An estimated 377 million diagnostic and interventional radiological exams are performed annually in the United States and approximately 4 to 5 billion globally. All use x‐ray tubes that emit x‐rays over a broad energy band, a technology that is more than a century old. Only a small fraction of the radiation is useful for imaging while the remaining fraction either increases the radiation dose received by the patient or degrades the image. Monochromatic x‐rays can provide lower dose images in many of these radiological applications while maintaining or improving image quality. We report the development of the first monochromatic x‐ray source suitable for low‐dose, high‐quality imaging in the clinic and demonstrate its first application and performance with mammography phantoms.

创新的单色X射线源可实现高质量和低剂量的医学成像

在美国，每年大约进行3.77亿次诊断性和介入性放射学检查，而在全球范围内，大约进行4到50亿次。所有人都使用在宽能带上发射X射线的X射线管，这项技术已有一个多世纪的历史了。辐射中只有一小部分可用于成像，而其余部分会增加患者接收的辐射剂量或使图像质量下降。单色X射线可以在许多此类放射学应用中提供较低剂量的图像，同时保持或改善图像质量。我们报告了临床上首个适用于低剂量，高质量成像的单色X射线源的开发，并通过乳房X线照相模体展示了它的首次应用和性能。
