Intravenous Coronary Angiography Utilizing K-Emission and Bremsstrahlung X-Rays Produced by Electron Bombardment

冠状动脉造影技术现状 需要注射造影剂 进入冠状动脉;这个过程是 昂贵且有潜在危险 理论分析表明， 两种不同X射线之间的差异 能源，并通过使用适当的 造影剂和信号处理 技术，冠状动脉造影可以是 通过静脉注射获得。 这 建议是测试的可行性， 没有X射线的方法 管，能够处理必要的 高电子流。 拟议 方法是生成幻影的图像 使用低电极电流（形成 Brookhaven Dynamitron电子加速器 并使用平均值来补偿 电流 如果初步结果是 前景看好，后续工作顺利， 更安全、更低成本的血管造影 技术将产生。

The current technique of coronary angiography requires the injection of a contrast agent into the coronary artery; this procedure is expensive and potentially hazardous theoretical analysis shows that by taking the difference between X-rays at two different energies, and by using an appropriate contrast agent and signal processing techniques, coronary angiograms can be obtained using intravenous injection. This proposal is to test the feasibility of the approach without the development of an X-ray tube that is able to handle the necessary high electron currents. The proposed approach is to generate images of phantoms using low electrode currents (form the Brookhaven Dynamitron electron accelerator) and using averaging to compensate for the low current. If the preliminary results are promising, and follow-up work is successful, a safer and lower cost angiographic technology will result.
