Patient Stillness System Using Motion-Adaptive Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conducting imaging scans can be challenging for pediatric patients, leading to unwanted movement that results in artifacts in imaging data, necessitating additional scans, increased radiation exposure, and longer scanning times.
Innovation Solution
A system and method that utilize an electronic device and motion detection system to generate and modify a graphical representation for patients during scans, adverse modification of which occurs if significant motion is detected, to encourage stillness, potentially using a headset or projection system with sensors and a computer system to monitor and manage patient movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pediatric patients undergo imaging scans, then diagnostic imaging is obtained, but patient movement causes artifacts requiring additional scans
Solution Approach 1:
The patent introduces a graphical representation as an intermediary element between the patient and the imaging process. This visual distraction serves as a mediator that occupies the patient's attention, reducing movement without interfering with the actual imaging procedure. The graphical display acts as a buffer that transforms the patient's focus away from the confined scanning environment.
Solution Approach 2:
The system dynamically changes the parameters of the graphical representation based on detected patient motion. When movement is detected, the system modifies characteristics such as the speed, complexity, or content of the graphical display to better engage the patient's attention and encourage stillness, thereby adapting the distraction strategy in real-time.
2Manufacturing precision
If additional scans are performed to compensate for motion artifacts, then image quality is improved, but radiation exposure increases
Solution Approach 1:
The system implements a feedback loop where motion detection sensors continuously monitor patient movement and provide real-time information to the control system. This feedback enables the system to detect motion artifacts early and respond by modifying the graphical representation or alerting operators, preventing the need for additional repeat scans and thereby reducing cumulative radiation exposure.
Solution Approach 2:
The system takes preliminary action by providing visual distraction before motion artifacts can degrade image quality. By engaging the patient's attention with graphical representations during the scan, the system proactively prevents movement rather than reacting to it afterward, thus avoiding the need for additional scans and associated radiation exposure.
3Ease of operation
If motion detection system adversely modifies graphical representation, then patient stillness is encouraged, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating motion detection, real-time graphical modification, and patient engagement capabilities into a single unified platform. The electronic device serves multiple purposes: displaying graphical representations, detecting motion through integrated sensors, and dynamically adjusting the display based on motion feedback, thereby reducing the need for separate independent systems.
Solution Approach 2:
The system performs self-service by automatically detecting patient motion and independently modifying the graphical representation without requiring operator intervention. The closed-loop control system autonomously adjusts distraction parameters based on real-time motion data, reducing the complexity of manual monitoring and adjustment while maintaining effective patient stillness encouragement.
