| 宝石能谱CT 拥有一系列独特的技术，包括宝石探测器、高压发射器、ASIR重组技术、能谱栅技术等，使其具有低剂量高清
成像、能谱成像和动态500 排成像特点，实现了全身0.23mm的极限空间分辨率和类MRI的软组织低密度分辨率，为心脏能量成
像、斑块性质的鉴别及金属伪影的消除提供了全新有效的手段。其特有的高纯度和高通透性的物理学特性，再加上影像链中采样
率的增高，专有的高清算法，使得宝石能谱CT 能够在更低的剂量下，获得更为清晰的图像质量，达到目前业内最高的空间分辨率
和密度分辨率；同时，其独有的能谱栅成像技术，将CT 诊断从形态学带入功能学领域，因此也被称为" 显微CT，病理CT，绿色
CT"，宝石能谱CT 代表了目前CT 发展的趋势，它用准确的绝对CT 值的单能量成像（keV）诊断和基物质成像诊断来取代传统的
相对CT 值的混合能量（kVp）成像诊断，用多参数CT 成像诊断来代替传统的单参数CT 成像诊断，而" 三同"（同时、同源、同向）

| 英文摘要: |
| Discovery CT 750 HD has a series of unique technologies, including gem detectors, high pressure transmitters, ASIR
recombination technology, energy spectrum grid technology and so forth. It has low dose HD imaging energy spectrum imaging and dynamic
500 row imaging characteristics, realize the whole body 0.23 mm limit space resolution and class MRI the soft tissue of the low
density resolution, for the heart energy imaging, plaque nature of the identification and elimination ofmetal artifact provides a neweffective
means. Its unique physical properties of high purity and high permeability, coupled with higher sampling rate in imaging chain proprietary
high clearing method, enables the Discovery CT 750 HD to at lower doses to obtain clearer image quality, achieve high spatial resolution
and density resolution. At the same time, its own spectral grating imaging, CT from morphology into functional areas, greatly improving
the diagnostic accuracy and safety, also known as the "green microscopic CT and pathology CT". Discovery CT 750 HD represents
the current trend of the development of the CT, with its accurate absolute CT value of imaging diagnosis and base material (keV)
single energy relative to replace traditional CT imaging diagnosis value of hybrid energy (kVp) imaging diagnosis, CT diagnosis with
multiple parameters instead of the traditional single parameter CT imaging diagnosis, and "Three-of-a-Kind" (At the same time, homologous,
synthetic) the physical basis to ensure the accuracy of spectral imaging, the spectral CT imaging really goes into the first line of the
clinical diagnosis, to improve the accuracy of the diagnosis of cardiovascular disease and security. For CT in the diagnosis of heart disease
has created new areas and new methods. |
