医用X线成像系统的数字化进展

Digitization advances of medical X-ray imaging system

医学影像技术是医学放射诊断学中最活跃的研究领域之一,而X线成像技术是医学成像的主要技术。文中介绍了医用X线成像系统由传统的成像方式向着数字化方向发展的过程中先后出现的CR、DR成像系统及其优缺点,着重论述了CR成像系统的改进和DR成像系统的关键部件——X射线探测器的种类并预测了X线成像系统的发展趋势。

The medical imaging technique is one of the most active fields of inquiry in medical radiation diagnostics and the X-ray imaging technique is the main one of medical imaging.The CR and DR imaging system including their merits and demerits are introduced,which appear successively with the development of medical X-ray imaging system digitization from the traditional imaging method.The improvement of CR imaging system and the kind of X-ray detector that is the key component of DR imaging system are emphatic re...
