X-ray Tube Control Unit Delayed Preparation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging apparatuses face prolonged preparation times due to voice guidance delays, leading to increased filament heating and rotating anode abrasion, which shortens the lifespan of these components.
Innovation Solution
An X-ray imaging apparatus with a control unit that initiates X-ray tube preparation only after a calculated delay (t1) following the start of voice guidance, where t1 is determined by subtracting the preparation time (t3) from the voice guidance time (t2), allowing for flexible selection of t1, including setting it to zero, and optional use of the voice guidance unit based on anatomical programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice guidance is started when the imaging preparation button is pressed, then the subject receives breath-holding instructions, but the preparation time of the imaging unit is prolonged
Solution Approach 1:
The X-ray tube preparation is started in advance before the voice guidance ends, specifically initiating the filament heating and anode rotation before the breath-holding instruction is complete. This preliminary action ensures that the imaging unit is ready by the time imaging should occur, eliminating the need to wait for voice guidance to finish while still providing complete voice instructions to the subject.
2Duration of action of moving object
If the X-ray tube preparation is executed for a long time, then the voice guidance can be complete, but the filament life is reduced due to continuous heating
Solution Approach 1:
The filament heating and anode rotation are initiated preliminarily before the voice guidance conclusion, allowing these preparation processes to overlap with the voice guidance period. This ensures that by the time the subject finishes breath-holding, the X-ray tube is already prepared, eliminating unnecessary extended heating time and preserving filament life.
3Productivity
If the rotating anode rotates continuously for a long time, then the X-ray imaging preparation is complete, but the bearing wears out faster
Solution Approach 1:
The rotating anode is set into rotation in advance during the voice guidance period, specifically starting the rotation before the breath-holding instruction ends. This preliminary rotation ensures the anode is ready for imaging without requiring continuous rotation beyond what is necessary, thereby reducing unnecessary bearing wear while maintaining imaging readiness.

AI summary
When a first-stage push-button switch of an operation unit (2) is pressed, an X-ray imaging control unit (72) transmits a signal A for starting voice guidance to a signal output unit (73) for a voice guidance unit as well as a signal B for starting preparation of X-ray imaging to an X-ray tube control unit (71). At this time, when the pushing operation of the push-button switch is performed, the X-ray imaging control unit (72) immediately transmits the signal A for starting the voice guidance to the signal output unit (73) for the voice guidance unit but transmits the signal B for starting the X-ray imaging after a time t1 has elapsed. The time t1 is a time calculated by subtracting a time t3 required for preparing an X-ray tube (42) for performing X-ray imaging from a time t2 required for the voice guidance.
