【摘要】目的:探析图像增强技术在数字X射线医学影像中的应用。方法:选取2019年1月至2020年12月期间我院放射科行X射线摄影120张摄影图片为研究对象,选择瑞柯双桥(E volution plus)和飞利浦双板DR(Digital Diagonost c50 65型)进行图像处理。将2019年1月-12月期间患者的X射线摄影图像设置为对照组,共60张,将2020年1月-12月期间患者的X射线摄影图像设置为观察组,共60张。对照组使用原片入组,观察组将图片进行增强处理,观察两组图片的清晰度和对比度。结果:观察组图片的清晰度和对比度较对照组优(P<0.05)。结论:将高频加强滤波和直方图均衡技术进行结合,不仅可以增强图像灰度值范围内的对比度,还能清晰地对其细节进行显示,对于临床判定病灶的大小、形状和周围环境情况有着重要的意义。此外,通过增强图像,可以为临床医学图像处理提供一个新的技术平台其适用范围不仅局限于数字 X 射线影响,而对于超声、MRI 等也有着重要的参考意义。

【Abstract】Objective:To explore the application of image enhancement technology in digital X-ray medical imaging. Methods:120 images were selected from January 2019 to December 2.2020, and E volution plus and Philips DR (Digital Diagonast c 5065) for image processing. Set X-ray images from January-December 2019 to control group of 60, with X-ray images from January-December 2020 Set to the observation group with 60 sheets. The control group used the original film to enter the group, and the observation group enhanced the pictures and observed the clarity and contrast of the two groups. Results:The clarity and contrast of the observation group were better than the control group (P <0.05). Conclusion:Combining high-frequency enhancement filtering and histogram equalization technology can not only enhance the contrast within the image gray scale range, but also clearly display the details, which is of great significance for clinically determining the size, shape and surrounding environment of the lesion. Furthermore, by enhancing images, a new technical platform for clinical medical image processing with its application paradigm The circumference is not limited to the influence of digital X-ray, but also has important reference significance for ultrasound, MRI, etc.

引言
X射线发源于19世纪,是德国物理学家伦琴在研究阴极射线管的过程中偶然发现的,经过了半个世纪,科技水平的不断进步发展了超声波成像、放射性同位素成像、核磁共振成像等,被广泛应用于医疗健康领域中来。X射线因其波长短,能量大,照在物质上时,仅一部分被物质所吸收,大部分经由原子间隙而透过,表现出很强的穿透能力。X射线穿透物质的能力与X射线光子的能量有关,X射线的波长越短,光子的能量越大,穿透力越强。……
