Method and apparatus for the progressive loading of medical multidimensional images into a medical application
A method includes a) loading a first number n of image sets with an image size k y , the k y images of which are distributed in a regular manner over a volume, which is to be loaded in its entirety as a result; b) loading a number n x of image sets starting with a factor x=1, with the images loaded in total being distributed in a regular manner over the volume; c) determining a camera distance and voxel size based on the number of images loaded, a camera distance and voxel size being suitable as parameters for a volume rendering; and d) repeating the two preceding steps b) and c) while increasing the number of image sets with a factor x=x+1, until all the images of the volume have been loaded in their entirety and/or until the step sequence ends.
1. A method for the progressive loading of medical, multidimensional images into a medical application, the method comprising:
a) loading a first image set with n=k y images into a memory of a computer, wherein n≧2 and the k y images of which are distributed in a regular manner over a volume, which is to be loaded in its entirety;
b) starting with x=1, loading a further image set with n x =(k y ) x images into a memory of a computer, with the images in the loaded image sets being distributed in a regular manner over the volume;
c) determining a camera distance and voxel size based on the number of loaded images, the camera distance and voxel size being parameters for a volume rendering; and
d) repeating steps b) and c) while increasing the variable x with a factor x=x+1, at least one of until all the images of the volume have been loaded into the memory and until the loading is terminated.
2. The method of claim 1 , further comprising:
repeating b) and c) while increasing the image set size with a factor y=y+1, at least one of until all the images of the volume have been loaded in their entirety and until the loading is terminated.
3. The method of claim 2 , wherein k=2.
4. The method of claim 1 , wherein y=0.
5. The method of claim 1 , wherein y=1.
6. The method of claim 1 , wherein k=2.
7. The method of claim 1 , wherein the image sets are distinct.
8. The method of claim 1 , wherein an image is only loaded once.
9. The method of claim 1 , wherein k y is determined so that the rendering of the volume is performable within a time interval of 1 second.
10. An apparatus for the progressive loading of medical, multidimensional images into a medical application, comprising:
a processor configured to
a) load a first image set with n=k y images, wherein n≧2 and the k y images of which are distributed in a regular manner over a volume, which is to be loaded in its entirety as a result;
b) starting with x=1, loading a further image set with n x =(k y ) x images, the images of the loaded first and second image sets being distributed in a regular manner over the volume;
c) determine a camera distance and voxel size based on the number of loaded images, the camera distance and voxel size being parameters for a volume rendering; and
d) repeat application of the loading and the determining while increasing the variable x with a factor x=x+1, at least one of until all the images of the volume have been loaded and until termination of the loading.
