Virtual Scanned Object Model for MRI Protocol Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for selecting a scanning protocol set in medical imaging, such as MRI, are cumbersome and require multiple clicks, making the process inefficient and not visually intuitive.
Innovation Solution
A method and apparatus that utilize a preset virtual scanned object model to visually select a scanning protocol set by correlating scanned areas with corresponding protocol sets, allowing for quick and intuitive selection through a graphic or image model, with options for user configuration and editing of these correlations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional protocol selection method is used (selecting text version of protocol tree and scanned part node), then the scanning protocol set can be selected, but the process requires multiple clicks (3-6 times) and is not visually intuitive
Solution Approach 1:
The patent creates a virtual scanned object model that is a visual copy or representation of the actual scanned object. This virtual model allows users to interact with and select scanning areas visually rather than through text-based protocol trees, reducing the number of clicks required and making the selection process more intuitive.
Solution Approach 2:
The virtual scanned object model serves as an intermediary between the user and the scanning protocol selection system. Instead of directly interacting with text-based protocol parameters, users interact with the visual virtual model, which then translates their selections into the appropriate protocol settings automatically.
2Ease of operation
If a virtual scanned object model is used for protocol selection, then the selection becomes visually intuitive and requires only one click, but the system complexity increases due to model loading and correlation setup
Solution Approach 1:
The patent performs preliminary actions by pre-loading the virtual scanned object model and pre-establishing the correlation between scanned areas and protocol sets before the user needs to make a selection. This preparation work is done in advance, so when the user needs to select a protocol, they simply need to click on the desired area in the already-loaded visual model without dealing with complex setup procedures.
3Measurement precision
If the virtual scanned object model is aligned with patient positioning direction, then visual accuracy is improved, but additional processing is required to determine and align the positioning direction
Solution Approach 1:
The system performs preliminary determination of the patient's positioning direction and pre-aligns the virtual scanned object model accordingly before the user interaction begins. This ensures that when the user views the virtual model, it is already oriented correctly to match the actual patient positioning, providing visual accuracy without requiring the user to manually adjust or understand complex orientation parameters.

AI summary
In a method and medical equipment for selecting a scanning protocol set, a preset virtual scanned object model including multiple scanned areas is loaded into a computer. The virtual scanned object model is a graphic or image model. A scanned area is selected by use of the virtual scanned object model. A default scanning protocol is set corresponding to the selected scanned area according to a preset correlation between the scanned area and the scanning protocol set, so as to complete the selection of the scanning protocol set.
