新型軟件可以用于二維、三維和四維心功能分析（CFA）以及具有CT肺臟檢查選項，最近已經(jīng)投入使用。

3.7版本的Vitrea 2是由Vital影像公司(Minneapolis, MN, USA; www.vitalimages.com)研制開發(fā)的，包括InnerviewGI的增強(qiáng)組件，這是該公司的CT結(jié)腸軟件。3.7版適合提高工作流程以及提高工作效率。Vital影像公司的總裁兼首席執(zhí)行官Jay D.Miller說：“我們特別自豪推出這個版本，因為我們研制了兩種選擇：心臟功能分析與CT肺檢查，以及對Innerview GI進(jìn)行了改進(jìn)。這三種應(yīng)用軟件都能夠?qū)ΜF(xiàn)存程序提供效果更好、成本更低、以及對患者更加友好的替代選擇?！?/P>

CFA選擇項能夠在二維和三維空間內(nèi)觀察正在跳動的心臟。而且，CFA能夠評估左心室射血分?jǐn)?shù)，這是反應(yīng)心臟功能的一項重要指標(biāo)。當(dāng)使用Vital影像的CT心臟功能選項的時候，心血管醫(yī)生能夠在CT條件下充分評估心臟功能。這些工具通過將新型多探頭CT掃描儀的能量和速度最大化，提升了心血管醫(yī)生有效監(jiān)測患者病變的能力。

InnerviewGI選項包括對無干預(yù)平滑通過能力的改進(jìn)，從而使其能夠更加容易地通過結(jié)腸進(jìn)行檢查，能夠更容易地在二維和三維空間進(jìn)行移動。美國放射學(xué)影像網(wǎng)絡(luò)學(xué)院(ACRIN)正在使用這個版本的InnerviewGI，進(jìn)行一項重要的臨床實驗來評估CT結(jié)腸成像與傳統(tǒng)結(jié)腸鏡。
 
Software for Cardiac, Lung Functional Analysis
 
New software for two-dimensional (2D), 3D, and 4D visualization analysis of cardiac functional analysis (CFA) with computed tomography (CT) lung options has been recently introduced.

The Vitrea 2, Version 3.7 was developed by Vital Images (Minneapolis, MN, USA; www.vitalimages.com) and includes enhancements to InnerviewGI, the company’s CT colon software. The Version 3.7 is geared to enhance workflow and productivity. “We are especially proud to launch this version as we have developed two options--cardiac function analysis and CT lung--as well as improvements to Innerview GI. These three applications all potentially offer better, lower-cost, and more patient-friendly alternatives to existing procedures,” said Jay D. Miller, president and CEO of Vital Images.

The CFA option visualizes a beating heart in 2D and 3D. Furthermore, CFA assesses the ejection fraction of the left ventricle--a major measurement of heart function. When used with Vital Images’ CT cardiac option, cardiologists can fully assess cardiac function in the CT environment. These tools strengthen cardiologists’ ability to effectively detect patient abnormalities by maximizing the power and speed of new multidetector CT scanners.

The InnerviewGI option includes improvements to its hands-off fly-through capability that make it easier to visually travel through and examine the colon, along with the ability to move between 2D and 3D images with greater ease. The American College of Radiology Imaging Network (ACRIN) is using this version of InnerviewGI in a major trial comparing CT colonography to conventional colonoscopy.
