Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying vascular cross-sectional and fluoroscopic images, which include multiple frames, can be cumbersome, making it difficult to find the desired frame, leading to potential errors and inefficiencies in medical procedures.
Innovation Solution
An information processing device that collects and synchronizes vascular tomographic and fluoroscopic images, allowing for the display of corresponding frames simultaneously, with user-designated position alignment to facilitate precise image review.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple frames of vascular cross-sectional and fluoroscopic images are displayed simultaneously, then comprehensive diagnostic information is provided, but it becomes difficult to search for and locate the desired frame
Solution Approach 1:
The patent introduces an intermediary system that automatically associates and synchronizes cross-sectional images with fluoroscopic images based on spatial coordinates and timing information. This intermediary mechanism allows the display system to present comprehensive multi-frame diagnostic information while automatically managing the complexity of frame search through automated association rather than manual searching.
Solution Approach 2:
The patent creates a copied and synchronized representation of the same diagnostic scene from two different imaging modalities (cross-sectional and fluoroscopic). By displaying corresponding frames that represent the same temporal and spatial moment, the system provides comprehensive information while making navigation intuitive, as users can correlate the two image types through their synchronized presentation.
2Loss of information
If multiple frames of vascular cross-sectional and fluoroscopic images are displayed simultaneously, then complete diagnostic data is available, but procedural efficiency decreases due to difficulty in locating desired frames
Solution Approach 1:
The patent performs preliminary actions by automatically associating and synchronizing image frames before display. The system pre-processes the images to establish coordinate-based and temporal associations, so that when multiple frames are displayed simultaneously, the desired information is already organized and locatable, eliminating the need for time-consuming manual search during the diagnostic procedure.
3Reliability
If cross-sectional and fluoroscopic images are displayed together, then erroneous judgement is prevented, but operation complexity increases
Solution Approach 1:
The patent introduces an intermediary association mechanism that automatically links cross-sectional and fluoroscopic images through spatial coordinates and timing data. This intermediary system manages the complexity of coordinating multiple image types, allowing them to be displayed together for improved diagnostic reliability without requiring the operator to manually manage the complexity of synchronizing and correlating the different image modalities.

AI summary
In an imaging system, vascular tomographic images and vascular fluoroscopic images which each include a plurality of frames are collected. A position of an image of the probe included in each of the frames of the fluoroscopic images is acquired. The frame of the fluoroscopic image and the frame of the tomographic image which is taken at substantially the same time as the frame of the fluoroscopic image are displayed at the same time. A position of a blood vessel designated by a user is acquired from the displayed frame of the fluoroscopic image. The frame of the fluoroscopic image which includes the image of the probe at a position closer to the position of the blood vessel designated by the user is displayed at the same time as the frame of the tomographic image which is taken at substantially the same time as the frame of the fluoroscopic image.
