Ultrasonic Diagnostic Device Cumulative Scan Time Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic diagnostic devices do not display the cumulative scan time, which is a critical factor in adhering to the ALARA principle, potentially leading to improper user guidance and excessive ultrasound exposure.
Innovation Solution
An ultrasonic diagnostic device and control method that include a display to show a cumulative scan time, allowing users to adhere to the ALARA principle by indicating the scannable time for each object or diagnostic subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional ultrasonic diagnostic devices display only mechanical index and thermal index, then the device complexity is low, but the information completeness for ALARA compliance is insufficient
Solution Approach 1:
The patent segments the scan time information by dividing it into cumulative scan time across all diagnostic subjects and individual scan time for each specific diagnostic subject. This segmentation allows comprehensive time tracking while organizing information in a structured, manageable way that enhances ALARA compliance without overwhelming the user interface.
Solution Approach 2:
The patent adds a temporal dimension to the existing display by introducing time-based indicators (cumulative scan time and per-subject scan time) to the traditional mechanical and thermal index displays. This multi-dimensional approach provides comprehensive safety information without significantly increasing interface complexity.
2Reliability
If cumulative scan time is displayed for all diagnostic subjects, then ALARA compliance is improved, but the device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms by displaying real-time scan time information to users. The cumulative scan time and individual diagnostic subject scan times are continuously updated and presented, enabling users to make informed decisions about scanning duration and adhere to ALARA principles through immediate visual feedback on exposure levels.

AI summary
Disclosed is a control method of an ultrasonic diagnostic device, which comprises a display configured to display an ultrasonic image corresponding to a scan area scanned by a probe, including identifying an object included in the scan area, determining a diagnostic subject based on at least one of the object or a user input received from an input interface, determining a scannable time for each object or diagnostic subject, and displaying an indicator for displaying the scannable time on the display.
