Liquid Injector Graphical Interface for Injection Condition Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid injectors for imaging diagnostics fail to maintain optimal imaging conditions due to non-linear changes in image contrast when injecting contrast media at a constant rate, and they complicate operations with text-based numerical data entry, making it difficult for operators to intuitively understand and quickly review injection conditions.
Innovation Solution
A liquid injector with a touch panel interface that displays injection conditions graphically, allowing operators to easily enter and visualize injection rates and times, enabling real-time control of liquid injection based on stored conditions, simplifying input actions and providing quick numerical value checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If numerical data representing injection rate and quantity is entered into the liquid injector, then the injection process can be controlled automatically, but it is difficult for operators to intuitively understand the injection condition from the displayed numerical data
Solution Approach 1:
The patent creates a visual copy of the injection condition as a graphical image rather than displaying only numerical data. The graphical interface reproduces the injection profile visually, allowing operators to intuitively understand the injection condition without interpreting numerical values. This visual copy makes the abstract numerical parameters concrete and easily comprehensible.
Solution Approach 2:
The patent transforms the display parameter from numerical form to graphical form. Instead of showing injection rate and quantity as numbers, the system renders them as visual parameters such as bar heights, curve positions, or graphical symbols that directly represent the magnitude and timing of injection parameters, making them intuitively understandable.
2Productivity
If the liquid injector displays only text data of injection conditions, then the device structure remains simple, but operators cannot quickly review or understand the injection conditions
Solution Approach 1:
The system creates a visual representation (graphical image) that copies the essential information of the injection conditions. This graphical copy allows operators to quickly scan and understand injection parameters at a glance, dramatically increasing the speed of reviewing conditions without requiring detailed numerical analysis.
Solution Approach 2:
The patent adds a visual dimension to the display by transforming one-dimensional numerical data into two-dimensional graphical representations. This dimensional transformation enables faster information processing by the human visual system, allowing operators to comprehend injection conditions instantly rather than reading and interpreting numerical values sequentially.
3Ease of operation
If the liquid injector uses a constant injection rate, then the operation is simple, but the CT value rises nonlinearly and remains at optimum level for a very short period, failing to provide optimum imaging conditions
Solution Approach 1:
The patent implements a dynamic injection rate that changes over time during the injection process. Instead of maintaining a constant rate, the system adjusts the injection rate dynamically to follow a predetermined profile that optimizes the CT value over an extended period. This dynamic control ensures optimum imaging conditions are maintained throughout the examination rather than briefly.
Solution Approach 2:
The injection process is divided into multiple phases with different injection rates. The system applies periodic variations in the injection rate, alternating between higher and lower rates according to a predetermined schedule. This periodic action pattern helps maintain the CT value within the optimum range for an extended duration, providing reliable imaging conditions throughout the examination.

AI summary
The preset invention provides a liquid injector in which, when an injection time period and an injection rate are entered as an injection condition, a condition image having a horizontal width corresponding to the injection time period and including the injection rate as text data is displayed in a condition screen with its vertical axis representing the injection rate and its horizontal axis representing the injection time period at a vertical position in association with the injection rate and a horizontal position in association with the injection time period. The operator easily understands instinctively the injection condition from the horizontal width and the position of the condition image, and since the condition image includes the injection rate as text data, the operator can check quickly the numerical values. Thus, the liquid injector can be provided which allows simple entry and review of the injection condition.
