Operative Assistance System for a Magnetic Resonance Tomograph

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

This invention is an operative assistance system for magnetic resonance imaging (MRI) that helps medical practitioners precisely identify and display an entry point on the patient's surface for minimally invasive procedures. The system uses magnetically controlled coils and a luminous indicator (such as a laser or LED) that can be dynamically positioned and oriented using the MRI's magnetic field, allowing the marker to project the planned entry coordinates onto the patient's skin without the need for external mechanical drives.

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

• Guiding needle or probe insertion for biopsies during MRI-guided interventions
• Marking optimal entry points for catheters or surgical instruments in minimally invasive MRI procedures
• Assisting radiologists and surgeons in planning and executing targeted therapies within the MRI scanner
• Supporting interventional radiology workflows for procedures that require precise surface localization
• Providing training and demonstration tools for image-guided minimally invasive techniques

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces the risk of incorrect entry point selection by providing a highly accurate marker on the patient's skin
• Eliminates the need for external, non-MR compatible mechanical drives, improving MR compatibility and safety
• Simplifies the workflow by giving clear visual guidance for the medical team during critical interventional procedures
• Increases the efficiency and precision of minimally invasive treatments performed in the MRI environment
• Decreases patient trauma by enabling better planning and targeting, which may lead to fewer punctures and reduced invasiveness
• Adaptable to various forms of luminous marking (laser, LED, focused lamp), offering flexibility for different clinical scenarios

Patent Abstract

The invention relates to an operative assistance system (1) for a magnetic resonance tomograph (I) for displaying an entry point (IX) for an instrument on the surface of a patient (VIII), comprising at least one device (3) having at least one first holder (IV) for accommodating at least one conductor loop (III), and having a second holder (V) for accommodating at least one luminous means (II) for displaying predefinable coordinates of the entry point (IX)).
