Two-Dimensional X-Ray Collimation Grid by Ion Beam Etching

9361195 Halverson一种名为Bucky Grid的设备广泛用于增强X射线图像。 滤线栅允许初级X射线辐射不受阻碍地通过，同时阻止散射辐射到达X射线胶片并使图像模糊。 Bucky滤线栅仅限于用于大于1毫米的“斑点”的诊断放射学应用，因此不适用于乳房X线摄影程序。 拟议的调查将确定使用离子束蚀刻和光刻来创建高清晰度的可行性，线宽度小于0.1 mm的高传输网格。本研究的成功结果将导致开发一种医疗设备，该设备将降低产生临床可用图像所需的X射线功率水平，并提供在乳房X线照相术程序中使用的潜力。 ***

9361195 Halverson A device called the Bucky Grid is widely used for enhancing X-ray images. The Grid allows primary X-ray radiation to pass through unimpeded while stopping scattered radiation from reaching the X- ray film and fogging the image. The Bucky Grid is limited in its use to diagnostic radiology applications for "spots" larger than one millimeter, making it unsuitable for mammography procedures. The proposed investigation would determine the feasibility of using ion beam etching and photolithography to create high- definition, high transmission grids with line widths less than 0.1 mm. Successful results from this investigation would lead to the development of a medical device that would reduce the level of X-ray power required to produce clinically usable images and offering the potential of use in mammagrapy procedures. ***
