X-ray Imaging System Angular Dose Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging systems struggle to easily determine the appropriate imaging unit angle to avoid localized increases in X-ray dose on the patient's body surface, as the dose displayed on three-dimensional models does not allow for precise identification of low-dose angles.
Innovation Solution
An X-ray imaging system and method that calculate and display the dose in each angular region partitioned by predetermined intervals of the imaging unit angle, using a dose calculation processing unit to associate imaging unit angles with a three-dimensional virtual model and display an angular dose image to identify dose magnitudes in each region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the dose is displayed on a three-dimensional model, then the dose distribution can be visualized, but it becomes difficult to concretely determine the appropriate imaging unit angle to avoid localized high dose
Solution Approach 1:
The patent divides the angular range into multiple discrete angular regions (e.g., 0-15 degrees, 15-30 degrees, etc.) and calculates the cumulative dose for each region. This segmentation transforms the continuous dose distribution into discrete, easily comparable values, allowing operators to quickly identify which angular region has the lowest cumulative dose and select that imaging unit angle accordingly.
2Object-affected harmful factors
If the imaging unit angle is changed to avoid localized dose increase, then the skin dose can be reduced, but the operator cannot easily determine which angle to select
Solution Approach 1:
The patent pre-calculates and stores the cumulative dose for each angular region before the actual imaging procedure. This preliminary calculation allows the operator to view the pre-computed angular dose information and make an informed decision about which angle to select, rather than having to calculate or guess the dose distribution during the procedure.
3Measurement precision
If a three-dimensional model is used to display dose, then spatial dose distribution is visualized, but the connection between imaging unit angle and dose is not direct
Solution Approach 1:
The patent extracts the angular dose information from the three-dimensional dose distribution model and presents it as a separate, simplified table or list showing cumulative dose for each angular region. This extraction separates the complex 3D visualization from the practical angular selection task, providing a direct and simple reference for operators without requiring them to interpret complex spatial models.

AI summary
This X-ray imaging system is equipped with a dose calculation processing unit and a display unit. As described above, the dose calculation unit calculates the dose in each of a plurality of angular regions partitioned at each predetermined angular interval of the imaging unit angle, based on the dose distribution on the surface of the virtual model and the imaging unit angle associated with the surface of the virtual model. The display unit is configured to display an angular dose image capable of identifying the magnitude of the calculated doses in each of the plurality of angular regions.
