摘要： A system and method for 3D visualization of a pair of lungs are provided. The method comprises: segmenting image data of the pair of lungs and lung parenchyma; generating a 3D map as a function of the segmented image data; and rendering the 3D map as a color-coded semi-transparent 3D volume, wherein an opaque region highlights an area of interest.

摘要： Disclosed is an algorithm for applying a morphological operation to an image. In one embodiment, the morphological operation is iteratively applied to a focal pixel of the image and to another pixel of the image. The other pixel is located at an offset with respect to the focal pixel. The offset is based on an operation count. In another embodiment, the algorithm includes performing a morphological operation on an image using a convex structuring element. A work structuring element having dimensions corresponding to the outer-most dimensions of the convex structuring element is iteratively applied to the image. The dimensions of the work structuring element are then adjusted to correspond to the remaining outer dimensions of the convex structuring element not yet covered by the previous work structuring element. The applying and adjusting steps are repeated until a predetermined number of morphological operations have been performed.
摘要翻译：公开了一种对图像进行形态学运算的算法。在一个实施例中，形态学操作被迭代地应用于图像的焦点像素和图像的另一个像素。另一个像素位于相对于焦点像素的偏移处。偏移量基于操作数。在另一个实施例中，该算法包括使用凸结构元素对图像执行形态学运算。将具有与凸结构元素的最外层尺寸相对应的尺寸的工作结构元素迭代地应用于图像。然后调整工作结构元素的尺寸以对应于尚未被先前工作结构元素覆盖的凸结构元素的剩余外部尺寸。重复施加和调整步骤，直到执行了预定数量的形态操作。

摘要： Disclosed is a method and system for detecting a structure (e.g., an airway) within an image. The method and system generate a segmented image from the original (reconstructed) image. The method and system then iteratively apply three dimensional morphological operators of varying sizes to the image to obtain a resulting image. The method and system obtain a candidate mask, apply the candidate mask to the resulting image to generate a masked resulting image, and update the segmented image using the masked resulting image to detect the structure. In one embodiment, the segmented image is generated from region growing. Also disclosed is a method to determine different regions of interest within a given segmented image based on computed projections and boundary lines of the segmented image.
摘要翻译：公开了一种用于检测图像内的结构（例如气道）的方法和系统。该方法和系统从原始（重建）图像生成分割图像。然后，该方法和系统迭代地将不同大小的三维形态学运算符应用于图像以获得所得到的图像。方法和系统获得候选掩模，将候选掩模应用于生成的图像以产生掩蔽的结果图像，并且使用被屏蔽的结果图像来更新分割的图像以检测结构。在一个实施例中，分割图像是从区域增长生成的。还公开了一种基于计算的分割图像的投影和边界线来确定给定分割图像内的不同感兴趣区域的方法。
