In current clinical practice they are a first\r\nmandatory step before any further medical actions are planned. Performing a biopsy on a deep seated brain tumor\r\nrequires considerable time for establishing and validating the desired biopsy needle pathway to avoid damage.\r\nIn this paper, we present a system for the visualization, analysis, and validation of biopsy needle pathways. Our\r\nsystem uses a multi-level approach for identifying stable needle placements which minimize the risk of hitting\r\nblood vessels. This is one of the major dangers in this type of intervention. Our approach helps in identifying and\r\nvisualizing the point on the pathway that is closest to a surrounding blood vessel, requiring a closer inspection by\r\nthe neurosurgeon. An evaluation by medical experts is performed to demonstrate the utility of our system.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "Teaser",

specific\r\ntissue from where samples are taken. This process is affected by\r\na number of errors that can lead to a different needle pathway\r\nthan originally planned. In the case of brain-tumor biopsies,\r\nthese errors can be caused by the brain shifting when the skull\r\nis drilled, measurement errors due to the physical framework\r\nthat supports the biopsy needle or some other human errors.\r\nTo provide support for preoperative planning, we introduce the\r\nconcept of a biopsy-needle stability-map. This map provides\r\ninformation on how stable a biopsy-needle pathway is. We also\r\nintroduce an algorithm for finding the reachable points on the\r\ntumor border from one specific entry point. A technique for\r\nautomatically selecting the needle pathway that offers the\r\nbiggest minimal distance to any blood vessel is also presented.\r\nA 3D representation of the regions of interest (tumor, blood\r\nvessels) together with the needle pathway and the reachable\r\npoints of the tumor has also been implemented. The resulting\r\nstability map visually represents, using color-coding, how close\r\nto any blood vessel the pathways surrounding the main one are.", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 903, 850, 166 ], "booktitle": "Proceedings of 15th International Conference on System Theory, Control and computing (ICSTCC 2011)", "date_from": "2011-10-14", "date_to": "2011-10-16", "editor": "Editura Universitaria Craiova (EUC)", "issn": "2068-0465", "lecturer": [ 903 ], "location": "Sinaia, Romania", "pages_from": "259", "pages_to": "263", "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "", "filetitle": "Paper", "main_file": true, "use_in_gallery": false, "access": "public", "name": "Groeller_2011_NSM-Paper.pdf", "type": "application/pdf", "size": 254409, "path": "Publication:Groeller_2011_NSM", "url": "https://www.cg.tuwien.ac.at/research/publications/2011/Groeller_2011_NSM/Groeller_2011_NSM-Paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2011/Groeller_2011_NSM/Groeller_2011_NSM-Paper:thumb{{size}}.png" } ], "projects_workgroups": [ "vis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2011/Groeller_2011_NSM/", "__class": "Publication" } ]
