The acquisition of medical images and their display, manipulation, and applications have advanced significantly in the recent past. MR imaging using ultrafast echo planar and fast gradient-echo techniques have expanded application in cardiovascular studies, as well as in the brain and spinal cord. Spiral CT has the potential to revolutionize a well-established modality, subject to several important limitations. The postprocessing of medical sectional images from MR imaging, CT, ultrasound, positron emission tomography, and single-photon emission CT has rapidly grown in importance. We have seen the emergence of renewed and expanded applications of these images, suitably processed, in directing planning and performance of therapeutic procedures on patients through stereotactic techniques, intravascular ultrasound, robot surgery, and integrated displays. This more central role of three-dimensional imaging to medical care is new and will continue to grow. Research applications have recently appeared in neuromorphometry, multimodality registration, functional neuroimaging, quantitative coronary angiography, and saturation MR techniques for myocardial tissue tagging.
医学图像的采集及其显示、处理和应用在最近取得了显著进展。使用超快回波平面和快速梯度回波技术的磁共振成像在心血管研究以及脑和脊髓研究中的应用得到了扩展。螺旋CT有可能彻底改变一种成熟的检查方式，但存在一些重要限制。来自磁共振成像、CT、超声、正电子发射断层扫描和单光子发射CT的医学断层图像的后处理重要性迅速增加。我们已经看到，经过适当处理的这些图像在通过立体定向技术、血管内超声、机器人手术和集成显示器指导对患者的治疗程序规划和实施方面，出现了新的和扩展的应用。三维成像在医疗保健中的这种更核心作用是新的，并且将继续发展。研究应用最近出现在神经形态测量学、多模态配准、功能神经成像、定量冠状动脉造影以及用于心肌组织标记的饱和磁共振技术中。
