兩種新型多層螺旋計(jì)算機(jī)X線(xiàn)斷層掃描系統(tǒng)業(yè)已發(fā)布。一種是新型亞秒、雙層X(jué)線(xiàn)計(jì)算機(jī)斷層掃描系統(tǒng)叫做Somatom Sprit。另外一種是Somatom Sensation 40CT，將在2005年夏天推出。

Somatom Spirit用于臨床常規(guī)應(yīng)用，每次旋轉(zhuǎn)獲得兩層影像但是成本與單層掃描器成本一樣。該產(chǎn)品可以做為當(dāng)前使用的過(guò)時(shí)的單層軸向或者螺旋掃描器的合適的升級(jí)換代產(chǎn)品，做為超負(fù)荷工作的CT室的補(bǔ)充設(shè)備，或者是經(jīng)濟(jì)有效的入門(mén)產(chǎn)品。同時(shí)還可以配置成為小型偏遠(yuǎn)診所的遠(yuǎn)程放射診斷設(shè)備。根據(jù)檢查類(lèi)型的不同，在8小時(shí)的工作日內(nèi)最多可以檢查50例患者。使用70厘米龍門(mén)型圓孔以及能夠承受200公斤的患者臺(tái)，使得能夠接受的患者類(lèi)型幾乎是無(wú)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 It is a suitable system to replace outdated single-slice axial or spiral scanners, to be used as an additional CT unit in an overworked facility, or for a cost-effective entry into CT.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.
