Hybrid System for Performing a Magnetic Resonance Tomography and a Radiofrequency Ablation, and Method for the Operation Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a hybrid medical system that combines magnetic resonance tomography (MRT/MRI) and radiofrequency ablation (RFA) capabilities. The system uses the high-frequency signals generated by the MRI system to directly power ablation electrodes, allowing for both imaging and treatment (e.g., tumor ablation) using the same hardware. The invention also includes methods for operating the system, such as alternating the use of these signals between imaging and ablation.

Use CasesContent extracted from patent full text and abstract with AI.

• Image-guided ablation of tumors or metastases using a single system
• Minimally invasive cancer treatment procedures with real-time MRI monitoring
• Thermal ablation of tissues (for example, cardiac ablation for arrhythmias) under precise imaging control
• Research and development of therapies requiring both MRI imaging and localized tissue destruction
• Hospitals and clinics seeking to streamline interventional radiology workflows without needing separate machines

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces hardware and operational complexity by combining two systems into one
• Eliminates the need for a separate radiofrequency generator for ablation procedures
• Allows seamless switching between imaging and treatment, improving workflow efficiency
• Potentially lowers costs by reducing equipment needs and maintenance
• Improves patient safety and procedural accuracy through real-time MRI monitoring of the ablation
• Reduces the risk of interference between imaging and ablation procedures, as signals are synchronized
• Provides additional visualization options (e.g., current visualization during ablation via MRI) for better control and feedback

Patent Abstract

The invention relates to a hybrid system for performing a magnetic resonance tomography (MRT) and a radiofrequency ablation on a patient, comprising the following characteristics: a) the hybrid system comprises a magnetic resonance tomography system in which MRT high-frequency signals for carrying out the magnetic resonance tomography can be generated and supplied on an output terminal of the magnetic resonance tomography system; b) the hybrid system comprises at least one ablation electrode for performing the radiofrequency ablation; and c) the at least one ablation electrode is coupled to the output terminal of the magnetic resonance tomography system such that the radiofrequency ablation can be carried out by the at least one ablation electrode by means of the MRT high-frequency signals. The invention also relates to a method for operating such a hybrid system.
