Solution Overview
Problem
Establishing reliable and efficient communication between a subject and a radiation medical device is challenging due to individual subject characteristics and changing environmental conditions, leading to potential communication errors and safety risks during medical procedures.
Innovation Solution
A method and device that dynamically select and adjust communication paths between a subject and a radiation medical device in real-time by transmitting test signals through multiple communication methods (audio, visual, tactile, etc.) and assessing responses to determine the most effective communication modality, ensuring continuous and reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication method is used between the subject and the radiation medical device, then the device complexity is reduced, but the reliability of communication deteriorates due to individual subject characteristics and changing environmental conditions
Solution Approach 1:
The system dynamically selects and switches between different communication methods (audio, visual, tactile) based on real-time assessment of subject response and environmental conditions. This dynamic adaptation allows the system to maintain reliable communication while managing complexity through automated decision-making algorithms.
Solution Approach 2:
The communication system is designed to support multiple communication modalities (audio via loudspeaker/microphone, visual via display, tactile via haptic feedback) within a single integrated system. This multi-functionality enables the system to adapt to different subject characteristics and environmental conditions while maintaining a unified control architecture.
2Adaptability or versatility
If multiple communication methods are tested and assessed in real-time, then the adaptability to subject characteristics improves, but the loss of time increases due to additional signal transmission and assessment steps
Solution Approach 1:
The system performs preliminary testing of multiple communication methods at the beginning of the interaction to establish which methods are most effective for the specific subject. This preliminary assessment allows the system to adapt to subject characteristics in advance, reducing the need for continuous switching during critical procedures.
Solution Approach 2:
The system continuously monitors subject responses to communication signals and uses this feedback to automatically adjust and select the most effective communication method. This real-time feedback mechanism enables adaptive communication while minimizing time loss through automated decision-making based on response indicators.
3Reliability
If continuous assessment of subject response is performed, then the safety of the subject improves by detecting communication failures, but the use of energy increases due to ongoing signal transmission and analysis
Solution Approach 1:
The system performs periodic assessment of subject response at strategically chosen intervals rather than continuously, balancing safety monitoring with energy conservation. This periodic approach allows the system to detect communication failures and adapt to changing conditions while reducing overall energy consumption compared to continuous monitoring.

AI summary
A method for establishing and/or changing a communication path between a subject and a radiation medical device (20, 30) in real time during operation of the radiation medical device (20:30). The method comprises providing, by a data processing unit, a set of communication methods between the subject and the radiation medical device, wherein the communication methods of the set of communication methods differ from each other in terms of the used technology (S 10): transmitting, by the data processing unit, at least one test signal to the subject via at least one communication method of the set of communication methods (S20); receiving, by the data processing unit, at least one response signal from the subject in response to the test signal (S30): assessing, by the data processing unit, the at least one response signal by analyzing it and/or the test signal for one or more response indicators indicating whether the subject is responding to the test signal, and to derive an assessing result therefrom (S40): in case the assessing result is positive: selecting, by the data processing unit, the at least one communication method of the set of communication methods for establishing the communication path (S50); in case the assessing result is negative: transmitting, by the data processing unit, at least one further test signal to the subject via at least one further communication method of the set of communication methods, receiving, by the data processing unit, at least one further response signal from the subject in response to the at least one further test signal, assessing, by the data processing unit, the at least one further response signal by analyzing it and/or the test signal for one or more response indicators indicating whether the subject is responding to the test signal, and to derive a further assessing result therefrom, in case the further assessing result is positive, selecting the at least one further communication method of the set of communication methods for establishing the communication path (S60).
