No
The device description focuses on passive antenna technology and the performance studies evaluate standard imaging parameters like SNR and image uniformity, with no mention of AI/ML algorithms or training/test data for such models.
No
The device is described as a diagnostic device extension for an MR system, used to provide images and spectra that may assist in diagnosis, not to treat a condition.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The Head Coil is indicated for use as diagnostic device extension." It also mentions that the images produced "when interpreted by a trained physician yield information that may assist in diagnosis."
No
The device description explicitly states it is a "Head Coil" which is a physical component used in MRI systems, and it describes its function as a "transmit/receive coil" and "passive antenna technology." This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Head Coil is a component of an MRI system. It works by exciting and detecting radiofrequency signals within the patient's head to create images and spectra. It does not analyze samples taken from the patient.
- Intended Use: The intended use clearly states it's for providing images and spectra of the internal structure of the head, which are then interpreted by a physician. This is a diagnostic imaging device, not an in vitro diagnostic test.
Therefore, the Head Coil falls under the category of a medical imaging device, not an IVD.

Intended Use / Indications for Use
The Head Coil is indicated for use as diagnostic device extension for a Philips, Siemens or GE 3.0 T MR system to provide cross-sectional 1H and/or any X nucleus images, spectroscopic images and/or spectra in any orientation of the internal structure of the head of the patient. These images when interpreted by a trained physician yield information that may assist in diagnosis.

Device Description
The Head Coil is used in Magnetic Resonance Imaging and Spectroscopy (MRI, MRS). The Head Coil has been designed to be used on Siemens, Philips or GE 3.0 T MR systems. The Head Coil is a transmit/receive coil to excite and detect radiofrequency (RF) signals of hydrogen (1H) nuclei in combination with either phosphorus (31P), carbon (13C) or sodium (23 Na) nuclei. Excitation of the nuclei is achieved by applying an RF magnetic field. The detected signal is an RF voltage being induced in the Head Coil by the nuclei observed. The Head Coil mainly offers passive antenna technology for linking the MR system to the patient (and reverse).

Summary of Performance Studies
Nonclinical tests were performed on a phantom to evaluate the SUBJECT DEVICE with regard to the applicable imaging parameters Signal to Noise Ratio (SNR) and Image Uniformity. Tests were conducted following NEMA Standards. Moreover and following the principle of reciprocity the transmit efficiency (which is applicable to transmit / receive coils) was compared between SUBJECT DEVICE and PREDICATE DEVICE. Test results show an equivalent or better SNR and Image Uniformity performance of the SUBJECT DEVICE.
ESD-Tests have been performed and successfully passed according to the requirements of IEC 60601-2-33 Ed. 3.2 b:2015, Chapter 202.8.101.
Clinical images were acquired in order to check image quality in vivo. Gradient and spin echo sequences which are typical for diagnosis were applied with standard scan parameters and image orientations (axial, sagittal and coronal). These tests show that the SUBJECT DEVICE provides adequate image quality (SNR, penetration depth, contrast, resolution and robustness against artifacts) as well as scan time and that patient comfort are good.

Equivalency Information
RAPID Biomedical believes that the SUBJECT DEVICE is substantially equivalent to the cleared PREDICATE DEVICE which is described in the following submission:
| DUAL TUNED HEAD COIL 3T | Clearance Number | Date |
|---|---|---|
| 31P/1H Head Coil 3T | ||
| 23Na/1H Head Coil 3T | ||
| 13C/1H Head Coil 3T | K102748 | 2011-05-13 |
Summary of Technological Characteristics of the SUBJECT DEVICE as compared with the PREDICATE DEVICE
The proposed labelling is adjusted compared to the PREDICATE DEVICE with respect to differing MR systems, changes in the currently applicable standards and for better usability.
Overall, the indications for use, the intended use and the coil technology and safety are substantially equivalent.
General Safety and Effectiveness Concerns
The safety and performance parameters for SUBJECT DEVICE according to the FDA Guidance Document "Submission of Premarket Notifications for Magnetic Resonance Diagnostic Devices, issued on Nov. 18, 2016" are equivalent or better than for the PREDICATE DEVICE.
Nonclinical Tests
Nonclinical tests were performed on a phantom to evaluate the SUBJECT DEVICE with regard to the applicable imaging parameters Signal to Noise Ratio (SNR) and Image Uniformity. Tests were conducted following NEMA Standards. Moreover and following the principle of reciprocity the transmit efficiency (which is applicable to transmit / receive coils) was compared between SUBJECT DEVICE and PREDICATE DEVICE. Test results show an equivalent or better SNR and Image Uniformity performance of the SUBJECT DEVICE.
ESD-Tests have been performed and successfully passed according to the requirements of IEC 60601-2-33 Ed. 3.2 b:2015, Chapter 202.8.101.
The SUBJECT DEVICE is conforming to:
- Recognition number 19-4: AAMI / ANSI ES60601-1:2005/(R)2012 and . A1:2012, c1:2009/(r)2012 and a2:2010/(r)2012 (consolidated text) medical electrical equipment - part 1: general requirements for safety and essential performance (IEC 60601-1:2005, mod). (General II (ES/EMC)).

- Recognition Number 12-187: NEMA MS 3-2008 (R2020) Determination of ● Image Uniformity in Diagnostic Magnetic Resonance Images
All relevant safety tests were performed on the workbench and, where applicable and necessary, on Siemens, Philips and GE 3.0T MR systems.
Clinical Images
Clinical images were acquired in order to check image quality in vivo. Gradient and spin echo sequences which are typical for diagnosis were applied with standard scan parameters and image orientations (axial, sagittal and coronal). These tests show that the SUBJECT DEVICE provides adequate image quality (SNR, penetration depth, contrast, resolution and robustness against artifacts) as well as scan time and that patient comfort are good.
Conclusion as to Substantial Equivalence
Testing was performed to support this claim of substantial equivalence and to show that the modifications do not raise any new questions pertaining to safety and effectiveness.
The modifications did not affect the Indications for Use, the Intended Use and did not alter the Fundamental Scientific Technology.
RAPID Biomedical therefore believes the SUBJECT DEVICE and the PREDICATE DEVICE to be Substantially Equivalent (SE).
