摘要： A user interface for a computer-implemented Multi-Planar Reformatting (MPR) system comprises three display areas in which are displayed three orthogonal MPR images of the volume data set; a curve drawing tool to allow a user to define a curve through the volume data set; six selectable icons each representing one of six possible combinations of a plane parallel to one of the orthogonal MPR images and a direction substantially normal to a plane parallel to one of the other two MPR images, using which the user selects an approximate direction for the curve; and a fourth display area displaying a curve-related MPR image related to one or more points along the curve. The icons may be individually selectable to allow user input of adequate orientational information for a curved MPR image, or selectable in pairs for input of directional information for a cross-curve MPR image. Alternatively, three icons may be provided for a cross-curve MPR system. A tool to allow rotation of a curved MPR image about the curve can be provided, as can visual indicators of the depth of the curve within the volume, and of the orientation of the cross-curve image.

摘要： An image processing system is described in which sets of image elements having display values outside of a target range B of display values are each respectively morphologically dilated. The intersection between the morphologically dilated sets of image elements is then identified and those image elements within the intersecting region are removed from the set of image elements having the target range B of display values. This removes image elements incorrectly appearing to have display values corresponding to the target range B of display values due to aliasing effect between regions of image elements having display values either side of the target range B of imaging may be two-dimensional or three-dimensional imaging. The morphologically dilatation is preferably performed with a quasi-circular or a quasi-spherical structuring element having a radius of between two and three voxels.
摘要翻译：描述了一种图像处理系统，其中分别在显示值的目标范围B之外的显示值的图像元素组分别形态地扩大。然后识别形态扩张的图像元素集合之间的交集，并且从具有显示值的目标范围B的图像元素集合中去除交叉区域内的那些图像元素。这样除去由于具有显示值的图像元素的区域之间的混叠效应而与显示值的目标范围B相对应的显示值不正确地出现的图像元素可以是二维或三维成像。形态学上的扩张优选用具有半径在二和三个体素之间的准圆形或准球形结构元件进行。

摘要： A two-dimensional representation along a projection direction is generated from a three-dimensional subject. A connected region is selected by a user within the subject. A projection of this selected region is then generated in the same direction as the two-dimensional representation was projected and the external boundary of the selected connected region identified and marked within the two-dimensional representation. Holes within the projection of the selected connected region may similarly be marked as well as the external boundaries and holes within the projections of any voids within the selected connected region.
