Interventional Instrument Event Mapper for Biopsy Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasound imaging-guided biopsy procedures lack the ability to accurately record and reference the moment and location of tissue sampling, making it difficult to determine when and where the biopsy was performed, and providing no clear guidance for subsequent procedures.
Innovation Solution
An interventional instrument event tracking system that transmits signals indicating specific events during a procedure, which are mapped onto images by the imaging apparatus, allowing for the precise recording of instrument location and orientation at the time of events, and storing this information for future reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasound imaging is used to guide biopsy procedures, then the ability to visualize the needle and tissue is improved, but the ability to accurately record and reference the moment and location of tissue sampling is lost
Solution Approach 1:
The patent introduces an intermediary event tracking system that includes a transmitter on the biopsy needle, a receiver in the imaging apparatus, and an event mapper that correlates needle events with imaging data. This intermediary system bridges the gap between the imaging system and the biopsy event recording, enabling precise temporal and spatial documentation of biopsy events without compromising the visualization capability.
2Loss of information
If images are saved for later visualization of needle movement and position, then the ability to review the procedure is improved, but the ability to determine when and where the biopsy was performed is lost
Solution Approach 1:
The event tracking system provides feedback by continuously monitoring needle position and events, and correlating this information with the imaging data in real-time. The event mapper creates a feedback loop that links procedural events with their corresponding spatial and temporal context in the imaging record, enabling accurate post-procedure analysis and determination of biopsy locations and timing.
3Ease of operation
If no reference point is provided for subsequent biopsies, then the procedure simplicity is maintained, but the ability to guide and compare subsequent procedures is lost
Solution Approach 1:
The system performs preliminary action by recording and storing the precise location, orientation, and timing of each biopsy event during the current procedure. This pre-documented information serves as a reference for future procedures, allowing operators to plan and execute subsequent biopsies more effectively by comparing them against the stored reference data, thereby enhancing adaptability while maintaining operational simplicity.

AI summary
A system (102) includes an interventional instrument (104) and an imaging apparatus (106). The interventional instrument includes an interventional instrument event tracking transmitter (116) that transmits an interventional instrument event signal in response to a predetermined interventional instrument event by interventional instrument in connection with an interventional procedure for a region of interest of a subject. The imaging apparatus (106) includes an imager (132) that generates image of the region of interest of the subject. The imaging apparatus (106) further includes a receiver (126) that receives the interventional instrument event signal. The imaging apparatus (106) further includes an instrument event mapper (128) that maps the predetermined interventional instrument event to the image based on the received interventional instrument event signal.
