Remote ICU Radiographic Imaging System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infection control in healthcare settings, particularly in intensive care units, is challenging due to the risk of communicable pathogens. Existing imaging technologies require physical proximity between healthcare providers and patients, increasing the risk of infection and the need for personal protective equipment.
Innovation Solution
A remotely controlled and automated digital radiographic imaging system is deployed in ICU units, featuring a digital radiographic detector in each patient bed and an overhead tube crane mechanism with a collimated x-ray source. This system allows for the remote positioning and firing of the x-ray source, enabling radiographic imaging while maintaining isolation between healthcare providers and patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile x-ray units are used for imaging, then imaging flexibility is improved, but infection risk to healthcare providers increases
Solution Approach 1:
The patent introduces a remote control system as an intermediary between the healthcare provider and the x-ray imaging system. The provider operates the mobile x-ray unit from a remote location through electronic controls, allowing the imaging function to be performed without the provider being in physical proximity to the patient, thus eliminating infection risk while preserving imaging flexibility
Solution Approach 2:
The imaging system is segmented into separate functional components: the x-ray source and detector remain in proximity to the patient for imaging, while the control interface is separated and relocated to a remote position. This segmentation allows the harmful function (radiation source near patient) to be isolated from the operator, while the beneficial function (imaging capability) remains accessible
2Object-affected harmful factors
If personal protective equipment is used, then infection protection is improved, but operational complexity increases
Solution Approach 1:
The patent extracts the protective function from personal equipment (PPE) and relocates it to the environmental design of the imaging system. By providing physical barriers such as shielding walls and controlled access between the provider and patient areas, the system inherently protects the provider without requiring them to don complex PPE, thereby reducing operational complexity
3Manufacturing precision
If physical proximity between provider and patient is maintained, then imaging quality is improved, but staff exposure to pathogens increases
Solution Approach 1:
The patent replaces the mechanical requirement of physical proximity with an electronic control system. Sensors, cameras, and electronic interfaces substitute for direct line-of-sight and physical presence, enabling the provider to acquire and control imaging parameters remotely while maintaining the necessary geometric relationships for high-quality imaging through automated positioning systems
4Object-affected harmful factors
If remote control systems are implemented, then infection isolation is improved, but system complexity increases
Solution Approach 1:
The remote control system is designed with multi-functionality to justify its complexity: it integrates imaging control, patient monitoring, communication capabilities, and environmental control into a single unified interface. This universal system performs multiple functions that would otherwise require separate devices and personnel, thereby managing system complexity through consolidation rather than multiplication of components
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 system effectively isolates healthcare providers from communicable pathogens, reducing the risk of infection and the need for personal protective equipment. It also improves image quality and consistency compared to mobile DR imaging systems, while enabling remote operation to minimize staff exposure.
Implementation Method 1
an x-ray source operable to be selectively positioned relative to each of the patient beds
Data Source
AI summary
A radiographic imaging system may be deployed in an ICU unit of a medical facility that may benefit from isolating patients and health care providers. The radiography system provides a plurality of patient beds each having a digital radiographic detector positioned therein. An x-ray source is operable to be selectively positioned relative to each of the patient beds using a remote control system. The remote control system also controls firing of the x-ray source.
