Solution Overview
Problem
Current methods for diagnosing esophageal disorders, such as diffuse esophageal spasm and ineffective esophageal motility, are limited by insufficient information from manometry alone regarding bolus movement, which hinders definitive diagnosis.
Innovation Solution
A system that co-registers and superimposes high-resolution manometry and impedance data sets in both time and position, allowing for intuitive visualization of the interaction between contractile pressure and bolus movement by making the bolus measurement values partially or wholly transparent in contour plots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If high-resolution manometry data is displayed alone, then contractile pressure information is clearly visible, but bolus movement information is missing
Solution Approach 1:
The patent combines manometry data and impedance data into a single unified display. The computer receives both datasets from separate data sources and outputs a composite image that integrates pressure information and bolus movement information, eliminating the need for separate displays and reducing information loss.
Solution Approach 2:
The patent uses transparency as an intermediary technique to layer the two datasets. By making one dataset partially transparent, the system allows both contractile pressure and bolus movement information to be simultaneously visible without completely obscuring either dataset, resolving the information completeness issue.
2Loss of information
If impedance data is displayed alone, then bolus movement information is clearly visible, but contractile pressure information is missing
Solution Approach 1:
The patent merges impedance data and manometry data into a single composite display. The computer integrates both datasets, ensuring that when impedance data is displayed, contractile pressure information is simultaneously present in the same visualization, preventing information loss.
Solution Approach 2:
The patent applies transparency as an intermediary to allow layering of impedance and manometry data. This enables both bolus movement and contractile pressure information to coexist in the display without one completely blocking the other.
3Measurement precision
If multiple datasets are superimposed to provide comprehensive information, then diagnostic accuracy is improved, but data visualization complexity increases
Solution Approach 1:
The patent uses transparency as a mediating technique to manage the complexity of displaying multiple datasets. By controlling the transparency levels, the system achieves comprehensive information display while maintaining visual clarity, thus improving diagnostic accuracy without overwhelming complexity.
Solution Approach 2:
The patent employs different color schemes for different datasets in the composite display. This visual differentiation helps distinguish between manometry and impedance data while allowing both to be displayed simultaneously, enhancing diagnostic accuracy while managing visualization complexity through intuitive color coding.

AI summary
A diagnostic system for display of physiological data in a format useful for identifying or diagnosing physiological conditions. The system registers visual representations of different types of physiological data to aid in an understanding of bodily processes. In addition to registering the data, the system may display different types of physiological data with different visual characteristics. Further, the transparency of the visual representations of the different datasets may be controlled to enhance the understandability of displayed information. The system, for example, can be used with data representative of pressure and impedance within a patient's gastrointestinal tract to provide greater understanding of physiological processes during a swallow.
