摘要： A multistage method, according to at least one embodiment of the invention, is disclosed for segmenting an interior region of a hollow structure in a tomographic image. In at least one embodiment of the method, portions of the image are segmented in each of at least two segmentation cycles, respectively, whilst using a substance-specific segmentation criterion. Using this procedure, the interior region of the hollow structure can be completely determined, even in the case where a plurality of substances with different imaging properties, e.g. with different attenuation properties, are present.

摘要： A method and an apparatus are disclosed for registering at least three different image data records for an object. In at least one embodiment, the method involves first of all determining for each image data record the anatomical region which is covered by the image data record. Next, degrees of overlap in these anatomical regions are calculated. These degrees of overlap are taken as a basis for determining the image data record as a master image data record which, in total, has a maximum overlap with the other image data records, ignoring degrees of overlap which are below a prescribable lower threshold. The other image data records are then registered merely with the master image data record. Thus, they are automatically also indirectly registered with one another. At least one embodiment of the present method and the associated apparatus reduce the waiting time for the user who wishes to visualize a plurality of the image data records simultaneously next to one another or superimposed on one another.
摘要翻译：公开了用于为物体注册至少三个不同图像数据记录的方法和装置。在至少一个实施例中，该方法首先针对每个图像数据记录确定由图像数据记录覆盖的解剖区域。接下来，计算这些解剖区域中的重叠度。将这些重叠程度作为将图像数据记录确定为与其他图像数据记录总共具有最大重叠的主图像数据记录的基础，忽略低于可规定的下阈值的重叠度。然后其他图像数据记录仅与主图像数据记录一起登记。因此，它们也被间接地彼此注册。本方法和相关设备的至少一个实施例减少了希望将多个图像数据记录彼此同时显现或叠加在一起的用户的等待时间。
