Ultrasound Probe ID Verification via Binary State Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasound diagnostic apparatuses face issues with proper probe control and safety due to erroneous recognition of unauthorized or unguaranteed ultrasound probes, leading to malfunctions, potential injuries, and diagnostic errors when such probes are connected.
Innovation Solution
The implementation of a consistency determination function within the ultrasound diagnostic apparatus, which converts electrical states from the probe's binary state generation unit into a probe ID and compares it with stored probe identification information, outputs warnings and prevents access to the ultrasound transmission/reception unit if inconsistencies are found, ensuring only authorized probes are used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ultrasound diagnostic apparatus uses a detachable connector with hard wires to detect probe ID, then the apparatus can selectively use different ultrasound probes for various diagnostic targets, but the apparatus may erroneously recognize unauthorized or unguaranteed probes leading to malfunctions and safety issues
Solution Approach 1:
The system performs preliminary verification of the probe ID against stored reference information before allowing the probe to be used. The determination unit compares the detected probe ID with reference probe ID information stored in the storage unit, and only permits ultrasound transmission/reception when consistency is confirmed, preventing unauthorized probes from causing malfunctions or safety issues
Solution Approach 2:
The system implements a feedback mechanism where the determination unit continuously monitors and compares the probe ID detected via hard wires with reference information, providing real-time verification. When inconsistency is detected, the system provides feedback to prevent probe usage, ensuring reliable distinction between authorized and unauthorized probes
2Ease of operation
If the apparatus accepts any probe with a detectable ID, then the ease of operation is improved, but the risk of diagnostic errors and injuries increases
Solution Approach 1:
The system performs preliminary verification of probe authorization before enabling diagnostic operations. The determination unit checks consistency between the detected probe ID and reference information stored in the storage unit, ensuring that only authorized probes can be used for diagnosis, thereby preventing diagnostic errors and potential injuries while maintaining ease of operation for legitimate probes
Solution Approach 2:
The determination unit acts as an intermediary between the probe connection and the ultrasound transmission/reception functions. It verifies probe authorization by comparing probe ID with reference information, and only permits the ultrasound functions to operate when verification succeeds, thus preventing harmful effects from unauthorized probes while allowing convenient operation with authorized ones

AI summary
An ultrasound diagnostic apparatus includes an ultrasound probe with transducers, memory storing probe identification information and binary state generation unit generating a binary electrical state corresponding to a probe identifier, probe identifier conversion unit converting the electrical state into the probe identifier, read unit reading the probe identification information from the memory, determination unit determining consistency between the probe identifier after conversion and the probe identification information read from the memory, and warning output unit outputting a predetermined warning if the probe identifier is inconsistent with the probe identification information.
