    • A medical data processing method of determining a spatial relationship between a marker device (1, 1', 1", 20) and a resection plane (50, 120) associated with an anatomical structure (5, 12) of a patient's body, the marker device (1, 1', 1", 20) being video- detectable by an imaging unit (6), the method being constituted to be executed by a computer and comprising the following steps: a) acquiring imaging unit position data describing a predetermined spatial relationship between the imaging unit (6) and the resection plane; b) acquiring marker device position data describing a spatial relationship between the marker device (1, 1', 1", 20) and the imaging unit (6) based on imaging the marker device (1, 1', 1", 20) with the imaging unit (6) in order to generate an orientation-dependent image appearance of the marker device (1, 1', 1", 20); c) determining, based on the imaging unit position data acquired in step a) and the marker device position data acquired in step b) and based on the orientation- dependent image appearance of the marker device (1, 1', 1", 20), resection plane (50, 120) data describing the spatial relationship between the resection plane (50, 120) and the marker device (1, 1', 1", 20).
    • 一种用于确定与患者身体的解剖结构(5,12)相关联的标记装置(1,1',1“,20)和切除面(50,120)之间的空间关系的医学数据处理方法, 标记装置(1,1',1“,20)由成像单元(6)可视频检测,该方法被构造成由计算机执行,并且包括以下步骤:a)获取描述a的成像单元位置数据 成像单元(6)与切除面之间的预定空间关系; b)基于对所述标记装置(1,1',1“,20)成像来获取描述所述标记装置(1,1',1”,20)和所述成像单元(6)之间的空间关系的标记装置位置数据, 与成像单元(6)相关联,以便产生标记装置(1,1',1“,20)的取向相关图像外观; c)基于在步骤a)中获取的成像单元位置数据和 基于步骤b)中获取的标记装置位置数据,并且基于标记装置(1,1',1“,20)的取向相关图像外观,切除平面(50,120)的数据描述切除的空间关系 平面(50,120)和标记装置(1,1',1“,20)。
