Solution Overview
Problem
Current sonographic devices lack an effective user interface for accurately selecting and visualizing the size of catheters or other devices for placement in vascular structures or organs, which can complicate precise procedures.
Innovation Solution
A graphical user interface for sonographic systems that displays a sonographic image with reference objects representing catheter sizes, allowing users to select and overlay these objects on the image, with the ability to change size and position them proportionally to the insertion depth, using a grid-like pattern for measurement units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sonographic devices are used without reference objects, then the device complexity is low, but the measurement precision for catheter size selection is insufficient
Solution Approach 1:
The patent creates graphical copies of catheters (reference objects) that are displayed on the sonographic image. These reference objects are scaled versions of actual catheters, allowing direct visual comparison between the reference object and the anatomical structure. This copying approach enables precise size determination without adding complex physical measurement devices.
Solution Approach 2:
The patent overlays a two-dimensional graphical user interface with reference objects onto the existing sonographic image display. This adds a new dimensional layer of information (the reference objects) to the traditional ultrasound view, enabling size comparison without altering the fundamental sonographic imaging capability or requiring additional physical dimensions.
2Adaptability or versatility
If the sonographic image size is changed to accommodate different insertion depths, then the adaptability to different procedural conditions is improved, but the measurement precision may be compromised
Solution Approach 1:
The reference objects are dynamically scaled based on the insertion depth setting. When the insertion depth changes, the system automatically adjusts the size of the reference objects to maintain accurate proportional representation. This dynamic adjustment ensures that the reference objects remain valid measurement references regardless of the imaging depth or magnification level.
Solution Approach 2:
The system changes the display parameters of the reference objects (their size and position) in response to changes in insertion depth parameters. By dynamically modifying these visual parameters while maintaining the underlying scaling relationships, the system preserves measurement accuracy across different imaging conditions without requiring separate reference sets for each depth.
3Adaptability or versatility
If multiple catheter sizes need to be compared, then the versatility of the interface is improved, but the ease of operation decreases due to increased complexity in selecting and comparing multiple reference objects
Solution Approach 1:
The patent displays multiple reference objects (different catheter sizes) as separate, distinct graphical elements on the sonographic image. Each reference object represents a specific catheter size and can be independently selected. This segmentation allows users to compare multiple sizes simultaneously without confusion, as each option is visually distinct and clearly labeled.
Solution Approach 2:
The graphical user interface acts as an intermediary between the user's selection needs and the actual catheter choice. The interface provides tools for selecting, highlighting, and comparing reference objects, mediating the complex task of choosing the right catheter size by presenting it in an organized, interactive manner that simplifies the decision-making process.

AI summary
A user interface for a sonographic device is disclosed that displays a sonographic image and at least one reference object corresponding to a catheter size. The reference object may be scaled in proportion to the sonographic image. In addition, the user interface may further display a plurality of vertical lines and a plurality of horizontal lines arranged in a grid-like pattern and placed over the sonographic image. The size of both the sonographic image and the at least one reference object may change in proportion to a chosen insertion depth. A display device, a sonographic device and corresponding methods are also disclosed.
