Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiography apparatuses with a radiation source and radiography unit supported by a single arm face inconvenience in adjusting positions for imaging directions other than the aligned direction, particularly when imaging objects like bolts inserted into the body, requiring frequent movement or inclination of the arm.
Innovation Solution
A radiography apparatus with a radiation generation unit, a support member, a radiography unit, an imaging direction designation unit, and a radiation source selection unit, allowing for easy adjustment of imaging directions by designating the desired imaging direction and selecting the appropriate radiation source, with input options through operating units and display units for operator convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the radiation source and radiography unit are supported by one arm with fixed relative positions, then alignment adjustment is not needed, but imaging from directions other than the aligned direction requires frequent movement or inclination of the arm
Solution Approach 1:
The radiation generation unit is divided into multiple independent radiation sources arranged at different positions and orientations. Each radiation source can be independently selected and activated, allowing imaging from multiple directions without moving the entire arm assembly. This segmentation enables flexible imaging directions while maintaining the fixed support structure.
Solution Approach 2:
The radiation generation unit is designed with multiple radiation sources that can serve different imaging direction requirements. By selecting different radiation sources from the plurality, the system can perform imaging from various directions using the same support arm, making the system universally applicable for multiple imaging scenarios without requiring physical repositioning.
2Adaptability or versatility
If multiple radiation sources are used to enable imaging from multiple directions, then imaging direction flexibility is improved, but the complexity of the radiation generation unit increases
Solution Approach 1:
Multiple radiation sources are integrated into a single radiation generation unit that is supported by one arm. The radiation sources are arranged in a compact configuration where they share common support structures and control systems. This merging approach allows multiple imaging directions to be achieved while minimizing the increase in overall system complexity through shared components and unified control.
Solution Approach 2:
The system employs dynamic selection of radiation sources based on the desired imaging direction. Rather than having all sources active simultaneously or requiring mechanical reconfiguration, the control system dynamically selects and activates the appropriate radiation source for each imaging task, optimizing system complexity by keeping only the necessary source active at any given time.

AI summary
A radiography apparatus includes a radiation generation unit that has a plurality of radiation sources generating radiation toward a subject, a C-arm that supports the radiation generation unit in a first end portion as one end, a radiography unit that is provided in a second end portion as the other end of the C-arm to face the radiation generation unit and images the subject using radiation, an imaging direction designation unit that designates an imaging direction of the subject, and a radiation source selection unit that selects the radiation source for use in imaging among the plurality of radiation sources using the designation of the imaging direction.
