A method for modifying at least one calculation algorithm in a biopsy system and a biopsy system

摘要

The present invention relates e.g. to a method for modifying at least one calculation algorithm in a stereotactic biopsy system by placing a phantom in a specific position on an object table (92) in the biopsy system and irradiating the phantom from at least two angles (94). The phantom contains markers at exact positions, and the calculation algorithm can be modified (98) on the basis of information on the known positions of the markers and image information in the two exposures (96).
