Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems struggle to appropriately control camera apparatus direction in imaging rooms with variable setups, such as those using both standing and supine position imaging tables, as existing techniques assume fixed positions of radiation generating and detecting apparatuses.
Innovation Solution
A radiation imaging system with a camera control apparatus that includes a recognition unit to identify the imaging location and a setting unit to adjust camera parameters, ensuring accurate video recording of radiation imaging procedures by determining the optimal camera direction and magnification based on the recognized location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera apparatus is controlled using fixed position assumptions, then the control method is simple, but the camera cannot appropriately record imaging procedures in imaging rooms with variable setups (standing/supine tables)
Solution Approach 1:
The system performs preliminary actions by pre-storing correspondence relationships between imaging locations and camera parameters before actual imaging occurs. The recognition unit identifies the imaging location, and the setting unit retrieves pre-configured camera parameters from storage, eliminating the need for complex real-time calculations while adapting to different imaging setups.
Solution Approach 2:
The system changes camera parameters (direction, magnification) based on the recognized imaging location. By storing multiple sets of camera parameters corresponding to different imaging locations and selecting the appropriate parameters dynamically, the system adapts to variable imaging room configurations without requiring complex control algorithms.
2Measurement precision
If the camera apparatus direction is not adjusted according to imaging location, then the control system is simple, but the video image quality and recording accuracy deteriorate
Solution Approach 1:
The system pre-calculates and stores optimal camera parameters (direction, magnification) for various imaging locations before actual use. When imaging occurs, the recognition unit identifies the location and the setting unit retrieves the pre-computed parameters, ensuring accurate video recording without complex real-time processing.
Solution Approach 2:
The system creates a copy of the radiation imaging system's spatial configuration information and uses it to control the camera apparatus. By storing correspondence relationships between imaging locations and camera settings, the system replicates the optimal viewing configuration for each imaging scenario.
3Adaptability or versatility
If the system assumes fixed positions for radiation generating and detecting apparatuses, then the imaging system is simple, but it cannot handle imaging rooms with multiple imaging tables and variable configurations
Solution Approach 1:
The recognition unit provides feedback by identifying the actual imaging location based on detected position information. This feedback is then used by the setting unit to select appropriate camera parameters, creating a closed-loop system that adapts to the actual imaging configuration rather than assuming fixed positions.
Solution Approach 2:
The system introduces an intermediary information layer (correspondence relationship data) that bridges the radiation imaging system and camera control system. This intermediary stores the mapping between imaging locations and camera parameters, enabling the system to handle variable configurations without direct complex interactions between all components.

AI summary
There is provided a mechanism that enables a camera apparatus to record an appropriate video image relating to circumstances in which radiation imaging is performed in an imaging room. A radiation imaging system includes a radiation generating apparatus configured to generate radiation toward an object, a radiation detecting apparatus configured to detect, as an image signal, the radiation incident thereto, a camera apparatus configured to record a video image relating to circumstances in which radiation imaging is performed using the radiation in an imaging room, and a camera control apparatus configured to control the camera apparatus. The camera control apparatus recognizes an imaging location at which the radiation imaging is performed in the imaging room, and sets a parameter of the camera apparatus in accordance with the recognized imaging location.
