Real-time 3D imaging is likely to play an important role in the proper placement of an ablation probe to cover the tumor entirely in three dimensions. Physiologic information is particularly helpful in differentiating viable from necrotic...
旋转平板透视最近的进展(或锥束CT,cone-beam CT)结合了类CT多平面成像透视的实时成像的优点【5254】。这些图像的表现在肿瘤检测方面优于标准血管造影【55】。软件可用于三维血管造影数据重建,在各个方向上显示肿瘤滋养血管并因此提供经导管治疗的引导【5...

The integration of position sensors with interventional devices such as needles and ablation applicators allows them to be tracked in real time, with images obtained during a procedure. When used with multimodality image fusion, the coordi...
机器人已被应用于很多医学领域【94】。现代医学,尤其是现代医学影像学已经进入数字和机器人的时代,着眼于机器人在介入肿瘤学的应用是自然的事。目前介入肿瘤的机器人有两个潜在的角色。首先,他们可以充当臂扩展在透视和透视CT引导下的进行介入手术的操作...
While combined PET/CT, or even PET/MR, systems exist, interventions usually occur with use of CT or MR systems independent of PET equipment. To best utilize these PET images for intervention, they must be fused with the interventional CT i...
Contrast agents are increasingly being applied as interactive tools during intervention. With diagnostic applications, a contrast agent is administered typically once at the beginning of imaging; with intervention procedures, repeated smal...
作为介入标靶影像方式之一,CT透视是在介入手术房间内实时显示操作过程。CT透视允许肿瘤介入医师在房间里实时观察操作过程。传统需要操作医生每次操作后(如穿刺针前进后),在CT扫描房间里外移动。CT透视技术的缺点是辐射剂量的增加,缺乏三维重建【30】。...
很多肿瘤介入手术在影像检查时需要病人空间入口。肿瘤介入医生在进入介入器械时,这一空间入口对于实时引导非常重要。病人可进入空间的程度每种检查设备不一样的。例如,超声和X射线透视提供病人大多数的进入空间。在CT引导介入手术过程中,患获得者的空间是...
