8、mium CT of GE- Discovery750HD, is a new image acquisition and reconstruction platform built on theindustry level LINUX operating system and delivering exclusively datapros ability and high low-contrast detectability mode, which is therevolution in CT image quality and diagnosis mode.宝石 ASiR是源自 GE端宝石

9、能谱CT 的新一代的图像及重建，它采用工业级 LINUX 操作系统，提供了强大的数据处理技术和度分辨率检查，为CT 图像质量和临床模式带来了一次新的。Hi-Fi Actively Denoising System高保动降噪系统In data acquisition, the system selectively modulates the signals withdifferent frequency.

12、像重建技术来减少不必要的图像噪声， 可以提高图像质量的同时降低 50%的剂量，即用更低的输出损耗获得同样的图像质量。One way ofing the overly simplified amptions of the FBPalgorithm is to use a technique called iterative reconstruction (IR). Theunderlying approach for this methodology is the following. At aparticular view angle, wecalculate a synthesized pr

13、ojection byperforming “forward projection” on images of the estimated object.Basically, this is theestimate of the attenuation along this view, butwin important difference. This estimate mimics, as much assible,the pros in real CT scanning in which x-ray photons traverse throughthe object and reach

14、the detector. It mimics the finite (known) focal spotsize by placing the initial location of the x-ray photons over a small area instead of a single po. During the ming of x-ray photoneraction with the object, the size and shof the image voxel (notan amed po) is considered by calculating different p

15、ath lengths forx-ray photons entering the voxel at slightly different orienions andlocations. In a similar fashion, the detector shand size are consieredthrough the ming of the detector response function. Thus thesystem optics are med win IR reconstruction while optics arenot med with FBP.一种克服 FBP 算

16、法过于简化的方法是采用迭代重建（ Iterative Reconstruction，IR）的技术，该技术的基本原理如下：对于某个重建视角，首先在估计的物体图像上通过“前向投影”计算一个综合投影，这是对沿着该视角的衰减的第一次估计，但存在较大误差。这种估计尽可能地模拟真实CT 系统中 X 射线光子穿过物体并到达探测器的过程，通过将 X 射线光子的初始位置设置在一个小区域而非单独的点来模拟有限的焦点大小；在 X 射线光子和物体相互作用的建模过，通过计算光子在轻微不同方向和位置进入体素的路径长度来考虑了重建像素的大小和尺寸（而不是一个假想的点）；采用相同的方式，探测器单元的大小和形状通过探测器响应函

17、数来来建模。通过以上处理，系统光学模型就是通过 IR 重建算法来建立的而非 FBP算法。The synthesized projection is then compared to the actual measurementand the difference betn the two shows the amount of adjustment orupdate needed for the current estimation of the object (image).

20、eotakend. This imageg prothe ms againis muchn of the e the将综合投影与实际测量的投影相比较，两者间的差异代表了当前估计需要校正的量，图像校正的目的是使误差最小化，在校正过，由有限光子统计导致的投影测量波动也被考虑了，也评估个独立测量中的光子统计并将这个信息用于图像校正过程。另外，如果某素值与周围体素的值显著不同，这种差异真实的解剖结构，更可能是由于统计波动或图像噪声引起的，即使是一个小也应该和树相连而非一个孤立些信息被考虑的时候，当前的重建图像就被校正了，这个图像再通过以上的综合和校正过程来获得一个更新的图像。但这种建模过程的一个重建中

21、最耗时的部分是系统光学模型的建立，其价值主要体现在提高重建图像的空间分辨率，而系统统计模型的建立主要体现在改善最终图像的噪声上。The compuionalensity on the ming of the noise portion of theing of the system optics.system is not nearly as big as the mTherefore, by focusingon the ming of the noise properties andthe scanned object, we provide significant benefit for

22、 thoseexaminationst may experience limiions due to noise in thereconstructed images, as a result of lower dose examinations, largepatients, thinner sli , etc. Phrased differently, we gain the dosebenefit by lowering the noise in the reconstructed images so the scanning technique can be reduced with

23、equivalent noise and image quality.建立系统统计模型的计算量没有系统光学模型大，因此，ASIR 算法通过首先建立噪声性质和被扫描物体的模型，能为对噪声抑制要求比较高的检查带来显著好处，比如更低剂量的检查、肥胖、更薄层厚等。也就是说，通过降低重建图像中的噪声能获得剂量上的优势，因此在相同噪声水平和图像质量前提下，扫描剂量可以显著降低。Utilizing ASiR Turbo Platform, images obtained can have equivalent IQ toan acquisition with up to 1.67 times the mA
