No
The summary describes receive-only coils for an MRI system and mentions standard image processing techniques, but there is no mention of AI, ML, or related concepts like training or test sets for algorithms.
No
The device is described as an "imaging device" used to produce images and provide information useful in "diagnosis determination," not for treating a disease or condition.
Yes
The device is described as an "imaging device" that provides information useful in "diagnosis determination" when interpreted by a trained physician, and its coils are used for "obtaining diagnostic images."
No
The device description explicitly states that the devices are "recieve-only multiple array devices" and "coils," which are hardware components used in MRI systems. The summary also mentions "image processing techniques," but the core device being described is a physical coil.
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 description clearly states that this is an imaging device (an MR system and its associated coils) that obtains physiological and clinical information non-invasively. It produces images of internal structures based on magnetic resonance signals.
- Intended Use: The intended use is to provide images that, when interpreted by a trained physician, can be useful in diagnosis determination. This is a characteristic of medical imaging devices, not IVDs.
- No Sample Analysis: There is no mention of analyzing samples taken from the body. The device directly interacts with the patient's body to generate images.
Therefore, the device described is a medical imaging device, specifically an MRI system and its coils, and does not fit the definition of an In Vitro Diagnostic.

Device Description
The MR-IBC-120, OASIS RAPID Breast Coil is a recieve-only multiple array device used for obtaining diagnostic images of the breast with the OASIS MRI System. The MR-NVC-120, OASIS NV Coil is a recieve-only multiple array device used for obtaining diagnostic images of the head and neck with the OASIS MRI System.
Magnetic Resonance Imaging (MRI) is based on the fact that certain atomic nuclei have electromagnetic properties that cause them to act as small spinning bar magnets. The most ubiquitous of these nuclei is hydrogen, which makes it the primary nuclei currently used in magnetic resonance imaging. When placed in a static magnetic field, these nuclei assume a net orientation or alignment with the magnetic field, referred to as a net magnetization vector. The introduction of a short burst of radiofrequency (RF) excitation of a wavelength specific to the maqnetic field strength and to the atomic nuclei under consideration can cause a re-orientation of the net magnetization vector. When the RF excitation is removed, the protons relax and return to their original vector. The rate of relaxation is exponential and varies with the character of the proton and its adjacent molecular environment. This re-orientation process is characterized by two exponential relaxation times, called T1 and T2.
A RF emission or echo that can be measured accompanies these relaxation events. The emissions are used to develop a representation of the relaxation events in a three dimensional matrix. Spatial localization is encoded into the echoes by varying the RF excitation, applying appropriate magnetic field gradients in the x, y, and z directions, and changing the direction and strength of these gradients. Images depicting the spatial distribution of the NMR characteristics can be reconstructed by using image processing techniques similar to those used in computed tomography.
The MR-IBC-120. OASIS RAPID Breast Coil is a recieve-only device suitable for imaging the breast. The coil consists of 8 elements. The signal output of each element is independently processed by the MRI system to enhance performance.
The MR-NVC-120, OASIS NV Coil recieve-only suitable for imaging human foot region, muscle, born structure, cartilage, etc. The coil consists of 8 elements. The signal output of each element is independently processed by the MRI system to enhance performance.

(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
