The description focuses on the hardware components and basic signal reception principles of an MRI coil. There is no mention of AI, ML, or any advanced image processing techniques that would typically involve these technologies.
No.
The device is described as a Magnetic Resonance Imaging coil used for diagnostic imaging, not for treatment.
No
The device is a receive-only RF surface coil used to acquire images for foot and ankle imaging. Its output (images) would then be interpreted by a medical professional for diagnosis. It does not provide a diagnosis itself.
No
The device is a physical coil with integrated preamplifiers and associated accessories, clearly indicating it is a hardware device used in Magnetic Resonance Imaging.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The 8ch Foot Ankle Coil is a component of a Magnetic Resonance Imaging (MRI) system. It's a receive-only RF surface coil that receives signals from the patient's foot or ankle within the body during an MRI scan. It does not analyze specimens taken from the body.
- Intended Use: The intended use is for "foot and ankle imaging," which is a diagnostic imaging procedure performed on the patient directly, not on a sample.
Therefore, the device's function and intended use clearly fall outside the scope of In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
8ch Foot Ankle Coil manufactured by RFT is a receive-only RF surface coil designed for use with the SIGNA Pioneer only. 8ch Foot Ankle Coil is indicated to use for foot and ankle imaging. The nucleus excited is hydrogen.
