Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indexes are arranged at appropriate positions in the irradiation field for easy discrimination, then the order determination becomes easier, but the indexes overlap with object structures making recognition difficult
Solution Approach 1:
The patent introduces a position acquiring unit as an intermediary that captures positional information of the radiation imaging apparatus before photography. This positional information serves as a mediator to determine the connection order of images, eliminating the need to visually recognize indexes in the captured images. The position acquiring unit translates physical positions into usable data for order determination, resolving the contradiction between easy operation and detection difficulty.
2Area of stationary object
If multiple radiation imaging apparatuses are arranged to capture long-length regions, then the observation coverage increases, but the complexity of determining the correct connection order increases
Solution Approach 1:
The patent applies preliminary action by acquiring positional information of each radiation imaging apparatus before the actual photography process. The position acquiring unit captures the positions in advance, and this pre-acquired information is stored and later used by the composition processing unit to automatically determine the connection order. This preliminary capture of positional data simplifies the overall process complexity despite using multiple apparatuses for extended coverage.

AI summary
A radiographing system includes a plurality of radiation imaging apparatuses and a composition processing unit which composites a plurality of radiation images acquired from the plurality of radiation imaging apparatuses to generate a long-length image. Each of the radiation imaging apparatuses includes a radiation detecting panel which has a plurality of pixels arrayed in a two-dimensional matrix and converts radiated radiation into an image signal, and a position acquiring unit which acquires positional information by communicating with an external apparatus. A position deciding unit decides an order, in which the plurality of radiation images to be composited by the composition processing unit are composited, based on the positional information acquired by the position acquiring unit.
