摘要: Currently, High Field (1.5 T) Superconducting MR image-guided needle breast procedures allow the physician only to calculate approximately location and extent of a cancerous tumor in compressed patient before inserting needle. It can then become relatively uncertain that tissue specimen removed during biopsy actually belongs lesion interest. A new method for guiding clinical is presented, based on deformable finite element model breast. The geometry constructed from data, its mechanical properties are modeled using non-linear material model. This allows imaging without compression procedure, compressing predict tumor's position procedure.
