    • A method for registering 2-dimensional (2D) images with 3-dimensional (3D) images includes receiving a 2D reference image and a 3D moving image, initializing a registration parameter matrix that rigidly transforms the domain of the moving image, randomly sampling a set of registration parameter matrices in a neighborhood of the initial registration parameters, estimating a cost function for each of the randomly sampled parameter matrices, calculating a distance from each randomly sampled parameter matrix to the initial registration parameter matrix, calculating a mean shift vector from the estimated cost functions and distance, and updating the initial registration parameter matrix from the mean shift vector.

    • A method for reconstruction of a 3D volume from a set of projection images recorded by a tomography apparatus using penetrating radiation in the field of dental medical applications takes into account a given value of at least one parameter. Simulated projection images are generated which correspond to at least a subset of the recorded projection images by simulating a projection of the penetrating radiation through the reconstructed 3D volume taking into account said given value of the at least one parameter. A re-projection error is determined by comparing the simulated projection images (with the corresponding recorded projection images. The re-projection error is then minimized by changing the value of the at least one parameter and by iterating over the above steps.
    • 从在牙科医疗应用领域中使用穿透辐射的断层摄影装置记录的一组投影图像重建3D体积的方法考虑了至少一个参数的给定值。 通过考虑到所述至少一个参数的所述给定值来模拟通过重建的3D体积的穿透辐射的投影,生成对应于所记录的投影图像的至少一个子集的模拟投影图像。 通过比较模拟的投影图像(与相应的记录的投影图像)来确定重新投影误差,然后通过改变至少一个参数的值并通过迭代上述步骤使重新投影误差最小化。
