When shielding or overlying anatomy is present, the goal is to keep the image receptor exposure diagnostic while minimizing patient dose. This means adjusting exposure factors rather than leaving them fixed. If feasible, use a higher kVp with a lower mAs to maintain sufficient receptor exposure with less patient dose, because higher energy photons penetrate more efficiently and require less current.Just be mindful that increasing kVp can reduce image contrast, so you must verify the resulting image meets diagnostic quality. Shielding should be used to protect sensitive tissues without compromising the area of interest; if shielding would overly attenuate the beam, adjust factors to preserve receptor exposure while still aiming to minimize dose. In short, tailor exposure factors to keep the image adequate while applying shielding and opting for higher kVp with lower mAs when feasible to reduce dose.
