Contextually Enhanced 3D Visualization for Multi-burn Tumor Ablation Guidance

چکیده
We introduce visualization methods for augmented and virtual reality displays that guide minimally invasive tumor-targeting interventions, such as radio-frequency ablation (RFA). Our experimental RFA guidance system performs virtual ablations that geometrically match the real ablations in statically registered phantoms. It provides a head-tracked stereoscopic display that shows a real-time, motion-tracked ultrasound scan, the avatar of a motion-tracked RFA probe, and a registered tumor, which is incrementally “carved” away with each successive ablation pass. An analog bar graph displays tentative ablation coverage fractions for tumor and healthy tissue in real time. We introduce our system, describe the visualization techniques, and present initial results.

A Multi Objective Genetic Algorithm (MOGA) for Optimizing Thermal and Electrical Distribution in Tumor Ablation by Irreversible Electroporation
Background: Irreversible electroporation (IRE) is a novel tumor ablation technique. IRE is associated with high electrical fields and is often reported in conjunction with thermal damage caused by Joule heating. For good response to surgery it is crucial to produce minimum thermal damage in both tumoral and healthy tissues named Non-Thermal Irreversible Electroporation(NTIRE). Non-thermal irrev...
متن کاملOptimizing a Head-Tracked Stereo Display System to Guide Hepatic Tumor Ablation
Radio frequency ablation is a minimally invasive intervention that introduces -- under 2D ultrasound guidance and via a needle-like probe -- high-frequency electrical current into non-resectable hepatic tumors. These recur mostly on the periphery, indicating errors in probe placement. Hypothesizing that a contextually correct 3D display will aid targeting and decrease recurrence, we have develo...
متن کاملPET and MRI-guided focused ultrasound surgery for hypoxic-tissue ablation combined with radiotherapy in solid tumors
Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...
