. By utilizing this power-law behavior, radiologists can maintain image quality while potentially reducing the total radiation dose by adjusting the mAsm cap A s downward as kVpk cap V p is increased. 4. Optimization in Modern CT Scanners

In medical imaging, technicians must balance two competing factors: providing high-quality images for diagnosis and minimizing the radiation dose to the patient. The variable kVpk cap V p Optimization in Modern CT Scanners In medical imaging,

increases, eventually reaching a plateau where further increases offer diminishing returns. 3. Clinical Application: The 15% Rule kVpnk cap V p to the n-th power Clinical Application: The 15% Rule kVpnk cap V

based on a patient’s . Using optimization curves derived from kVpnk cap V p to the n-th power . By utilizing this power-law behavior

results in a disproportionately large increase in radiation dose. Conversely, doubling the kVpk cap V p would result in a much higher than double increase in dose. 2. Dose vs. Image Noise Optimizing imaging parameters like kVpk cap V p mAsm cap A s

(milliampere-seconds) is critical, especially in sensitive cases like pediatric radiology.
