    • A method for selecting vertices for performing deformable registration of imaged objects is provided. The selected vertices form corresponding pairs, each pair including a vertex from a first imaged object and a vertex from a second imaged object. The corresponding vertex pairs are sorted in order of distance between the vertices making up the corresponding vertex pair. The corresponding vertex pair with the greatest distance is given top priority. Corresponding vertex pairs that lie within a selected distance from the selected corresponding vertex pair are discarded. In this manner, the number of vertex pairs used for deformable registration of the imaged objects is reduced and therefore allows for processing times that are clinically acceptable.
    • 提供了一种用于选择用于执行成像对象的变形登记的顶点的方法。 所选择的顶点形成对应的对,每对包括来自第一成像对象的顶点和来自第二成像对象的顶点。 对应的顶点对按照构成相应顶点对的顶点之间的距离的顺序进行排序。 具有最大距离的相应顶点对被赋予最高优先级。 位于距所选择的对应顶点对的选定距离内的相应顶点对被丢弃。 以这种方式,用于成像对象的可变形登记的顶点对的数量减少,因此允许临床可接受的处理时间。
