3D/4D Imaging ROI Adjustment via E Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D/4D imaging systems require users to frequently switch between preview and 3D/4D imaging modes to adjust the region of interest (ROI), making the process complicated and inconvenient.
Innovation Solution
The introduction of an E image in the 3D/4D imaging mode allows users to adjust the ROI directly within the 3D/4D imaging mode, with the E image having a larger scan line range than the ROI, enabling real-time refresh and simplifying the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users adjust ROI by switching between preview and 3D/4D imaging modes, then the ROI can be adjusted, but the operation becomes complicated and inconvenient
Solution Approach 1:
The patent merges the ROI adjustment function with the 3D/4D imaging mode by introducing an E image that can be displayed during 3D/4D imaging. This allows users to adjust ROI parameters directly within the 3D/4D imaging mode without switching to preview mode, thereby simplifying the operation flow and improving ease of use.
Solution Approach 2:
The E image serves multiple functions: it displays the current ROI for adjustment, allows real-time parameter modification, and maintains compatibility with 3D/4D imaging operations. This multi-functional design eliminates the need for separate preview mode, reducing operational complexity.
2Productivity
If users frequently switch between preview and 3D/4D imaging modes to adjust ROI, then the ROI can be modified, but the imaging process is interrupted and time is lost
Solution Approach 1:
The patent enables continuous 3D/4D imaging operation by allowing ROI adjustment through the E image display without exiting the imaging mode. Users can modify ROI parameters while the imaging process continues, eliminating interruptions and time loss associated with mode switching between preview and 3D/4D imaging.
Solution Approach 2:
The E image is displayed in advance during 3D/4D imaging to show the current ROI before final imaging occurs. This preliminary display allows users to adjust parameters proactively without waiting for or interrupting the imaging process, thereby maintaining continuous productivity.
3Ease of operation
If the E image has a larger scan line range than the ROI, then real-time adjustment is enabled, but the scan time and data processing increase
Solution Approach 1:
The E image uses a slightly larger scan line range than the actual ROI to ensure complete coverage and allow for flexible adjustment. This excessive action approach guarantees that any possible ROI modification within the displayed area can be accommodated without requiring additional scanning, thereby enabling real-time adjustment while minimizing the increase in scan time and processing resources.

AI summary
A three-dimensional/four-dimensional (3D/4D) imaging apparatus and a region of interest (ROI) adjustment method and device are provided. An ROI is adjusted through an E image in a 3D/4D imaging mode, in which the E image is refreshed in real time when the ROI is adjusted and has a scan line range larger than that of the ROI.
