摘要： A method of masking part of an image for display comprises assigning (506) pixel values to respective pixels outside a region of interest (2) to obtain a masked region (3), the pixel values being determined according to a mask function, the mask function being dependent on a distance of a position of a respective pixel to the region of interest (2), for obtaining a smooth transition region (5) in the masked region (3) at a boundary (6) of the masked region towards the region of interest (2). The mask function may be a darkening filter. The pixels in the transition region (5) are assigned brighter pixel values at pixel locations closer to the region of interest and darker pixel values at pixel locations further away from the region of interest.

摘要： A method is presented to calculate the relative contribution of different tissues, or tissue mix, to at least one data element in a medical object data set, the medical object data set containing data elements, the data elements assigning data values to respective positions in a multi-dimensional geometrical space containing more than one tissue, by means by which parameters are calculated for the at least one data element, the parameters being dependent on the data value of the at least one data element and data values of surrounding data elements in the neighborhood of the at least one data element, the parameters being further compared to combinations of said parameters for data elements occurring in the region of boundaries between tissues.

摘要： A method of constructing an object data set of data elements representing a physical property is described, in which the construction of the object data set includes assigning attributes to respective data elements. Such attributes are used, for example, in volume rendering. The construction of the object data set is achieved in such a way that the relative contributions of the physical property to the values of the respective data elements are derived on the basis of the relative contributions of the physical property to the data values of the data elements. These contributions are calculated by modeling transition changes in the image using a plot of grey value and gradient magnitude. Sampling of data points along the maximum gradient allows identification of the ranges of the physical property contributing to the selected voxel and calculation of the relative amounts.
摘要翻译：描述构建表示物理属性的数据元素的对象数据集的方法，其中对象数据集的构造包括将属性分配给各个数据元素。例如，在体绘制中使用这样的属性。以如下方式实现对象数据集的构造：使物理属性相对于相应数据元素的值的相对贡献基于物理属性对数据元素的数据值的相对贡献而导出。这些贡献通过使用灰度值和梯度大小的图来对图像中的转变变化进行建模来计算。沿着最大梯度采样数据点允许识别对所选体素有贡献的物理属性的范围和相对量的计算。
