Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CT devices face challenges in data transmission due to increased data volumes from advanced detectors, with slip ring systems being susceptible to wear and contamination, and wireless transmission being hindered by detector housings.
Innovation Solution
A detector apparatus with integrated radio units and antennas for wireless data transmission, housed in a structure with recesses to facilitate communication through the housing, allowing for compact design and reduced cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless data transmission is implemented through the housing, then data transmission reliability is improved, but the housing structure becomes more complex due to recess requirements
Solution Approach 1:
The patent extracts the radio antenna from the enclosed housing space by creating a recess in the housing wall. This allows the antenna to be positioned where it can transmit wireless signals effectively while still being partially protected by the housing structure. The antenna is taken out of the full enclosure to resolve the contradiction between shielding and transmission.
Solution Approach 2:
The housing structure is modified locally at specific positions where radio antennas need to transmit signals. Instead of changing the entire housing structure, recesses are created only in the necessary locations to allow wireless transmission while maintaining the protective enclosure elsewhere. This local modification resolves the contradiction by providing transmission paths only where needed.
2Reliability
If slip ring systems are used for data transmission, then data transmission path is established, but wear and contamination performance losses occur
Solution Approach 1:
The patent replaces the mechanical slip ring system with a wireless transmission system using radio antennas. This substitution eliminates the mechanical contact and rotating connections that cause wear and contamination, while maintaining reliable data transmission from the rotating detector to the stationary receiver.
3Object-affected harmful factors
If detector housing provides electromagnetic shielding, then electromagnetic protection is improved, but radio transmission capability deteriorates
Solution Approach 1:
The radio antenna is extracted from the fully enclosed shielded housing by creating a recess. This allows the antenna to access the external environment for wireless transmission while the rest of the housing maintains electromagnetic shielding for the detector components. The shielding and transmission functions are separated spatially.
Solution Approach 2:
The housing structure has different properties in different locations: most of the housing provides electromagnetic shielding, while specific recess areas provide radio transmission capability. This local differentiation of housing properties resolves the contradiction between shielding and transmission.

AI summary
A detector apparatus for a computed tomography device includes: at least one detector module having a sensor configured to detect measurement signals; at least one radio unit assigned to the at least one detector module, the radio unit having at least one radio antenna for wireless data transmission of the detector signals; and a housing that at least partially encloses the at least one detector module. The housing has a recess for the at least one radio antenna, relative to which the at least one radio antenna is arranged, so that wireless data transmission of the detector signals through the housing is enabled.
