What effect does higher kilovolt peak (kVp) have on DXR images?

Higher kilovolt peak (kVp) significantly influences the quality and characteristics of DXR images by increasing the penetration power of X-rays. When kVp is elevated, the energy of the X-rays produced becomes higher, which allows these X-rays to penetrate denser tissues and materials more effectively. This increased penetration is crucial for obtaining clearer images of internal structures, as it improves the differentiation between different types of tissue.

In terms of contrast, higher kVp can lead to a reduction in image contrast because it allows more X-rays to pass through both dense and less dense areas. This means that the differences in attenuation between various tissues may not be as pronounced, potentially leading to less visual distinction between those tissues. However, the overall exposure can be improved, reducing the likelihood of underexposure in thicker body parts.

This understanding of kVp is essential for optimizing imaging parameters in DXR, ensuring that images provide sufficient detail for accurate diagnosis without unnecessary radiation exposure. Achieving the right balance in kVp is crucial to maximize image quality while maintaining patient safety.
