Biopsy Planning System for Prostate Site Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biopsy methods, such as saturation biopsy, often result in discomfort and potential organ damage due to the need for multiple biopsy sites, and face challenges in accurately visualizing and managing large numbers of biopsy locations, especially in small organs like the prostate, which can lead to inaccurate results and increased complexity across multiple patient visits.
Innovation Solution
A system and method for managing, planning, and displaying biopsy core sites across multiple patient visits using a computer system associated with medical imaging devices, allowing for the creation of composite images that incorporate previous biopsy plans and data, enabling the selection and navigation of biopsy sites with improved accuracy and reduced clutter during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If saturation biopsy is performed with numerous biopsy sites (90 or more), then the confidence and accuracy of biopsy results is improved, but the patient experiences considerable discomfort and the organ may be damaged
Solution Approach 1:
The patent divides the saturation biopsy procedure into multiple separate visits, with each visit containing a manageable number of biopsy sites. The system segments the total biopsy plan into phases, allowing the organ to heal between visits while still achieving comprehensive sampling over time.
Solution Approach 2:
The system performs preliminary planning and visualization of all biopsy sites before the procedure begins. By using 3D imaging and simulation, the operator can identify and mark all target locations in advance, allowing for efficient execution during the actual biopsy procedure.
2Object-affected harmful factors
If the number of biopsy sites is decreased, then patient discomfort and organ damage are reduced, but the probability of accurate results decreases
Solution Approach 1:
The system incorporates feedback mechanisms where biopsy results from previous visits inform the planning of subsequent visits. The visualization system updates to show which areas have been sampled and which remain, allowing the operator to adjust the biopsy plan based on actual findings while maintaining comprehensive coverage.
Solution Approach 2:
The biopsy plan is made dynamic and adaptable. The system allows the operator to modify the plan between visits based on pathology results, patient condition, and organ healing progress. The visualization system dynamically updates to reflect changes in the biopsy strategy.
3Reliability
If a large number of biopsy sites are used, then comprehensive sampling is achieved, but the complexity of managing and navigating to each site increases
Solution Approach 1:
The patent introduces a computer-based visualization and navigation system as an intermediary between the biopsy plan and the physical procedure. This system serves as a mediator that manages the complexity by providing visual guidance, tracking needle positions, and organizing biopsy sites in a user-friendly interface.
Solution Approach 2:
The system creates a virtual 3D copy of the organ with all biopsy sites marked on it. This digital replica allows the operator to plan and visualize the entire procedure before execution, reducing the cognitive load during the actual biopsy by referring to the pre-planned virtual model.
4Reliability
If biopsy sites are densely packed in small organs like the prostate, then comprehensive coverage is achieved, but the sites become hard to visualize and manage
Solution Approach 1:
The patent transitions from 2D imaging to 3D visualization to represent biopsy sites in small organs. By adding the third dimension, the system can display densely packed sites in spatial context, showing their depth and relationship to organ structures, making them easier to distinguish and manage despite high density.

AI summary
Systems are provided for managing, planning and displaying the location of biopsy core sites across multiple same-patient visits or other stored biopsy plans to increase the confidence and accuracy of biopsy results. The systems may allow the operator to fuse multiple predefined and/or automatically generated biopsy core site plans in addition to previous biopsy sites with a current prostate image to assist in creating a final new biopsy core site plan. Further, the system may allow the operator to selectively view singular parts of the final plan to simplify the planning process. Further, the systems may assist the operator during the navigation phase of the biopsy by hiding biopsy core sites from the final plan that are not of immediate interest during the biopsy phase and thereby reducing clutter and distraction during biopsy sample acquisition.
