传统上,医学图像代表了在特定时刻患者解剖结构的一部分的“快照”。然而,在不同时间拍摄的图像中,图像对象的外观往往是不同的。这种变化可能是由于所采用的图像采集技术的差异,器官位置的变化,或由于病理的发展、进展或消退而发生的。我们开发了一种从3D图像数据中定义血管“树”的方法。然后,这些血管树可以与从同一患者获得的任何类型的二维或三维图像数据进行匹配,并显示血管系统。血管结构的变化不仅可以用来阐明血管随时间的变化,还可以帮助确定其他图像对象的位置和/或变化。由于血管遍布全身,该入路适用于任何解剖区域。
A medical image traditionally represents a "snapshot" of a portion of the patient's anatomy at a particular moment in time. However, the appearance of image objects often varies between images taken at different times. Such changes may occur because of differences in the image acquisition techniques employed, because of shifts in the positions of organs, or because of development, progression, or regression of pathology. We have developed a method of defining vessel "trees" from 3D image data. These vessel trees can then be registered with any type of 2- or 3D image data obtained from the same patient and that show the vasculature. Changes in vascular configuration can then be used not only to clarify vascular changes over time, but also to help determine the location and/or change in other image objects. As vessels are present throughout the body, the approach is applicable to any anatomical region.
