ROBITOM II: robot for biopsy and therapy of the mamma

MR-mammography (MRM) reaches a high sensitivity in detecting breast carcinomas of 3 mm in size at least. In cooperation with the Institute of Diagnostic and Interventional Radiology of the Friedrich-Schiller University of Jena, a manipulator has been developed by the IMB, which combines the advantages of MRM imaging with a minimally invasive biopsy and a possible subsequent therapy. The experiences and results of tests with prototype ROBITOM I were brought into the following prototype ROBITOM II. For use of the therapy applicator (cryo), the guiding channel had to be scaled up and also an active breast coil was built. The well-known tissue drift while biopsy with needles is solved within the new prototype. ROBITOM II is designed according the medical electrical devices for clinical use under the terms of DIN EN 60601. The development work of the basic version ROBITOM II is completed, the approval according to the clinical trials may be expected during the next weeks.
