Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiographic imaging devices experience instability in displaying the orientation of stent images, leading to confusion for operators during coronary intervention procedures, as the stent image may invert or change orientation unpredictably, affecting visibility and operational accuracy.
Innovation Solution
A radiographic imaging device equipped with editing means that ensures specific feature points of the stent image remain oriented in the same direction within the superimposed frame, using alignment and trimming processing to maintain consistent orientation and prevent image inversion, along with input modes for operator-defined reference points to stabilize the image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional superimposition processing is used to generate stent images, then the stent image can be obtained, but the orientation of the stent image becomes unstable and may invert, causing confusion for operators
Solution Approach 1:
The system dynamically adjusts the superimposition processing based on the detected orientation of the stent marker. By continuously monitoring the marker's orientation and adapting the image processing accordingly, the system maintains stable and accurate stent image orientation throughout the procedure, preventing inversion and confusion for operators
Solution Approach 2:
The system uses the stent marker as a feedback reference to continuously monitor and adjust the orientation of superimposed images. The marker's position and orientation information feeds back into the image processing algorithm, ensuring that the stent image maintains correct orientation and preventing inversion during dynamic imaging
2Illumination intensity
If the stent image is enlarged for better visibility, then the visibility improves, but the image requires trimming processing which complicates the display system
Solution Approach 1:
The system performs preliminary orientation determination and marker detection before executing the superimposition and trimming processes. By pre-establishing the correct orientation based on the stent marker, the system streamlines the subsequent image processing steps, reducing overall complexity while maintaining high visibility through proper enlargement
3Measurement precision
If multiple frames are superimposed to clarify the stent image, then the image clarity improves, but the processing time and computational load increase
Solution Approach 1:
The system optimizes the superimposition processing by dynamically adjusting parameters such as the number of frames to be superimposed, the weighting factors for each frame, and the orientation correction angles. These parameter adjustments allow the system to achieve clear stent images through superimposition while minimizing processing time and computational resources required

AI summary
The disclosure provides a radiographic imaging device that improves visibility by preventing a phenomenon in which a stent image is inverted in an enlarged displayed video of a stent image that appears in a live image. Specifically, the present disclosure is provided with a trimming unit that performs editing such that, from among two stent markers indicating the position of a stent image that appears in a superimposed frame generated by superimposing source frames that serve as the source of a live image, a specific stent marker is constantly oriented in the same direction on the frame. As a result of using the trimming unit to edit superimposed frames that are continuously generated, a problem seen in the prior art wherein an object to be displayed within video playback is inverted does not occur.
