Mobile Radiography Control Unit for Rapid Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiographic image capturing systems in medical settings face inefficiencies due to the need for radiologists to frequently switch between controlling the radiation source and image capturing apparatus, leading to increased workload and delayed procedures during interruptions or changes in imaging conditions.
Innovation Solution
A radiographic image capturing system with a mobile apparatus that can be moved close to the subject, allowing for rapid switching between a control apparatus and a mobile control unit, enabling the doctor or radiologist to adjust image capturing conditions and patient positioning without needing to return to a distant console.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the control apparatus is placed away from the patient in a preparation room, then the radiologist can operate the console remotely, but the radiologist's workload increases and the ability to rapidly change image capturing conditions deteriorates
Solution Approach 1:
The control system is segmented into two parts: a fixed control apparatus in the preparation room and a mobile apparatus that can be positioned near the patient. The mobile apparatus includes a display unit and operation unit that can be moved close to the patient, allowing the radiologist to quickly adjust imaging parameters without returning to the distant console, thus resolving the contradiction between remote operation safety and operational efficiency
2Manufacturing precision
If the radiologist moves between the console and the patient to perform positioning and adjust conditions, then the patient can be properly positioned and conditions changed, but the time required for procedures increases and productivity decreases
Solution Approach 1:
The mobile apparatus is designed to be dynamically movable between positions near the patient and the preparation room. During fluorography interruptions, the mobile apparatus can be quickly positioned near the patient to perform positioning adjustments and change imaging conditions, then returned to the preparation room. This dynamic positioning capability maintains both positioning accuracy and procedural efficiency by eliminating the need for repeated trips between fixed locations
3Ease of operation
If the mobile apparatus is used close to the patient, then the radiologist can rapidly adjust conditions and positioning, but the device complexity increases due to the need for switching between control apparatuses
Solution Approach 1:
The mobile apparatus is designed with multi-functionality to control both the radiation source and the radiographic image capturing apparatus. It includes a display unit for showing imaging parameters and an operation unit for adjusting them, along with a communication unit that enables it to function as a remote control interface. This universal design allows a single mobile device to perform multiple control functions, reducing the need for separate specialized devices and thereby managing system complexity while maintaining ease of operation

Data Source
AI summary
This radiography system has a switching processing unit that switches the device that controls a radiation source and a radiography device to a control device or a portable apparatus. In a case where penetrative imaging has started, the switching processing unit switches the device that controls the radiation source and the radiography device from the control device to the portable apparatus.
