Solution Overview
Problem
Current X-ray imaging systems face significant display delays due to lower wireless data transmission rates and the need for image enlargement processing, which can hinder detailed diagnosis and increase imaging cycle times, especially in environments without dedicated networks.
Innovation Solution
An X-ray imaging apparatus with an image combining unit, mode selection unit, and control unit that allows for switching between speed priority and resolution priority modes to manage image enlargement processing based on the selected mode, ensuring timely display and high-resolution images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used for transmitting image data, then portability and operability are improved, but transmission rate decreases causing display delay
Solution Approach 1:
The image data is divided into multiple divided images for sequential transmission and reception. This segmentation allows the system to receive and process images in chunks over wireless communication, reducing the impact of lower transmission rates on overall display timing while maintaining portability.
Solution Approach 2:
The system performs preliminary actions by receiving and storing divided images in advance before they are fully transmitted. This allows the imaging apparatus to prepare for subsequent imaging operations while waiting for complete image data, reducing idle time and improving operational efficiency.
2Speed
If image enlargement processing is performed on sampled reduced images, then display speed is improved, but image quality deteriorates for detailed diagnosis
Solution Approach 1:
The system dynamically adjusts the combining method based on the selected mode (speed priority or resolution priority). When resolution priority is selected, the combining method is optimized to maintain high image quality for detailed diagnosis, whereas speed priority mode uses methods that favor faster processing. This dynamic adaptation resolves the contradiction between display speed and image quality.
3Reliability
If all images are received before subsequent imaging preparation, then image completeness is ensured, but imaging cycle time increases
Solution Approach 1:
The system performs preliminary actions by receiving and storing divided images in advance before they are fully transmitted. This allows the imaging apparatus to prepare for subsequent imaging operations while waiting for complete image data, reducing idle time and improving operational efficiency without compromising image completeness.
Solution Approach 2:
The system maintains continuity of useful action by enabling overlapping operations: while receiving divided images, the apparatus simultaneously performs imaging preparation and other useful actions. This eliminates idle waiting time and reduces the overall imaging cycle time while ensuring complete image reception before final processing.
4Manufacturing precision
If higher resolution imaging is implemented, then diagnostic accuracy is improved, but transmission time increases due to larger data size
Solution Approach 1:
High-resolution image data is divided into multiple smaller divided images for sequential transmission. This segmentation reduces the burden on wireless transmission channels, allowing high-resolution images to be transmitted and received incrementally without excessive delays, while maintaining the diagnostic quality of the final combined image.

AI summary
An X-ray imaging apparatus includes an image combining unit configured to sequentially combine divided and transmitted images, a mode selection unit configured to select one of a speed priority mode and a resolution priority mode, and a control unit configured to, if image enlargement is instructed before all the images are received, perform control to change a combining method used for the image combining unit depending on the mode selected by the mode selection unit.
