西门子推出新型Somatom多层螺旋CT

两种新型多层螺旋计算机X线断层扫描系统业已发布。一种是新型亚秒、双层X线计算机断层扫描系统叫做Somatom Sprit。另外一种是Somatom Sensation 40CT，将在2005年夏天推出。

Somatom Spirit用于临床常规应用，每次旋转获得两层影像但是成本与单层扫描器成本一样。该产品可以做为当前使用的过时的单层轴向或者螺旋扫描器的合适的升级换代产品，做为超负荷工作的CT室的补充设备，或者是经济有效的入门产品。同时还可以配置成为小型偏远诊所的远程放射诊断设备。根据检查类型的不同，在8小时的工作日内最多可以检查50例患者。使用70厘米龙门型圆孔以及能够承受200公斤的患者台，使得能够接受的患者类型几乎是无限的。

The new Somatom Sensation 40 CT system enables the acquisition of 40 slices per rotation with excellent image quality and an extremely high isotropic resolution of below 0.4 mm voxel size in clinical routine. Both systems were developed by Siemens Medical Solutions (Erlangen, Germany).

New Multislice CT Systems
 
Two new multiclice computed tomography (CT) systems have been announced. One is a new subsecond, dual-slice computed tomography (CT) system, called the Somatom Spirit. The second is the Somatom Sensation 40 CT, to be available in the summer of 2005.

The Somatom Spirit is for routine clinical applications and acquires two slices per rotation but costs the same as a single-slice scanner. It is a suitable system to replace outdated single-slice axial or spiral scanners, to be used as an additional CT unit in an overworked facility, or for a cost-effective entry into CT. It is also geared for small outlying clinics utilizing teleradiology. Depending on the kind of exam, up to 50 patients can be scanned in an eight-hour workday. With a gantry aperture of 70 cm and a patient table load of 200 kg, the patient spectrum is virtually unlimited.
