Methods and systems are provided for reconstruction error assessment for an interventional tool utilized in an image guided interventional procedure. In one example, an error model based on a target lesion position within a tissue, one or more interventional tool parameters, and imaging system parameters may be utilized to estimate an expected reconstruction error for the interventional tool. In another example, when the interventional tool is within the tissue, the expected reconstruction error may be utilized along with observed tool shape and size to infer an actual tool position and shape within the tissue.

A station for tomotactic-guided biopsy in prone includes a table with an aperture, and a tomosynthesis imaging system. A biopsy gun can be mounted on a stage arm assembly disposed below the table. The imaging system and stage arm assembly can be independently rotated and linearly repositioned in one or more dimensions, thereby allowing the tomotactic scan axis to be located relative to a breast being imaged.

A computer-implemented method is for providing a difference image data record. In an embodiment, the method includes a determination of a first real image data record of an examination volume in respect of a first X-ray energy, and a determination of a multi-energetic real image data record of the examination volume in respect of a first X-ray energy and a second X-ray energy, the second X-ray energy differing from the first X-ray energy.
