GUI for Physical Parameter Mapping in Medical Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical procedures like heart electrical activity mapping, the need for speed can lead to inefficiencies in data collection, particularly in identifying and measuring physical parameters like local activation times across multiple locations within the heart.
Innovation Solution
A method that involves measuring physical parameters at multiple locations, analyzing these values to identify gaps, and displaying candidate locations for further measurement, using a graphic user interface to visually differentiate measured and unmeasured values, allowing users to select and re-measure until all areas are evaluated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If measurements are performed quickly to complete the procedure in short time, then procedure speed is improved, but measurement completeness deteriorates leading to inefficiencies in data collection
Solution Approach 1:
The system provides visual feedback through a number line display that shows measured values, unmeasured sub-ranges, and candidate locations. This feedback mechanism guides the operator to efficiently identify and measure missing data points, improving data collection completeness without sacrificing procedure speed
Solution Approach 2:
The system performs preliminary analysis of measured values to identify sub-ranges containing unmeasured values before the operator continues measurements. By pre-processing data to highlight gaps and suggesting candidate locations, the system prepares the next measurement targets in advance, preventing data collection inefficiencies
2Measurement precision
If comprehensive measurement of all locations is performed to ensure data completeness, then measurement precision is improved, but procedure time increases
Solution Approach 1:
The system focuses measurements on specific sub-ranges that contain unmeasured values rather than requiring uniform sampling across the entire range. By concentrating efforts on partial areas that need improvement, the system achieves data completeness efficiently without unnecessary measurements
Solution Approach 2:
The measurement process is segmented into discrete steps: measuring values, analyzing to identify sub-ranges with unmeasured values, selecting candidate locations, and re-measuring. This segmentation breaks down the complex task of comprehensive measurement into manageable segments, reducing overall procedure time
3Ease of operation
If the system provides detailed visual guidance for selecting measurement locations, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The number line display uses different visual representations to distinguish measured values from unmeasured sub-ranges. This visual differentiation through color or style changes provides intuitive guidance to operators without requiring complex controls or interfaces

AI summary
A method, including measuring values of a physical parameter at multiple locations in an organ of a subject, and analyzing the measured values to identify a range of the values, including at least one sub-range containing one or more values that were not measured. The method further includes receiving a selection from a user of a value in the sub-range, and, responsive to the selection, displaying a candidate location for further measurement.
