q BOLD Imaging
q 脑功能成像分析软件包
The BOLD（Blood Oxygen Level Dependent） technique is the process that records signal intensities in active regions of the brain. The signal increases during activation due to an oversupply of oxygenated blood in the capillaries. BOLD uses the magnetic susceptibility differences between these blood oxygenation states. As your patient performs the defined task, the blood oxygen levels in the brain increase and are seen in images as signal intensity changes. Correlation Coefficients for mapping of motor strip or visual/auditory stimuli. This type of imaging aids trained physicians in surgical planning and monitoring, as well as during the observation of post surgery patients. It consists of a Single Shot-Gradient Echo Echo Planar Imaging (SS-GRE EPI) pulse sequence used in conjunction with clinical paradigms to visualize signal intensity changes during task activation. Images are produced and post processed into color maps. The color maps display the intensity levels where task activation has occurred.

q 2D PROBE CSI (Chemical shift imaging)
q 二维彩色化学位移成像代谢物含量彩色图
Chemical Shift Imaging (CSI) is an effective and efficient method of simultaneously characterizing the spatial distribution and spectral frequency content of signal producing species in a magnetic resonance (MR) examination. The metabolite maps are a combination of spatial and spectral signal intensity information. The maps are derived from the CSI rank images that can be viewed individually in gray scale in the chemical shift viewport.Average maps are created by combining/averaging several contiguous CSI images. The contiguous regions correspond to the locations of the metabolite resonances or peaks. Ratio maps are a simple extension of the average technique in which two different contiguous sets of CSI rank Images are separately combined, and then divided to produce a ratio map. In essence, a map corresponds to the spatial distribution of the signal intensity of a region of spectrum, or of the ratio of signal intensities in two regions of a spectrum. A numeric list of information appropriate to the current metabolite map or ratio map for each ROI is displayed on this viewport. A metabolite map at a 50% transparency level overlaid on the default image of the localizer series that you selected. The protocol menu provides default metabolite map

q SmartPrep
q 智能化造影剂跟踪血管造影技术
SmartPrep is the focus on automated bolus detection and acquisition triggering for contrast-enhanced MR angiography. SmartPrep uses a tracking pulse sequence to continuously monitor the MR signal coming from a user prescribed volume of interest in the patient. As the signal increases, due to an injected contrast material (e.g., gadolinium), the pulse sequence checks to see if the signal amplitude exceeds a contrast dose-dependent threshold. When the measured signal exceeds the system defined and fixed threshold, the preselected protocol is automatically initiated. SmartPrep uses a tracker volume, also called a tracker pulse, to monitor a region of interest for the arrival of a contrast bolus. SmartPrep uses a three-dimensional imaging volume in order to acquire images. With the correct contrast amount entered, the system automatically chooses the correct threshold value. SmartPrep acquisition consists of three phases:
Baseline phase
Monitor phase
Scan phase
There are two different K-space filling modes, the first of which is Centric K-space Filling. The option for filling K-space would be Elliptic-centric.
智能化造影剂跟踪血管造影技术SmartPrep是一种自动的造影剂跟踪和扫描触发的磁共振血管造影技术。SmartPrep 应用了一个跟踪的脉冲序列来持续监测感兴趣区内指定容积的磁共振信号和造影剂到达情况，造影剂如Gd－DTPA强化信号提高时追踪脉冲一直监控信号的幅值是否超过相应的域值。当系统探测到的信号强度达到域值，预先设定的扫描方案就自动开始扫描。注射后，系统自动选择准确的域值。它的采集包含了三个时相：
基线时相
监测时相
扫描时相

