Solution Overview
Problem
Conventional ultrasonic diagnostic apparatuses lack the capability to easily compare and display desired past images alongside live images during procedures like tumor puncture and treatment effect determination, limiting their effectiveness in medical treatments.
Innovation Solution
The ultrasonic diagnostic apparatus includes an image acquisition mode for registering past images and an image comparison mode for displaying selected past images alongside live images, allowing for matching of observation angles, magnification, and positional relationships, enabling effective comparison and treatment monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ultrasonic diagnostic apparatuses use only dual display function and patient browser function, then the device complexity remains simple, but the ease of operation for comparing arbitrary past images with live images is poor
Solution Approach 1:
The display control unit is enhanced to provide multiple display modes (dual display mode, patient browser mode, and image comparison mode) within a single apparatus. The image comparison mode allows selection of arbitrary past images from storage and displays them alongside live images, making the apparatus universally capable of various image comparison tasks without requiring separate dedicated devices for each function.
2Productivity
If the apparatus displays multiple images simultaneously for comparison, then the productivity of medical diagnosis is improved, but the ease of operation becomes more difficult due to multiple functions
Solution Approach 1:
The apparatus provides dynamic switching between different display modes (dual display, patient browser, and image comparison modes) based on operational needs. The image comparison mode dynamically allows selection of arbitrary past images from storage and displays them alongside live images, enabling flexible adaptation to different diagnostic scenarios without requiring complex manual configuration.
3Adaptability or versatility
If the apparatus allows arbitrary image selection and comparison, then the adaptability of the system is improved, but the device complexity increases
Solution Approach 1:
The display control unit is enhanced to provide multiple display modes (dual display mode, patient browser mode, and image comparison mode) within a single apparatus. The image comparison mode allows selection of arbitrary past images from storage and displays them alongside live images, making the apparatus universally capable of various image comparison tasks without requiring separate dedicated devices for each function.

AI summary
In the image acquisition mode, desired past images are registered in an image table. A past image selected from the past images registered in the table is displayed as a reference image together with a live image in a predetermined form. Selecting another image registered in the image table at an arbitrary timing will display another past image upon replacing the reference image.
