臨床醫(yī)生現(xiàn)在可以使用一種新型的CT(計算機X線斷層攝影術(shù))模擬軟件來繪制任何平面的影像。三維成像技術(shù)可以簡單地通過點的集合來完成，這些點可以是任何橫斷面或者冠狀面定義的，所有的影像都可以在同一個窗口界面來觀察。

由位于美國密蘇里州圣路易斯CMS研發(fā)的Focal4.2CT軟件促進了運算法則的融合，提高了臨床醫(yī)生融合疑難影像的能力，從而獲得更加準確的視角。該軟件與醫(yī)療數(shù)位影像傳輸標準（DICOM）相兼容，可以在各種醫(yī)院的各種成像系統(tǒng)中工作。

Focal軟件還可以在CMS寬帶中工作。通過CMS寬帶，臨床醫(yī)生就能夠通過高速因特網(wǎng)連接來進入軟件系統(tǒng)，這樣就可以任何地方研究和修改影像資料。工作站與工作站之間的通信可以讓使用者在任何Focal工作站之間傳輸影像資料，這樣為影像成像和研究提供了更好的靈活性。

Clinicians can now contour an image from any plane with new computed tomography (CT) simulation software. 3D contouring is simple via points defined on any transverse, digital, or coronal view, all of which can be viewed within the same window interface.
Developed by CMS (St. Louis, MO, USA), the Focal 4.2 CT software’s improved fusion algorithms enhance a clinician’s ability to automatically fuse difficult image sets for a more accurate view. The software is DICOM-compatible and works with any other planning system, in multiple hospital environments.
Focal software is also designed to work with CMS Broadband, where clinicians can access the software via a high-speed Internet connection and review and modify plan data from anywhere. Station-to-station communication lets users move plans between any Focal station for increased flexibility when developing and reviewing plans.