q Fluro-Trigger MRA
q 透视跟踪造影剂触发血管成像技术
Fluoro Triggered MRA uses a thick slab, 2D real time acquisition and reconstruction to monitor the region of interest. It is used to detect the arrival of contrast bolus and then switch es over to the Elliptic Centric view ordered 3D acquisition once the vessels have been sufficiently enhanced. The switch over time is less than 1s. Unlike SmartPrep, the FT-MRA relies on the operator to trigger the acquisition once the Bolus is detected.
If you want to capture angiographic images at the precise moment of peak opacification, fluoro-triggered MRA (FT MRA) is a must have. Rather than automating the image-acquisition upon detection of the bolus arrival, FTMRA allows the operator to manually trigger each acquisition almost instantly, once the operator is satisfied with the level of vessel enhancement. The result is an interactive, ASSET compatible and extremely accurate approach to contrast-enhanced MRA.
透视触发MRA成像应用两维实时采集重建的功能监测扫描的感兴趣区，使操作者能实时观察到造影剂的到达时相，切换到椭圆中心法三维采集，使血管获得充分地增强。透视跟踪从两维采集到自动三维采集的切换时间小于1秒。和自动跟踪造影剂触发的采集不同，透视跟踪的采集时相完全取决于操作者，可根据医生的不同要求对不同的靶血管进行灵活地采样。
如果您想准确抓住血管影像的峰值，FT MRA无疑是必然的选择。相比自动智能化造影，FT MRA是操作者能够自主即时选择采集所需要的血管时相的影像。

q SILENT MR PROPELLER Hardware
q SILENT MR PROPELLER硬件系统
PROPELLER gets its name from its unique K-space acquisition, where data is acquired in radial “blades” that rotate in sequence until the acquisition is completed. Since each blade passes through the center of K-space, Propeller has unusually low sensitivity to motion artifacts and unusually high contrast-to-noise properties. This makes it ideal for producing high-resolution robust image quality in otherwise challenging circumstances. The PROPELLER Hardware is the base of related PROPELLER softwares like the T2 FSE PROPELLER, T2 FLAIR PROPELLER and DWI PROPELLER.
PROPELLER是GE专利的技术，它改变了磁共振的历史，实现了重大的临床突破。它通过独特的K空间采集填充方式，解决了磁共振一直面临的伪影难题，如运动伪影，磁敏感伪影等等。PROPELLER采用螺旋桨式的K空间采集，每一次采集都会采集到K空间的中心数据，这样就可以革命性降低运动伪影，得到优秀的高对比度，高分辨率的图像。因此，有了PROPELLER，不但可以解决磁共振一直面临的伪影难题，而且还可以用它来提高图像质量，从而敏感发现病变。目前，只有在GE的SILENT MR MR上，真正解决了磁共振面临的伪影难题，扫描检查一次成功，MR检查流通量增加15%，MR检查适应症增加20%！为患者、医生、医院增加了巨大的社会效益和经济效益。尤其是在小儿的临床应用，固定不可移动的金属假牙的患者成像方面显示去不可替代的优势。对于配合的患者，PROPELLER 成像完全可以克服生理伪影，如脑积液流动伪影，血管波动伪影，从而获得较常规扫描更高的图像质量，如对比度，信躁比等！在PROPELLER硬件的基础上，可以实现多种序列的应用。 |

PROPELLER(周期性旋转的重复平行线形增强重建采集)是一项革命性的数据采集技术，使用快速自旋回波序列。
The name reflects the unique pattern that acquires radial blades of image data rotated in sequence until data acquisition is complete. The redundant data creates images with unusually high contrast-to-noise ratio as well as makes the sequence insensitive to motion artifacts on T2 and T2 FLAIR sequences and insensitive to susceptibility artifacts on DWI sequences.
该技术名称反映出独有的采集模式，即对放射状的数据进行旋转采集直至序列结束。大量的冗余的数据不仅产生了不同一般的高信噪比图像同时使T2和T2FLAIR序列对运动伪影完全不敏感，使DWI序列对磁敏感伪影完全不敏感。
The result is high quality T2 and T2 FLAIR images of the brain even when the patient fails to remain still, and high quality DWI images in the presence of dental work or surgical hardware. As a result, PROPELLER enables reliable, high quality brain imaging. The Propeller 3.0 version enables multiplane imaging.
结果是脑部的高质量T2和T2 FLAIR图像，哪怕患者没法保持静止。同时可以在假牙患者或脑部术后金属植入物的患者获得高质量的DWI图像。因此PROPELLER能够在上述三种患者中获得可靠的高质量的脑部图像。PROPELLER 3.0能做矢冠轴成像。
