READY View is an image analysis software that allows the user to process dynamic or functional volumetric data and to generate maps that display changes in image intensity over time, echo time, b-value (Diffusion imaging) and frequency (Spectroscopy). The combination of acquired images, reconstructed images, calculated parametric images, tissue segmentation, annotations and measurement performed by the clinician allows multiparametric analysis and may provide clinically relevant information for diagnosis.
READY VIEW (K110573) is a suite of applications developed to improve multi-parametric exams by enobling the analysis of MR generated data sets containing multiple images for each scan location. The MR data sets may be any of the following:
- A time series
- A diffusion weighted scan
- A diffusion tensor scan
- A variable echo imaging
- A blood oxygen level dependent imaging
- Spectroscopy (Single voxel and 2D or 3D CSI)
The READY View platform provides a combination of protocols, applications and tools that enables a fast, easy and quantified analysis of the multiple data sets.
Brain View is a post processing image analysis software package that provides advanced techniques to aid in the diagnosis of neurological and oncological diseases. Brain View is an option with the READY View platform and offers two advanced protocols: - FiberTrak
- Arterial Spin Labeling (ASL)
READY View along with Brain View option are available on the Advantage Workstation (AW), Advantage Workstation Server Gen 2 and AW Server PACS, for viewing and processing Magnetic Resonance images.
The basis for this submission is a modification of a legally marketed device to incorporate additional features. The following additional functional protocols can now be post processed using READY View software:
Brain View which is a post processing image analysis software package that provides advanced techniques to aid in the diagnosis of neurological and oncological diseases now offers two additional advanced protocols : - BrainStat
- BrainStat AIF
Body View is a post processing image analysis software package that provides advanced techniques to aid in the diagnosis of oncological diseases in the human body. Body View is an option : with the READY View platform and offers two advanced protocols: - Signal Enhancement Ratio (SER)
- MR Standard
READY View along with Brain View and Body View options are available on the Advantage Workstation (AW), Advantage Workstation Server Gen 2 and AW Server PACS, for viewing and processing Magnetic Resonance images.
The provided 510(k) submission for GE Healthcare's READY View states that no clinical studies were required to support substantial equivalence for this device. Therefore, there is no information available in this document regarding acceptance criteria, device performance, sample sizes, expert involvement, or ground truth establishment based on clinical data.
The submission focuses entirely on non-clinical tests to demonstrate substantial equivalence to its predicate device (READY View K110573).
Here's a breakdown of what the document does state regarding testing:
1. A table of acceptance criteria and the reported device performance
- Not Applicable. The document explicitly states: "The subject of this premarket submission, READY View, did not require clinical studies to support substantial equivalence." Therefore, no clinical performance metrics or acceptance criteria based on patient outcomes are provided.
- The "Summary of Non-Clinical Tests" lists general quality assurance measures:
- Risk Analysis
- Requirements Reviews
- Design Reviews
- Performance testing (Verification)
- Safety testing (Verification)
- Simulated use testing (Validation)
However, specific acceptance criteria or detailed results from these non-clinical tests are not disclosed in this summary.
2. Sample sized used for the test set and the data provenance
- Not Applicable. No clinical test set. The document states: "All clinical images required for verification and validation activities were obtained from legally marketed GE MR Systems." This indicates that existing images were used for internal testing and validation, but not for a formal clinical study to prove substantial equivalence of the new features. The number of such images is not specified, nor is their provenance (e.g., country of origin, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not Applicable. No clinical test set requiring expert ground truth in the context of this submission.
4. Adjudication method for the test set
- Not Applicable. No clinical test set.
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
- Not Applicable. No MRMC study was conducted or reported. The device is described as "post processing image analysis software" that "allows multi-parametric analysis and may provide clinically relevant information for diagnosis." There is no mention of AI assistance for human readers or comparative effectiveness in this context.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. While the device is "algorithm only" in its function as image analysis software, the submission does not present a standalone performance study in the typical sense of measuring diagnostic accuracy against a ground truth. Its equivalence is based on non-clinical testing and comparison to its predicate device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Not Applicable. For non-clinical verification and validation activities utilizing "clinical images," the type of ground truth used to assess the software's processing capabilities (e.g., whether it correctly generates maps or graphs based on its algorithms) is not specified. It's likely that the "ground truth" for these internal tests was the expected output of the algorithms given the input data, verified by engineers or subject matter experts against predefined specifications, rather than clinical ground truth (like pathology or expert consensus on diagnosis).
8. The sample size for the training set
- Not Applicable. There is no mention of machine learning or AI training sets in this submission. The device description focuses on its function as "post processing image analysis software" that applies protocols and tools for analysis, not on learning from data.
9. How the ground truth for the training set was established
- Not Applicable. As no training set is mentioned, this question is not relevant to the provided text.
In summary, the 510(k) submission for READY View (K113456) explicitly states that clinical studies were not required to demonstrate substantial equivalence for the modifications introduced (new protocols like BrainStat, BrainStat AIF, SER, MR Standard). The reliance was on non-clinical software verification and validation activities.
§ 892.2050 Medical image management and processing system.
(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)
