    Abstract: An image registration system employs an endoscope and an endoscope controller. In operation, the endoscope generates an intra-operative endoscopic image of a vessel tree (e.g., an arterial tree or a venous tree) within an anatomical region, and the endoscope controller image registers the intra-operative endoscopic image of the vessel tree to a pre-operative three-dimensional image of the vessel tree within the anatomical region. The image registration includes an image matching of a graphical representation of each furcation of the vessel tree within the intra-operative endoscopic image of the vessel tree to a graphical representation of each furcation of the vessel tree within the pre-operative three-dimensional image of the vessel tree.

    Abstract: The invention relates to a brachytherapy apparatus (1) for applying a brachytherapy to a living object. The brachytherapy apparatus comprises a planning unit (14) for determining a placing plan defining placing positions and placing times for one or several radiation sources within the living object and close to a target region. The placing plan is determined such that the placing times are within a treatment time window determined by a treatment time window determination unit (13), wherein within the treatment time window a change of a spatial parameter of the living object caused by swelling is minimized. An adverse influence on the brachytherapy due to swelling can thereby be minimized, which improves the quality of the brachytherapy.

    Abstract translation: 本发明涉及一种近距离放射治疗装置（1），用于对生物进行近距离放射治疗。 该近距离放射治疗装置包括一个计划单元（14），用于确定放置计划，该放置计划定义了将一个或多个辐射源放置在活体内并靠近目标区域的位置和放置时间。 确定放置计划，使得放置时间在由治疗时间窗口确定单元（13）确定的治疗时间窗口内，其中在治疗时间窗口内，由膨胀引起的活体的空间参数的变化最小化。 因此，可以将由于肿胀引起的近距离放射疗法的不利影响降至最低，这提高了近距离放射治疗的质量。

    Abstract: The following relates generally to image segmentation. In one aspect, an image is received and preprocessed. The image may then be classified as segmentable if it is ready for segmentation; if not, it may be classified as not segmentable. Multiple, parallel segmentation processes may be performed on the image. The result of each segmentation process may be marked as a potential success (PS) or a potential failure (PF). The results of the individual segmentation processes may be evaluated in stages. An overall failure may be declared if a percentage of the segmentation processes marked as PF reaches a predetermined threshold.
