Radiation Fluoroscopy Imaging Apparatus Remote Field Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in the operation room struggle to accurately confirm the X-ray radiation field during transitions from X-ray fluoroscopy to X-ray imaging, leading to difficulties in adjusting the imaging range correctly.
Innovation Solution
An X-ray fluoroscopy imaging apparatus with a display element in the operation room that shows the radiation field acquired by a detector, and a control element that adjusts the collimator-leaves' aperture for both fluoroscopy and imaging modes, allowing operators to confirm and adjust the radiation field effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a collimator lamp is used to check the X-ray radiation field in the examination room, then the operator can check the radiation field when present in the examination room, but the operator cannot accurately check the radiation field when located in the operation room
Solution Approach 1:
The patent creates a visual copy of the radiation field by projecting light from the collimator lamp through the collimator-leaves aperture onto a screen or surface. This light projection replicates the X-ray radiation field geometry, allowing operators in the operation room to view and confirm the imaging range remotely without being physically present in the examination room where the actual X-ray source is located.
2Measurement precision
If the operator must adjust the imaging range again after switching from fluoroscopy to imaging, then the radiation field can be accurately set, but time is lost due to readjustment operations
Solution Approach 1:
The system performs preliminary action by maintaining the collimator-leaves aperture settings from fluoroscopy mode and using the light projection to pre-confirm the imaging range before actual X-ray imaging begins. The operator can verify the radiation field geometry in advance using the visible light projection, ensuring the aperture is correctly positioned before switching to imaging mode, thereby eliminating the need for readjustment and saving time.
3Adaptability or versatility
If the collimator-leaves aperture is changed for imaging while performing fluoroscopy, then the imaging range can be set, but the fluoroscopy field of view is disrupted
Solution Approach 1:
The light projection serves as an intermediary that allows the operator to visualize and adjust the collimator-leaves aperture settings for imaging mode without disrupting the ongoing fluoroscopy. The light projection overlay enables simultaneous monitoring of both fluoroscopy field and intended imaging field, allowing smooth transition between modes while maintaining field stability through visual guidance rather than abrupt mechanical changes.

AI summary
An X-ray fluoroscopy imaging apparatus that confirms the radiation field of a radiation imaging when an operator performs an examination in an operation room. A collimator 12 has a plurality of collimator-leaves 61 positioned and forming a first X-ray radiation field E1 while performing an X-ray fluoroscopy. The apparatus allows an operator, in an operating room distant from an imaging room, to operate an aperture change to confirm the radiation field and each of the collimator-leaves 61 shifts to a position where the X-ray radiation field is reduced to a smaller dimension field E2. Visualizing a displayed X-ray image allows the operator to confirm reaching the radiation field E2.
