Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray diagnosis systems face challenges in selecting optimal X-ray tube tracks for tomosynthesis imaging, leading to artifacts that obstruct the observation of examined sites, making it difficult to accurately determine appropriate tracks during the imaging process.
Innovation Solution
The X-ray diagnosis apparatus includes processing circuitry that acquires a two-dimensional X-ray image of the patient and generates processed images by performing image processing corresponding to potential X-ray tube tracks, allowing operators to select the most appropriate track based on predicted artifacts and acquisition time, thereby reducing radiation exposure and improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple potential X-ray tube tracks are evaluated through actual imaging trials, then the optimal track can be selected, but the radiation exposure increases and acquisition time extends
Solution Approach 1:
The system performs preliminary image processing simulations for multiple potential tracks before actual imaging. By generating predicted artifact images and evaluation results in advance, the system enables operators to select the optimal track without conducting multiple actual imaging trials, thus reducing acquisition time while maintaining selection accuracy.
Solution Approach 2:
The system creates simulated copies of potential imaging results through image processing for each candidate track. These simulated images replicate the expected artifacts and image quality for each track option, allowing operators to evaluate and compare tracks virtually before committing to actual imaging, thereby avoiding unnecessary radiation exposure and time consumption.

3Adaptability or versatility
If operators manually determine the X-ray tube track during imaging, then flexibility is maintained, but the complexity of operation increases and artifacts may obstruct observation
Solution Approach 1:
The system generates simulated images showing predicted artifacts for each potential track, allowing operators to visually evaluate track options without complex manual calculations or trial-and-error imaging. This maintains operational flexibility while simplifying the decision-making process through intuitive visual comparison.
Solution Approach 2:
The system introduces an intermediate evaluation step that processes potential tracks and presents them to operators in an easily comparable format. This intermediary processing layer translates complex imaging parameters into visual predictions, reducing operational complexity while preserving the ability to select from multiple track options.
4Productivity
If a single X-ray tube track is used for tomosynthesis imaging, then the acquisition time is reduced, but artifacts may obstruct the observation of examined sites
Solution Approach 1:
The system performs preliminary image processing to predict artifacts for multiple potential tracks before actual imaging. This allows the selection of a single optimal track that minimizes artifacts, achieving both fast acquisition and high image quality without requiring multiple imaging trials.
Solution Approach 2:
The system creates simulated images showing predicted artifacts for each candidate track, enabling operators to select the single best track that will produce the highest quality image with minimal artifacts. This virtual evaluation ensures optimal image quality is achieved with a single imaging pass, maintaining both speed and reliability.

AI summary
An X-ray diagnosis apparatus according to an embodiment includes processing circuitry configured: to acquire a two-dimensional X-ray image of an examined subject imaged in a first imaging process; to designate at least one track on which an X-ray generator is to move in a second imaging process to be performed after the first imaging process; and to perform a predicting process of predicting, on the basis of the two-dimensional X-ray image and the track, an artifact that is to occur when the second imaging process is performed by using the track.
