與傳統(tǒng)線(xiàn)圈技術(shù)不同，新開(kāi)發(fā)的核磁共振掃描線(xiàn)圈使用效率極高的RF(射頻)能量--克服了對(duì)安全性能的關(guān)注，減少了掃描時(shí)間，對(duì)細(xì)節(jié)所達(dá)到額水平是既往所不能達(dá)到的。

該線(xiàn)圈在美國(guó)、歐洲和亞洲的3T核磁共振臨床檢測(cè)市場(chǎng)已經(jīng)開(kāi)始供應(yīng)。MR設(shè)備公司(MRII; Minneapolis, MN, USA)開(kāi)發(fā)了這種產(chǎn)品，該公司下列產(chǎn)品獲得了CE標(biāo)志認(rèn)證，用于3特斯拉(3T)核磁共振的TEM單通道、發(fā)射/接收、15-元素調(diào)制隊(duì)列頭和超級(jí)線(xiàn)圈。MRII使用Cheetah線(xiàn)圈的商標(biāo)向市場(chǎng)推廣這些線(xiàn)圈。

Cheetah線(xiàn)圈是使用MR設(shè)備公司擁有知識(shí)產(chǎn)權(quán)的ICE(誘導(dǎo)耦連元件)技術(shù)來(lái)設(shè)計(jì)開(kāi)發(fā)的，是以TEM (橫向電磁)為基礎(chǔ)的。在2005年的第二季度，MR設(shè)備公司首次獲得了FDA對(duì)使用GE(Chalfont S. Giles, UK)的Cheetah線(xiàn)圈和Siemens(Erlangen, Germany)3T MRI系統(tǒng)的許可。在2005年度第二季度的晚些時(shí)候，他們通過(guò)了極其重要的Siemens集團(tuán)對(duì)Siemens 3T Trio和Tim systems系統(tǒng)的統(tǒng)一性檢測(cè)。MRII預(yù)期這個(gè)具有里程碑意義的結(jié)果，將會(huì)增強(qiáng)與Siemens的關(guān)系，從而支持他們的3T系統(tǒng)。
 
New MRI Coils
 
In contrast to conventional coil technology, newly developed magnetic resonance imaging coils utilize RF (radiofrequency) power with great efficiency--overcoming associated safety concerns, reducing scan time, and producing levels of detail that were previously not obtainable.

The coils are available for 3T MRI clinical markets in the United States, Europe, and Asia. Developed by MR Instruments, Inc. (MRII; Minneapolis, MN, USA), the company received CE Mark certification for its TEM single channel, transmit/receive, 15-element tuned array head and extremity coils for 3 Tesla (3T) MRI. MRII markets these coils under the brand name Cheetah Coils.

Cheetah Coils are designed with MR Instruments’ proprietary ICE (inductively coupled elements) technology, based on TEM (transverse electromagnetic) patents. In the second quarter of 2005, MR Instruments received its first FDA clearance for the use of Cheetah Coils in GE (Chalfont S. Giles, UK) and Siemens (Erlangen, Germany) 3T MRI systems. Later in the second quarter of 2005, they passed important Siemens corporate conformity testing for the Siemens 3T Trio and Tim systems. MRII anticipates that this significant milestone will expand its relationship with Siemens to support their 3T system requirements.
