Abstract
A method is disclosed for processing medical image data which image a structure layer by layer, the image data for at least some layers respectively including a plurality of layer images. In at least one embodiment, the method includes segmentation of the structure in the layer images and determination respectively of a position of a point in a layer image. In at least one embodiment, at least one layer image set is furthermore compiled on the basis of the representative points in the layer images.

A method for processing medical image data which image a structure layer by layer, the image data for at least some layers respectively comprising a plurality of layer images, the method comprising:
- automatically segmenting the structure in the layer images;
- automatically determining a position of a point in one of the layer images, the point being representative of the structure segmented in the layer image, respectively for a plurality of the layer images in which the structure has been segmented;
- and
- automatically compiling at least one layer image set by allocating a layer image to the layer image set, respectively, for a plurality of the layer images, the allocating being carried out on a basis of the determined positions of the representative points in the respective layer images.
A method for processing medical image data which image a structure layer by layer, the image data for at least some layers respectively comprising a plurality of layer images, the method comprising:
- automatically segmenting the structure in the layer images to ascertain a segmentation region;
- automatically determining a layer volume of the structure for each of a plurality of layer images in which the structure has been segmented, on a basis of a respective segmentation region and a layer thickness;
- automatically calculating at least one average layer volume of the structure, for each layer in which the structure has been segmented, by averaging layer volumes of layer images from the layer;
- and
- automatically determining at least one average volume of the structure by summing a layer volume of the structure, respectively, from each layer in which the structure has been segmented.
