Organ Visualization System Using Confidence Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for visualizing and treating internal organs, such as the prostate, often result in undertreatment or overtreatment due to inadequate visualization of disease progression, leading to potential harm and recurrence of disease.
Innovation Solution
A device and method using a computer system to determine and display confidence and affected zones around the internal organ based on medical examination data, including biopsy and imaging results, providing a personalized three-dimensional image with color gradients to help clinicians accurately assess treatment volumes and preserve critical structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional medical imaging methods (ultrasound, MRI, PET) are used to detect suspect zones, then sensitivity and specificity to pathology are improved, but the ability to accurately determine treatment volumes is worsened because scores from detection algorithms are insufficient to replace biopsy analysis
Solution Approach 1:
The patent introduces an intermediary computational model that bridges the gap between detection imaging and treatment planning. This model integrates multiple data sources (imaging scores, biopsy results, statistical approaches) to generate a probabilistic map of disease distribution, which then serves as a basis for determining treatment volumes without requiring complete biopsy coverage of the entire organ
Solution Approach 2:
The patent transforms qualitative detection scores from imaging examinations into quantitative probability values representing the likelihood of disease presence in different zones. This parameter transformation allows the system to convert subjective radiologist assessments into objective, computable metrics that can be integrated with biopsy data and used to generate precise treatment volume recommendations
2Quantity of substance
If multiple systematic biopsies are performed from the whole prostate, then comprehensive sampling is achieved, but the risk of undertreatment or overtreatment increases due to inadequate visualization of disease progression and treatment volumes
Solution Approach 1:
The patent transitions from two-dimensional imaging representations to three-dimensional probabilistic modeling of disease distribution. By creating a volumetric model that incorporates spatial information and probability gradients, the system provides clinicians with a comprehensive view of disease extent and progression, enabling more accurate determination of treatment volumes and reducing reliance on exhaustive systematic biopsies
3Reliability
If biopsy samples are taken and analyzed, then disease confirmation is achieved, but the ability to estimate treatment volumes is worsened because clinicians must form a mental image of disease distribution without visual aids
Solution Approach 1:
The patent creates a visual copy or representation of the internal three-dimensional disease distribution based on integrated data from biopsies and imaging. This virtual model replicates the complex spatial relationships and probability gradients of disease presence, allowing clinicians to visually assess treatment volumes and disease extent without needing to mentally reconstruct the information from scattered biopsy results
Data Source
AI summary
The invention concerns a device for displaying an internal organ of a patient comprising a computer (2) and a screen (3) connected to the computer in order to display at least one image of the internal organ. According to the invention, the computer is arranged to determine, from at least one medical examination previously carried out on the internal organ, at least one confidence area (10) and/or at least one affected area (11), at least partially encompassing one or more portions (9) of the internal organ where samples have been taken and/or at least partially encompassing one or more areas previously identified as suspect during a medical imaging procedure, and to display, on the screen, the image of the internal organ supplemented with the confidence area and/or the affected area. The invention also concerns a corresponding display method.
