Innovation Solution
An RF head coil with integrated audio reproduction system featuring flexible inserts and lateral access, allowing easy positioning of audio outputs and inserts between the patient's ears, eliminating the need for separate headsets and enhancing acoustic transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional in-ear audio headsets with separate power and data leads are used, then audio communication functionality is achieved, but the device complexity increases and ease of operation deteriorates due to uncomfortable positioning and space occupation in the examination zone
Solution Approach 1:
The audio reproduction system is merged with the RF head coil structure. The audio outputs are integrated into the head coil's receiver elements, eliminating the need for separate in-ear headsets and their associated power and data leads. This integration reduces device complexity while maintaining audio communication functionality.
Solution Approach 2:
The RF head coil is designed to serve multiple functions: it provides both magnetic resonance signal reception and audio reproduction capabilities. The receiver elements of the head coil are utilized as audio outputs, allowing the same structure to perform dual roles without requiring additional dedicated components.
2Ease of operation
If mechanical manipulators are used to position earpieces, then audio delivery is achieved, but the device complexity increases and ease of operation deteriorates due to limited access to the patient's ears
Solution Approach 1:
The audio outputs are merged with the head coil structure itself, eliminating the need for separate mechanical manipulators. The receiver elements of the head coil are directly utilized as audio outputs, simplifying the positioning process and improving access to the patient's ears.
Solution Approach 2:
The complex mechanical manipulator system is extracted and removed from the design. Instead of using separate manipulators to position earpieces, the audio functionality is directly integrated into the head coil, which already has the capability to be positioned around the patient's head.
3Adaptability or versatility
If separate power and data leads are provided for audio headset, then audio communication functionality is achieved, but the device complexity increases
Solution Approach 1:
The audio communication functionality is merged with the existing head coil structure. The receiver elements serve dual purposes as both MRI signal receivers and audio outputs, eliminating the need for separate power and data leads while maintaining full audio communication capability.
Solution Approach 2:
The head coil's receiver elements are designed to perform multiple functions: receiving magnetic resonance signals and delivering audio signals. This multi-functionality allows the system to provide audio communication without requiring additional dedicated hardware components.

AI summary
An RF head coil for acquisition of magnetic resonance signals from a patient's head according to the invention comprising an examination volume to receive the patient's head. Receiver elements are located around the examination volume and configured to provide a lateral access into the examination volume. An audio reproduction system with one or more audio outputs is integrated in the RF head coil. One or more flexible inserts fit between the integrated audio output(s) and the patient's ear position. When the patient's head to be examined is positioned in the RF head coil, the flexible inserts may be positioned along the lateral direction between the integrated audio outputs and the patient's outer ear.
