Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional x-ray apparatuses, such as C-arm and computer tomography systems, pose challenges due to mechanical components obstructing access during medical interventions and requiring significant space, limiting ease of use and safety for both medical personnel and patients.
Innovation Solution
An x-ray apparatus with a movable x-ray source and detector, where the source moves in one plane and the detector in a parallel, non-coinciding plane, allowing for two-dimensional projections from various angles without mechanical obstruction, enabling improved access and reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a C-arm or computer tomography apparatus is used to determine spatial presentations, then projection datasets can be recorded from different projection directions, but mechanical components (C-arm or gantry) obstruct access to the object under examination and require significant space
Solution Approach 1:
The apparatus is divided into two independent segments: the x-ray source that can be moved in a first plane, and the x-ray detector that remains stationary in a second plane. This segmentation allows the source to access different projection directions without requiring a mechanical C-arm structure that would obstruct access to the examination area.
Solution Approach 2:
The invention transitions from the traditional C-arm configuration where source and detector are rigidly connected in three-dimensional space to a system where the source moves in one plane (first plane) and the detector is positioned in a parallel second plane. This dimensional separation eliminates the need for mechanical arms extending into the examination space.
2Measurement precision
If a C-arm or computer tomography apparatus is used to record projection datasets, then spatial presentations can be determined, but the apparatus requires significant space and mechanical components are disposed between medical personnel and the object under examination
Solution Approach 1:
By separating the x-ray source and detector into independent components operating in different planes, the system eliminates the need for a large mechanical C-arm structure or gantry. The source can be moved in a compact first plane while the detector remains in a parallel second plane, significantly reducing the spatial footprint of the apparatus.
Solution Approach 2:
The invention extracts the mechanical C-arm or gantry structure from the system entirely. Instead of using a rigid mechanical connection between source and detector, the system uses independent movement of the source in one plane with a stationary detector in another plane, removing the space-consuming mechanical framework.
3Productivity
If the x-ray source and detector are mechanically connected as in C-arm apparatus, then they can record projections together, but strain lag occurs due to the inherent weight of the device components requiring frequent calibration
Solution Approach 1:
The system segments the source and detector into independent units without mechanical connection. The source moves freely in the first plane while the detector remains stationary in the second plane, eliminating mechanical strain and the need for calibration while maintaining synchronized projection recording through independent positioning control.
4Measurement precision
If conventional C-arm apparatus is used, then spatial presentations can be determined, but the apparatus requires mechanical components that complicate the system structure
Solution Approach 1:
The invention removes the complex mechanical C-arm or gantry structure entirely. The system uses a simple configuration where the x-ray source moves in one plane and the detector is positioned in a parallel plane, eliminating mechanical linkages, joints, and associated complexity while maintaining the ability to record projections for spatial reconstruction.
