Image Diagnostic Apparatus with Dynamic Resolution Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image diagnostic methods using image scanners face challenges in confining pathological changes within a practical image size at appropriate magnification, either under or over magnifying the area of interest, due to fixed block size limitations.
Innovation Solution
An image diagnostic apparatus and method that acquires data at a high resolution, converts it to a lower resolution, extracts regions of interest, determines the presence of characteristic regions, and creates an output image with the characteristic region occupying a predetermined ratio of the image size, allowing for adjustable magnification to ensure appropriate diagnostic image size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed block size processing is used in image diagnosis, then processing capability and display resolution limitations are respected, but the pathological change area cannot be confined to appropriate magnification and practical image size
Solution Approach 1:
The patent applies dynamics by making the block size adjustable rather than fixed. The system dynamically changes the block size based on the magnification level and the size of the pathological change area, allowing the image processing to adapt to different diagnostic requirements while respecting hardware and display limitations.
Solution Approach 2:
The patent changes the parameter of block size from a fixed value to a variable that can be adjusted according to the magnification and pathological area size. This parameter change enables the system to confine the pathological change area to an appropriate magnification and practical image size, resolving the contradiction between magnification precision and image size.
2Area of stationary object
If lower magnification is used to cover larger area, then entire pathological change area can be captured, but the area cannot be confined within practical image size at appropriate magnification
Solution Approach 1:
The patent applies segmentation by dividing the entire pathological image into multiple blocks, where each block can be processed and displayed at the appropriate magnification. This allows the large pathological change area to be captured while confining each segment to a practical image size with appropriate diagnostic magnification.
Solution Approach 2:
The patent transitions from a single fixed magnification view to a multi-magnification block-based view. By organizing the image into blocks that can be individually magnified, the system captures the entire pathological area while providing appropriate diagnostic magnification for each region, effectively adding a dimensional aspect to magnification control.
3Manufacturing precision
If higher magnification is used to achieve appropriate diagnostic detail, then characteristic regions can be clearly observed, but the entire pathological change area cannot be confined within image size
Solution Approach 1:
The patent segments the high-magnification view into multiple blocks, each displaying characteristic regions with appropriate diagnostic detail. This segmentation allows the entire pathological change area to be distributed across multiple blocks, with each block confined to a practical image size while maintaining high magnification for detailed observation.

AI summary
The image diagnostic apparatus includes: acquisition means 11 for acquiring data on an image having a first resolution, which is generated by imaging a diagnostic object; conversion means 12 for converting the resolution of the image into a second resolution which is lower than the first resolution; extraction means 13 for analyzing the image of which resolution has been converted into the second resolution and extracting an ROI of the diagnostic object; determination means 14 for determining whether or not a characteristic region which indicates a predetermined image characteristic exists in the ROI extracted by the extraction means 13; and creation means 15 for creating, when the characteristic region exists, an output image by converting the resolution so that the characteristic region is confined to an image size to be output, and occupies the image by a predetermined ratio or more.
