The description focuses on geometric alignment and calculating motion data from 3D surfaces using a structured light technique. There is no mention of AI/ML algorithms, training data, or performance metrics typically associated with AI/ML.
No
The device tracks patient movement during an MRI session to support or augment the MRI scanner's performance, it does not directly treat or diagnose any medical condition.
No
The device tracks patient movement during an MRI session and provides real-time position data to the scanner. Its purpose is to support and augment the performance of MRI scanners, not to diagnose medical conditions or identify the presence/absence of a disease.
No
The device description explicitly states it uses a camera and an infrared light modulator to reconstruct 3D surfaces, indicating the presence of hardware components beyond just software.
Based on the provided information, the TCL3 Motion Tracking System is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The TCL3 system directly interacts with the patient's head and uses a structured light technique to track its movement. It does not analyze biological samples like blood, urine, or tissue.
- The intended use is to track patient movement during an MRI session. This is a function related to imaging and patient positioning, not the diagnosis of a disease or condition through the analysis of biological specimens.
- The device description focuses on capturing 3D surface data of the patient's head. This is a physical measurement, not a chemical, biological, or immunological analysis of a specimen.
The TCL3 Motion Tracking System is an accessory to an MRI scanner that aids in image acquisition by compensating for patient motion. This falls under the category of medical devices used for imaging and patient management, not in vitro diagnostics.

Intended Use / Indications for Use
The TCL3 Motion Tracking System is an accessory to a Magnetic Resonance Imaging (MRI) scanner. The system uses a markerless sensor based technology for tracking of patient movement during an MRI session. It provides the current position of the patient in real-time to the MRI scanner. The TCL3 System is intended to support, supplement and/or augment the performance of the Siemens Magnetom Skyra, Siemens Magnetom Prisma, Philips Achieva and GE Signa Premier scanners.

Device Description
The TCL3 Motion Tracking System monitors the patient's head for the scan. It can be turned off between patient scans. While running, the TCL3 Motion Tracking System continuously scans the surface of the patient's head, producing high-resolution 3D surfaces consisting of thousands of individual points. A structured light technique is utilized, using the combination of a camera and an infrared light modulator to reconstruct 3D surfaces of the patient's head. Each second, 30 surfaces are created. Each of these surfaces is used for geometric alignment relative to an initial reference position obtained at the beginning of the scan. From these alignments, motion data can be calculated in real-time.

E. Performance Data
Each specification of the TCL3 Motion Tracking System has been verified and validated as required by the risk analysis. All design verification and validation activities were performed by the designated individual(s) and the results demonstrated that the predetermined acceptance criteria were met.
| ISO 14971 | Application of risk management to medical devices |
|---|---|
| IEC 60601-1 | Medical electrical equipment- General requirements for basic safety and |
| essential performance | |
| IEC 60601-1-2 | Electromagnetic disturbances |
| IEC 62304 | Medical device software - Software life-cycle processes |
The verification and validation testing included testing to the following applicable standards:
Verification and validation testing were completed in accordance with the company's Design Control process in compliance with 21 CFR Part 820.30. Successful results for the following tests were included in the submission as performance data supporting substantial equivalence:
-
- Bench testing for electrical and mechanical safety in compliance with the standards cited above
- Bench testing for EMC in compliance with the standard cited above 2.

- Software testing, consisted of verification and validation testing in compliance with ISO 62304, including test cases related to off the shelf software, as well as cybersecurity features and wireless coexistence.
-
- Bench testing for tracking quality and accuracy, MR compatibility and Mechanical compatibility
Clinical data was not required for this type of device.
F. Conclusion
Potential risks were identified according to the ISO 14971 Standards. The risks were analyzed with regard to risk/benefit category and mitigations were implemented and tested as part of the performance testing described above. All risk mitigations were satisfactorily verified and validated. Where there were technological differences from the predicate, the performance data demonstrated that these did result in any new issues of safety or efficacy.
Therefore, the TCL3 Motion Tracking System is substantially equivalent to the predicate device with regards to intended use and technological characteristics. Results of performance testing demonstrated that the device met the design requirements and as well as the user needs.
