Voice Guidance Synchronization in Medical Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image diagnosing apparatuses face challenges in synchronizing the timing of voice guidance instructions with the respiratory actions of subjects, leading to potential image blurring or artifacts due to varying reaction times and delays, especially in high-aged individuals.
Innovation Solution
An image diagnosing apparatus with a voice guidance unit and a voice output control unit that adjusts the reproduction speed of voice guidance to match the timing of image shooting, ensuring that inhalation, exhalation, and breathing halt instructions align with the subject's respiratory actions, optionally using a respiration sensor to measure and adjust the voice guidance timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the voice guidance reproduction speed is fixed, then the voice output timing is uniform, but the timing between breathing halt instruction and image shooting may lag due to varying subject reaction times
Solution Approach 1:
The patent applies dynamics by making the voice guidance reproduction speed variable rather than fixed. The reproducing speed is dynamically adjusted based on the subject's respiration timing detected by the respiration sensor, allowing the system to adapt to individual differences in respiratory patterns and reaction times while maintaining synchronization between the breathing halt instruction and image shooting timing.
2Device complexity
If the voice guidance is issued with fixed timing, then the instruction delivery is simple, but high-aged subjects may have delayed reaction and cannot halt breathing at the correct timing
Solution Approach 1:
The patent implements feedback by using the respiration sensor to continuously monitor the subject's respiratory timing and using this information to adjust the voice guidance reproduction speed. This closed-loop feedback mechanism ensures that the breathing halt instruction is delivered at the optimal moment for each subject, accommodating variations in reaction time especially for high-aged individuals, while maintaining accurate synchronization with the image shooting timing.
3Reliability
If the reproducing speed of voice guidance is varied to match subject's respiration timing, then the synchronization between voice guidance and image capture is improved, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary element - the respiration sensor - that mediates between the subject's natural respiration and the voice guidance system. The sensor detects respiration timing and provides this information to the voice output control unit, which then adjusts the reproduction speed accordingly. This intermediary approach enables automatic adaptation to individual respiratory patterns without requiring complex manual calibration or direct neural control.

AI summary
With the object of enabling a subject to be imaged at an appropriate timing of shooting, an image diagnosing apparatus for shooting an image of the subject in an imaging space has a voice guidance unit which reproduces and outputs to the subject a prescribed voice guidance and a voice output control unit which causes the output timing of the voice guidance outputted from the voice guidance unit to correspond with the timing of shooting the image of the subject.
