摘　　要：X射线成像技术在医疗领域中具有举足轻重的地位,它利用韧致辐射的原理产生X射线,并通过不同组织对特定能量X射线吸收系数不同而产生射线密度和能谱分布的图像.主要设备有X射线机、计算机断层扫描(computed tomography,CT)以及数字减影血管造影(digital subtraction angiography,DSA)三种.随着计算机技术、人工智能技术以及材料学的飞速发展,影像技术正在经历广泛而深远的改变.一大批全新的成像技术已经逐渐应用于医学领域,并使现有的X射线成像技术飞速发展.本文综合探讨了X射线三大成像设备的发展历史,以及未来技术的主要突破点,同时还对我国X射线技术可能的发展趋势做出预测并提出建议.X-ray imaging technology shows a great importance in medication,it uses bremsstradiation to produce images of ray density and energy spectrum distribution through different tissues with different X-ray absorption coefficients of specific energy.There are three devices now widely used today,X-ray apparatus,computed tomography(CT)and digital subtraction angiography(DSA).With the development of computer technology,artificial intelligence and material science,imaging technology is undergoing extensive and profound changes.A bunch of brand new imaging technologies has been used in medication and make X-ray technology develop rapidly.This article discussed the history of three X-ray devices and breakthrough points in the future.We also make some prediction and suggestions for the possible development trend of X-ray technology in China.
