Table Position Adjustment in Medical Data Acquisition Scanners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical data acquisition scanners require different scanning protocols for various body regions due to varying contrast ratios, making existing protocols incompatible across regions.
Innovation Solution
The method allows for the selection of a single scanning protocol to be applied across different body regions by independently setting the table position based on anatomical information, using two modes of operation: iso-mode for optimal image quality and ref-mode for reduced table movements, where the table position is set relative to a reference position regardless of the isocenter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different scanning protocols are used for different body regions, then image quality is optimized for each region, but device complexity and operational complexity increase
Solution Approach 1:
The patent implements a universal scanning protocol that can be applied to multiple body regions. The control device determines table position based on anatomical information from the selected body region, allowing a single protocol to serve multiple regions without sacrificing image quality. This eliminates the need for region-specific protocol customization.
Solution Approach 2:
The system dynamically adjusts the table position based on the selected body region while maintaining a single scanning protocol. The control device modifies operational parameters (table position) in real-time according to anatomical information, enabling one protocol to adapt to different regions rather than requiring static region-specific protocols.
2Measurement precision
If multiple scanning protocols are maintained for different body regions, then imaging accuracy is preserved, but ease of operation deteriorates
Solution Approach 1:
The patent enables a single scanning protocol to function across multiple body regions. The user simply selects the body region, and the control device automatically determines the appropriate table position, eliminating the need for users to select different protocols for different regions and simplifying the operational workflow.
Solution Approach 2:
The control device automatically determines the table position based on anatomical information from the selected body region without requiring user intervention. The system self-adjusts operational parameters based on the input data, reducing the complexity of user operation while maintaining imaging accuracy.
3Measurement precision
If table position is adjusted for each body region, then imaging precision is improved, but productivity decreases due to increased table movements
Solution Approach 1:
The control device determines the appropriate table position in advance based on anatomical information from the selected body region before the scanning protocol is executed. This preliminary determination optimizes the table position setup, reducing unnecessary adjustments during the examination and improving overall efficiency.
Solution Approach 2:
The single scanning protocol with automatic table position determination based on anatomical information reduces the need for multiple protocol switches and repeated table movements. The system efficiently handles different body regions through one protocol with adaptive positioning, improving examination throughput.

AI summary
In a method and apparatus for adjusting a table position in a medical data acquisition scanner, image data relating to a body region are generated by operation of the medical data acquisition scanner by running a scanning protocol. The scanning protocol is intended to be used independently of the body region that is mapped. An iso-mode, in which a relative position of the body region relative to the isocenter of the medical data acquisition scanner can be set via the table position in accordance with an optimization criterion, and on a ref-mode, in which the table position is set at a predetermined reference position, are provided. A mode of operation is selected from the iso-mode and the ref-mode as dependent on anatomical information relating to the body region and/or a relative position of the body region relative to the isocenter that ensues in the reference position, and before the running of and/or during the running of the selected scanning protocol, the table position is set according to the selected mode of operation.
