduced the exposure to the skin from 30% to 25% and from 45% to 37%, respectively.
