The Toshiba 3T 32CH Head SPEEDER Coil is intended for use with the Toshiba Vantage Titan 3T MRI system to produce diagnostic images of the head that can be interpreted by a trained physician.
The Toshiba 3T 32CH Head SPEEDER Coil is designed for use with a Vantage Titan 3T System, manufactured by Toshiba Medical Systems Corporation.
Here's an analysis of the provided 510(k) summary regarding the Toshiba 3T 32CH Head SPEEDER Coil:
This 510(k) submission (K122638) is for a magnetic resonance imaging (MRI) coil, not an AI/algorithm-based device. Therefore, many of the typical acceptance criteria and study methodologies applicable to AI devices (e.g., human-in-the-loop, standalone performance, training set details, expert consensus for ground truth on clinical images) are not relevant here.
The device is a hardware component (an MRI coil) that works with an existing MRI system. Its performance is primarily assessed through technical specifications and physical safety, not diagnostic accuracy in the way an AI algorithm would be.
Acceptance Criteria and Reported Device Performance
| Acceptance Criteria Category | Specific Criteria/Test | Reported Device Performance/Method |
|---|---|---|
| Safety | Compliance with general medical electrical equipment standards | Tested to and found compliant with IEC 60601-1 (second and third editions) - "Medical electrical equipment - Part 1: General requirements for basic safety and essential performance". |
| Image Quality | Signal-to-Noise Ratio (SNR) | SNR was measured according to NEMA MS 9-2008, "Characterization of Phased Array Coils for Diagnostic Resonance Images." |
| Image Quality | Image Uniformity | Assessed in accordance with NEMA MS-3 2008, "Determination of Image Uniformity in Diagnostic Magnetic Resonance Images." |
| Substantial Equivalence | Comparison to predicate device | The device was deemed substantially equivalent to the 1.5T Atlas SPEEDER Head-Neck Coil (K083160) because it's also a phased-array, receive-only coil with similar functionality, despite differences in channel count, anterior attachments, and compatible MR system field strength (3T vs. 1.5T). |
Study Details (as applicable to an MRI Coil)
-
Sample size used for the test set and the data provenance:
- The document implies that the "test set" for the coil's performance was physical testing and measurements according to NEMA and IEC standards, rather than a clinical dataset of patient images.
- The sample size for these technical tests is not specified in terms of "cases" or "patients" but would refer to the number of measurements taken or the number of coils tested.
- Data provenance isn't applicable in the clinical sense (e.g., country of origin of patient data, retrospective/prospective) as these are engineering and performance tests on the device itself.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This is not applicable. Ground truth in this context refers to established engineering standards (IEC, NEMA) and physical measurements, rather than expert interpretation of clinical images. The "experts" would be the engineers and technicians performing the tests according to the specified standards.
-
Adjudication method for the test set:
- Not applicable for the type of testing performed (physical and engineering standards compliance).
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No. This is an MRI coil, not an AI algorithm. MRMC studies are designed for assessing the diagnostic performance of AI or new imaging techniques involving human interpretation.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an AI algorithm; it is a hardware component.
-
The type of ground truth used:
- For safety: Compliance with the established safety standards (IEC 60601-1).
- For image quality (SNR, Uniformity): Measurements against specified limits and methodologies defined by NEMA standards (NEMA MS 9-2008, NEMA MS-3 2008). This is an objective technical measurement, not a clinical "ground truth" like pathology or outcomes.
-
The sample size for the training set:
- Not applicable. This device does not use an AI algorithm and therefore does not have a "training set."
-
How the ground truth for the training set was established:
- Not applicable, as there is no training set for this hardware device.
Summary for K122638:
This 510(k) submission is for an MRI receive coil. The "acceptance criteria" revolve around the safety and technical performance of the hardware device itself, as evaluated against established international and national engineering standards (IEC, NEMA), rather than clinical diagnostic accuracy or AI performance. The study is a non-clinical technical evaluation demonstrating compliance with these standards and substantial equivalence to a predicate device. The document does not involve AI, clinical image interpretation studies, or patient data in the context of performance testing.

510(k) SUMMARY OF SAFETY AND EFFECTIVENESS
Comparison with Predicate Devices 10.
| 510(k) # | Legally marketed predicate device | Manufacturer |
|---|---|---|
| K083160 | 1.5T Atlas SPEEDER Head-Neck Coil | Quality Electrodynamics |
The Toshiba 3T 32CH Head SPEEDER Coil in this submission and the 1.5T Atlas SPEEDER Head-Neck Coil described in K083160 are both phased-array, receive-only coils. The main differences are that the Toshiba 3T 32CH Head SPEEDER Coil has a higher channel count (32 vs. 15), fewer anterior attachments (2 vs. 4) and is designed for use with a 3T system as opposed to a 1.5T system compared to the predicate coil.
Non-Clinical Tests 11.
The Toshiba 3T 32CH Head SPEEDER Coil was tested to and found to be compliant with IEC 60601-1, Medical electrical equipment - Part 1: General requirements for basic safety and essential performance, second and third editions.
The signal-to-noise ratio (SNR) was measured according to NEMA MS 9-2008, Characterization of Phased Array Coils for Diagnostic Resonance Images.
Image Uniformity was assessed in accordance with NEMA MS-3 2008, Determination of Image Uniformity in Diagnostic Magnetic Resonance Images.
Conclusion 12.
It is the opinion of Quality Electrodynamics that the Toshiba 3T 32CH Head SPEEDER Coil is substantially equivalent to the above-listed legally marketed predicate devices. Use of the Quality Electrodynamics coil does not result in any new potential hazards.

Dear Ms. Aras:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of
