Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging systems, particularly Picture Archival Communication Systems (PACS), require manual and time-consuming processes for diagnosing, planning, and post-surgery follow-up of septal defects, which are inefficient and cause additional pain to patients.
Innovation Solution
A system and method utilizing gated MRI data and heart atlas data registration, flow-balance measurement, and computer-assisted detection to identify and measure septal defects, generating diagnostic reports for surgery planning and post-surgery evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual search and measurement methods are used by radiologists and surgeons, then diagnostic accuracy can be maintained, but time consumption increases significantly
Solution Approach 1:
The patent introduces a computer-based image processing system as an intermediary between the imaging equipment and the radiologist/surgeon. This system automatically performs defect detection, localization, and measurement using software algorithms that analyze medical images, thereby maintaining diagnostic accuracy while dramatically reducing the time required for these tasks.
Solution Approach 2:
The patent replaces the manual mechanical process of visual inspection and measurement by radiologists with an automated computer-based image analysis system. The computer algorithm automatically detects defects, measures their dimensions, and provides quantitative analysis, substituting human manual operations with automated computational processes.
2Loss of information
If multiple imaging modalities and manual processes are used for diagnosis and follow-up, then comprehensive diagnostic information can be obtained, but workflow complexity increases
Solution Approach 1:
The patent creates a multi-functional integrated system that combines defect detection, localization, measurement, and follow-up evaluation capabilities in a single computer-based platform. The system can handle multiple imaging modalities and perform various diagnostic tasks through unified software modules, reducing workflow complexity while maintaining comprehensive diagnostic information.
Solution Approach 2:
The patent merges previously separate manual processes for diagnosis, surgery planning, and post-surgery follow-up into a single integrated computer-based workflow. The system combines image processing, defect detection, measurement, and comparison functionalities into one unified platform, simplifying the overall workflow while preserving all necessary diagnostic information.
3Measurement precision
If traditional manual methods are used for post-surgery evaluation, then surgical success can be assessed, but patient discomfort increases due to repeated procedures
Solution Approach 1:
The patent establishes a baseline defect map before surgery that can be used for comparison in post-surgery evaluations. This preliminary documentation allows radiologists to compare pre- and post-surgery images using the same automated detection and measurement system, accurately assessing surgical success without requiring additional invasive procedures or causing extra patient discomfort.
Data Source
AI summary
Certain embodiments of the present invention provide systems and methods for detecting septal defects. In an embodiment, the method may include acquiring gated MRI data and heart atlas data. A registration of the gated MRI data and the heart atlas data may be performed as well as a flow-balance measurement. An atrial septal detection and ventricular septal detection may be performed, as well as a septal measurement. A diagnostic report may be generated detailing the location and properties of the septal defects. A physician may utilize the diagnostic report for surgery planning. After surgery, the diagnostic report may be compared with a post-surgery diagnostic report to determine the success of the surgery.
