早期，介入放射学允许进行的影像引导下以前不切开不可能进行的手术操作。这些影像引导下的手术已被证明术后并发症少，恢复快，成本降低【13】。一直关注癌症诊断和治疗的介入放射学原则下，肿瘤介入放射学作为新兴的分支学科已在逐步建立。在影像技术的新技术...

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...

治疗的控制是肿瘤介入术中成像的重要角色。要控制一个治疗，成像系统必须能够监测术中的过程，然而，如刚才所描述的。简单地监测过程并不一定意味着治疗可以控制。在热消融的情况下，控制的消融可以来自给电极重新定位的能力或改进它的效果。术中控制的一个...

Control of the treatment is an important intraprocedural role of imaging. To control a treatment, the imaging system must be able to monitor the process, as just described. However, simply monitoring the process does not necessarily mean th...

大多数肿瘤介入治疗的一个重要挑战是意识到，在某种特定的操作过程中治疗已经足够。在理想的情况下，将设定治疗完成的明确终点。影像学是一种潜在的无创解决方案。 所谓监视（monitoring）是观察到的操作中影像结果的可视性变化。监视的目标不仅要确定治疗是...

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...
