The provided text describes information about the submission of the MAGNETOM Free.Max and MAGNETOM Free.Star MRI systems for FDA 510(k) clearance, and references a specific AI feature called "Deep Resolve Boost." However, it does not contain acceptance criteria or a detailed study proving the device meets specific performance criteria for the AI feature.
The section titled "Test statistics and test results" for Deep Resolve Boost (Table 1, page 7) mentions that the impact of the network was characterized by quality metrics such as PSNR and SSIM, and visual inspection. It also states: "After successful passing of the quality metrics tests, work-in-progress packages of the network were delivered and evaluated in clinical settings with cooperation partners." This suggests internal testing and evaluation, but does not provide the specific numerical acceptance criteria or the detailed results of these tests.
Therefore, I cannot fully complete the requested table and answer all questions due to the lack of this specific information in the provided document.
However, I can extract the available information regarding the AI feature "Deep Resolve Boost" as much as possible:
1. Table of acceptance criteria and the reported device performance:
| Metric / Criteria | Acceptance Criteria (Stated or Implied) | Reported Device Performance (Specifics not provided in document) |
|---|---|---|
| Deep Resolve Boost | ||
| Peak Signal-to-Noise Ratio (PSNR) | Must pass initial quality metrics tests. | Quantified, but specific numerical values are not reported. |
| Structural Similarity Index (SSIM) | Must pass initial quality metrics tests. | Quantified, but specific numerical values are not reported. |
| Visual Inspection for Artifacts | Must ensure potential artifacts are detected that are not well captured by PSNR/SSIM. | Images visually inspected. |
| Clinical Evaluation | Must be evaluated in clinical settings with cooperation partners. | "work-in-progress packages of the network were delivered and evaluated in clinical settings with cooperation partners." (No specific results or findings reported in this document.) |
2. Sample size used for the test set and the data provenance:
- Test Set (Validation set for AI feature Deep Resolve Boost):
- Sample Size: 1,874 2D slices.
- Data Provenance: "in-house measurements and collaboration partners." The document does not specify the country of origin.
- Retrospective or Prospective: Retrospectively created from ground truth by data manipulation and augmentation.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Number of experts: Not specified.
- Qualifications of experts: The document states the "acquired datasets represent the ground truth for the training and validation," but it does not specify how this ground truth was established in terms of expert involvement for the test set. It mentions "clinical settings with cooperation partners" for evaluation, but this is distinct from ground truth establishment.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not specified. The document states "acquired datasets represent the ground truth," suggesting pre-existing data or a different method of ground truth establishment than explicit reader adjudication for this AI feature.
5. 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:
- The document states "No clinical tests were conducted to support substantial equivalence for the subject device" (page 10). It mentions that "work-in-progress packages of the network were delivered and evaluated in clinical settings with cooperation partners," but this is not described as an MRMC comparative effectiveness study, nor are any results on human reader improvement reported.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- The performance of the "Deep Resolve Boost" AI feature was characterized by "quality metrics such as peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM)" and visual inspection, which suggests a standalone evaluation of the algorithm's output against a reference standard. Specific results are not provided.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For Deep Resolve Boost: "The acquired datasets represent the ground truth for the training and validation." Input data for training was "retrospectively created from the ground truth by data manipulation and augmentation." This implies that high-quality, likely clinical-grade, MRI scans acquired without the AI feature were considered the "ground truth" to which the AI-processed images were compared. It's not explicitly stated if this "ground truth" itself was established by expert consensus, but it infers it from high-quality clinical acquisition.
8. The sample size for the training set:
- For Deep Resolve Boost: 24,599 2D slices.
9. How the ground truth for the training set was established:
- "The acquired datasets represent the ground truth for the training and validation. Input data was retrospectively created from the ground truth by data manipulation and augmentation. This process includes further under-sampling of the data by discarding k-space lines, lowering of the SNR level by addition of noise and mirroring of k-space data."
- This indicates that "ground truth" was established by using full, high-quality MR images. The "input data" for the AI model (which the AI then "boosts") was intentionally degraded (under-sampled, noised) from this high-quality ground truth. The AI's task is to reconstruct the degraded input data back to resemble the original high-quality "ground truth."

