Method for acquiring a 3D image dataset associated with an image object

According to the known method of Zhu et al., two 3D image datasets (fA(x) and fB(x)) are calculated when a 3D X-ray image dataset is acquired during scanning of a partial circle by an X-ray radiation source and an X-ray radiation detector, then redundancies are eliminated by averaging the 3D image d...

Summary:According to the known method of Zhu et al., two 3D image datasets (fA(x) and fB(x)) are calculated when a 3D X-ray image dataset is acquired during scanning of a partial circle by an X-ray radiation source and an X-ray radiation detector, then redundancies are eliminated by averaging the 3D image datasets (fA(x) and fB(x)). A filtering that is antisymmetric in respect of a center of symmetry is performed in respect of the 2D image datasets in calculating the second 3D image dataset (fB(x)). Said filtering especially has a row-by-row Hilbert transform (S16). Suitable weights can be specified based on an axis (C) defined in space (S14).
