The summary describes standard image processing and analysis techniques for dynamic MRI data, without mentioning AI or ML.
No.
The document states that Dynamika Version 5.0 is an image processing software package used for viewing, processing, and analysis of medical images, and for visualization, analysis, and reporting of dynamic MRI data. It does not mention any therapeutic function or direct intervention to treat a disease or condition.
Yes
Explanation: The software provides tools for visualization, analysis, and reporting of dynamic MRI data, including calculating permeability parameters and generating parametric maps to be interpreted by trained physicians. This information is intended to yield clinically useful information, which is a hallmark of diagnostic devices.
Yes
The device is explicitly described as a "software package" that runs on standard off-the-shelf workstations and processes images from existing DICOM-compliant imaging devices. There is no mention of proprietary hardware included with the device.
Based on the provided information, Dynamika Version 5.0 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Dynamika's Function: Dynamika Version 5.0 processes and analyzes medical images acquired directly from the patient using MRI and other imaging modalities. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it's for "image viewing, processing and analysis of medical images" and "visualization, analysis and reporting of dynamic MRI data." This is focused on interpreting images of the body, not analyzing samples from the body.
Therefore, Dynamika Version 5.0 falls under the category of medical imaging software, not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Laboratory or Non-clinical testing: Image Analysis Limited has conducted extensive verification and validation testing of the Dynamika Version 5.0 system, as a PACS that has the capability to provide reliable postprocessing and display of dynamic MRI images for multi-parametric analysis. All of the different components have been stress tested to ensure that the system as a whole provides the capabilities to operate safely and effectively according to its intended use. The tests performed included: Product Risk Assessment, Software verification and validation testing (including algorithm (unit) level testing, integration and system functional testing). The Dynamika Version 5.0 system also complies with the requirements of the FDA recommended voluntary NEMA DICOM safety standard for PACS.
Clinical testing: No clinical testing was used to demonstrate substantial equivalence between Dynamika Version 5.0 and the predicate device (Olea Sphere Version 2.3) as these types of devices have been on the market for many years with proven safety and efficacy of use. Therefore, the non-clinical testing detailed within the submission supports the substantial equivalence of this device.

VIII. Laboratory or Non-clinical testing.
Image Analysis Limited has conducted extensive verification and validation testing of the Dynamika Version 5.0 system, as a PACS that has the capability to provide reliable postprocessing and display of dynamic MRI images for multi-parametric analysis. All of the different components have been stress tested to ensure that the system as a whole provides the capabilities to operate safely and effectively according to its intended use.
The tests performed included:
- Product Risk Assessment.
- Software verification and validation testing. This includes algorithm (unit) level testing, integration and system functional testing.
This is identical to the predicate device.
The Dynamika Version 5.0 system also complies with the requirements of the FDA recommended voluntary NEMA DICOM safety standard for PACS, which is identical to the predicate device.
IX. Clinical testing.
No clinical testing was used to demonstrate substantial equivalence between Dynamika Version 5.0 and the predicate device (Olea Sphere Version 2.3) as these types of devices have been on the market for many years with proven safety and efficacy of use. Therefore, the non-clinical testing detailed within the submission supports the substantial equivalence of this device.
X. Conclusions.
Based upon the comparison of the intended use and technological characteristics with those of the predicate device, the Dynamika Version 5.0 software system has the same general intended use (with differences in indications for use due to additional modules available for use with the predicate device) and similar technological characteristics. The differences in indications for use do not result in a new intended use or raise any additional safety and effectiveness concerns. Non-clinical performance and validation testing at algorithm, integration and system level demonstrates that this device does not raise any new safety and effectiveness concerns. Therefore, Dynamika Version 5.0 is substantially equivalent to the predicate device, Olea Sphere Version 2.3 system manufactured by Olea Medical (K132095).