5. Indications for Use
MAGNETOM Free.Max:
The indications for use for the subject device MAGNETOM Free.Max with syngo MR XA60A is extended to include MR imaging during interventional procedures compared to the predicate device MAGNETOM Free.Max with syngo MR XA50A:
MAGNETOM Free.Max system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal, and oblique cross-sectional images that display the internal structure and/or function of the head. body, or extremities. Other physical parameters derived from the images may also be produced. Depending on the region of interest, contrast agents may be used. These images and the physical parameters derived from the images when interpreted by a trained physician vield information that may assist in diagnosis.
MAGNETOM Free.Max may also be used for imaging during interventional procedures when performed with MR-compatible devices such as MR Safe biopsy needles.
MAGNETOM Free.Star:
The indications for use for the subject device MAGNETOM Free.Star with syngo MR XA60A is the same as the predicate device MAGNETOM Free.Star with syngo MR XA50A:
MAGNETOM Free.Star system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal, and oblique cross-sectional images that display the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images may also be produced. Depending on the region of interest, contrast agents may be used. These images and the physical parameters derived from the images when interpreted by a trained physician vield information that may assist in diagnosis.
Indications for use modification rationale for MAGNETOM Free.Max:
The product features that support MR imaging during interventional procedures are released in subject device MAGNETOM Free.Max with syngo MR XA60A.
MR imaging during interventional procedures is already included in the reference device MAGNETOM Sola's indications for use and is 510(k) cleared (K221733, cleared on September 13, 2022).
This difference in indications for use does not alter the functionality in assisting diagnosis of the subject device as a magnetic resonance diagnostic device.
Therefore, this difference does not constitute a new intended use according to FDA Guidance "The 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)]".

| Deep Resolve Boost | |
|---|---|
| Sample size | 26,473 2D slices |
| Note: due to reasons of data privacy, we did not record how manyindividuals the datasets belong to. Gender, age and ethnicity distributionwas also not recorded during data collection. Due to the networkarchitecture, attributes like gender, age and ethnicity are not relevant tothe training data. | |
| Sample source | in-house measurements and collaboration partners |
| Dataset slipt | Training: 24,599 slices |
| Validation: 1,874 slices | |
| Note: Data split maintained similar data distribution (e.g. contrast,orientation, field strength, ...) in both training and validation datasets. | |
| Equipments | 1.5T and 3T MRI scanners [1] |
| Protocols | Representative protocols (T1, T2 and PD with and withoutfat saturation) which have been altered (e.g. to increaseSNR, increase resolution or reduced acceleration). |
| Body regions | a broad range of different body regions |
| Clinicalsubgroups | No clinical subgroups have been defined for the datasets. |
| Counfouders | The input and output variables of the network have beenderived from the same dataset so that no confounders existfor the training methodology. |
| Test statisticsand testresults | The impact of the network has been characterized by severalquality metrics such as peak signal-to-noise ratio (PSNR) andstructural similarity index (SSIM). Additionally, images wereinspected visually to ensure that potential artefacts are detectedthat are not well captured by the metrics listed above.After successful passing of the quality metrics tests, work-in-progress packages of the network were delivered and evaluated inclinical settings with cooperation partners. |
| Referencestandard | The acquired datasets represent the ground truth for the trainingand validation. Input data was retrospectively created from theground truth by data manipulation and augmentation. This processincludes further under-sampling of the data by discarding k-spacelines, lowering of the SNR level by addition of noise and mirroringof k-space data. |

12.Conclusion as to Substantial Equivalence
MAGNETOM Free.Max and MAGNETOM Free.Star with software syngo MR XA60A have the same basic technological characteristics as the predicate device systems, MAGNETOM Free.Max and MAGNETOM Free.Star with syngo MR XA50A (Cleared with K220575 on June 24, 2022), with respect to the magnetic resonance features and functionalities. While there are some differences in technical features compared to the predicate devices, the differences have been tested and the conclusions from
{12}------------------------------------------------
all verification and validation data suggest that the features bear an equivalent safety and performance profile to that of the predicate devices and reference devices.
Siemens believes that MAGNETOM Free.Max and MAGNETOM Free.Star with software syngo MR XA60A are substantially equivalent to the currently marketed device MAGNETOM Free.Max and MAGNETOM Free.Star with syngo MR XA50A.
§ 892.1000 Magnetic resonance diagnostic device.
(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.
