This is, together with the advanced Cone Beam reconstruction method, TCOTTM, and MegacoolTM X-ray tube, a prerequisite for obtaining the High Contrast Resolution in X-Y-Z-direction. Result: unsurpassed 3-D imaging changing the view on diagnostic CT imaging.      The CT-scanner becomes an economic and patient-friendly One-Stop“ workplace for Trauma, Stroke and Cardiac examinations. Any angiographic or cerebral study is easily and rapidly performed, without overlap of venous contrast into the arterial phase. Through the acquisition of simultaneously 16 slices the Aquilion 16 reveals new areas of application, especially in the area of CT-Fluoroscopy intervention, High Resolution CT-imaging and in Trauma diagnostics.      Aquilion 16 是东芝公司经过十多年精心研究而开发的新型半秒40排16层螺旋扫描CT。       由于众多资深临床用户的参与，结合东芝丰富的专利技术，Aquilion 16具有非常优异的临床性能： · 独有的0.5毫米 x 16层/360度的采集能力，可得到高分辨率的各向同性图像。 · 常规0.5秒的扫描能力更能满足临床的实际需要。 · 10帧/秒的重建时间，具备实时成像的能力,同样适用于螺旋和非螺旋扫描。       Aquilion 16 开创了影像医学的新纪元。其真正的各向同性能力，使影像医学从传统二维横断面图像的诊断转变到当代的三维容积图像的诊断，这更符合实际的临床需要。当然，所有这一切要归功于东芝专利的高性能 Quantum探测器、彻底解决锥形束失真的 TCOTTM 容积重建算法及超大容量的 MegacoolTM 球管。      人性化的设计、窗口式操作界面及自动化的流程，使影像诊断更简单、更方便。特别适合外伤、神经系统和心脏的检查。GANTRY机架系统       The gantry and the patient couch constitute the scanner. The scanner uses a fan-shaped continuous X-ray beam to scan the region to be examined. Transmitted X-rays are detected and converted into electric signals by New generation Quantum? solid state detectors. The gantry consists of the main body and its support mechanism. The X-ray tube and the detector are mounted facing each other on either side of the gantry aperture. The X-ray tube and detectors rotate continuously about the aperture of the gantry. A slip-ring is employed to transmit power between the gantry and the rotating X-ray high-voltage generator assembly. The gantry may be tilted forward and backward in order to perform tilt scanning. Three-dimensional alignment lights are provided for setting slice positions. Gantry and patient couch operating controls are located on both sides of the front of the gantry housing. The patient guide display indicates the scan status to the operator and the patient. o Aperture：720mm o Tilt Angle：±30°，Remote control or manual control        扫描架由主体和机械支撑结构组成。新一代的QuantumTM 探测器将所接收的扇形X线束转化成电子信号。采用最先进的直接驱动滑环技术，球管连续旋转，可进行连续快速扫描及螺旋扫描。机架及床位控制键设在机架两侧，用于控制床位移动及机架倾角，并显示具体参数，机架可向前后倾斜以完成倾斜扫描，机架上有三维定位灯，可准确定位。 o 机架孔径: 720mm o 最大倾角: ±30度, 可遥控或手控 - 7500KHU MEGACOOL Tube- 7.5兆球管       MegacoolTMX-Ray tube is designed for reliability. The Aquilion 16 uses 0.5 second rotation, standard in all protocols. The MegacoolTMX-Ray tube was developed to withstand continuously high gravitation forces and provide the highest cooling rate yet available during the 0.5 s rotation during all exams. The 7.5 MHu X-Ray tube, with its completely new "Anode-Grounding" technology, includes double-sided bearings and anode interlocked cooling. Dramatically increased cooling surface provides the incomparably high cooling rate of 1.386 MHU/min, differing fundamentally from metal ceramic X-ray tube.        MegacoolTM管球采用了东芝全新的阳极接地、双支撑轴和微孔循环专利技术，专为半秒多层螺旋CT设计的超大容量7.5MHu MegacoolTM管球，具有超强的连续扫描能力和高度的稳定性；令人匪夷所思的超高散热率（1,386kHu/分），特别适合薄层大范围扫描，远远优于传统的金属陶瓷球管。 - High Voltage Generator (60KW)- X线高压发生器       X-ray high-voltage generator is built-in the gantry. The system employs a high-frequency inverter for generating and stabilizing the high voltage supplied to the X-ray tube. Included in the generator electronics are circuits for controlling the speed of the rotating anode in the X-ray tube. Use of a high-frequency inverter system results in high power output coupled with excellent stability. In addition, the system is compact and light weight. o Capable of generating: 60KW o X-ray tube Current : 10-500mA in increments of 10mA o X-ray tube voltage: 80-135kV        高频X-线高压发生器高压发生器安装机架内，其高频逆变系统为管球提供巨大的能量并保证了极好的稳定性。整个系统结构紧凑、轻巧。 o 高压发生器功率：60千瓦 o 输出电流：10-500毫安/10毫安递增 o 管电压：80-135kV - SSMD- 可选择层厚多排探测器      The Aquilion 16 is the only system with 40 parallel detector rows distributed on a total width of 32 mm related to ISO centre.       The special developed state -of -the- art SSMD detectors (Selectable Slice thickness Multi-Row Detector) - enable simultaneous data acquisition of 16 x 0,5 mm for High-Resolution images (e.g. Inner Ear), to 16 x 1 mm mode for Normal (e.g. abdomen) and 16 x 2 mm for the trauma (e.g. wholebody scan). The latter corresponds to a single scan range of 32 mm per rotation.       The smallest possible slice-width of 0.5 mm is not only of crucial importance for the isotropic resolution, but provides also a unique precision in 3D-Reconstructions. The Aquilion 16 is the only CT scanner with the same advantage as a MR-scanner - MPR images have the same quality viewed in any direction. o SSMD ：40 rows X 896 elements o Data acquisition ：16 rows X 896 elements        Aquilion 16 是当今唯一配备了40排x 896单元，Z轴宽度达32mm的超宽探测器的设备。       东芝专利的QuantumTM探测器代表了当今的发展方向。超凡绝伦的SSMD可变层厚多排探测器，既可同时采集16 层0.5毫米层厚的高分辨率图像；也可同时采集16层1毫米层厚的常规图像；更可同时采集16层2毫米层厚的图像，其单次扫描覆盖面可达32毫米， 特别适合全身的大范围扫描或外伤患者的检查。        独有的0.5毫米层厚，不仅可得到对诊断而言至关重要的各向同性高分辨率图像，而且可得到精确的三维重建图像。        只有东芝的Aquilion 16 才可以在图像方面与MR磁共振系统相媲美-即任意方向的MPR图像具有相同的图像质量。 PATIENT COUCH检查床       The patient couch is located in front of the gantry and supports the patient.
