Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiography apparatuses lack usability improvements, particularly in considering the influence of gravity on the subject and technician operations, with technicians often relying on button instructions for up or down directions and limited consideration for the impact of gravity on imaging.
Innovation Solution
A radiography apparatus equipped with a radiation detector that sets up and displays up and down directions, a detection unit to detect these directions, and a display unit within the housing to show direction information, along with a control unit to manage display based on predetermined conditions such as time, impact, or radiation emission, enhancing technician usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If technicians operate buttons to instruct up or down directions, then the radiography apparatus can capture images in different orientations, but the usability of the technician deteriorates due to manual operation requirements
Solution Approach 1:
The detection unit automatically detects the housing direction and determines the up and down directions of the radiation detector without requiring technician intervention. The system serves itself by using sensors to detect orientation and automatically setting the imaging parameters, eliminating the need for manual button operations while maintaining full adaptability to different imaging orientations
Solution Approach 2:
The detection unit provides real-time feedback about the housing direction to the control unit, which then automatically adjusts the imaging parameters. This feedback mechanism enables the system to self-correct and adapt to different orientations without requiring manual input from the technician, improving both automation and usability
2Loss of information
If direction information is continuously displayed, then the technician can always confirm the orientation, but the device complexity increases due to additional display control mechanisms
Solution Approach 1:
The control unit determines the up and down directions in advance based on detection unit data before imaging begins. This preliminary determination allows the system to prepare the correct orientation information without requiring complex real-time display control mechanisms during the imaging process
Solution Approach 2:
The display unit shows direction information selectively based on specific conditions (such as when the housing direction changes or during critical imaging phases) rather than continuously. This partial display approach maintains sufficient direction information availability while avoiding the complexity of continuous display control systems
3Manufacturing precision
If the apparatus automatically detects and adjusts based on impact or radiation emission, then the imaging accuracy improves, but the device complexity increases due to additional detection and control mechanisms
Solution Approach 1:
The impact detection unit and radiation emission detection functionality are integrated into the existing control unit of the radiography apparatus. By merging these detection capabilities with the existing control system, the patent achieves improved imaging accuracy through automatic impact and radiation emission-based adjustments without proportionally increasing overall device complexity
Solution Approach 2:
The control unit is designed to perform multiple functions: it controls the radiation source, processes images, and now also detects impacts and radiation emission to automatically adjust imaging parameters. This multi-functionality allows a single control unit to handle diverse tasks, improving imaging accuracy while minimizing the need for separate dedicated components that would increase complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus improves technician usability by providing clear direction information, ensuring correct orientation of radiographic images, and allowing for automatic adjustments based on detected impacts or radiation emission, thus enhancing imaging accuracy and efficiency.
Implementation Method 1
a technique of detecting and displaying a direction of gravity in the imaging of a radiographic image is proposed since a state of the organ and a state of a contrast agent are changed by the influence of gravity
