Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are not explicitly stated in a quantifiable manner (e.g., "accuracy must be >90%"). Instead, the primary acceptance criterion for the clinical testing appears to be agreement among radiologists that the mobile devices running ResolutionMD Mobile provide image quality and diagnostic confidence equivalent or comparable to a predicate PACS workstation for clinical use across various modalities, leading to the same diagnosis.
| Criteria Category | Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|---|
| Clinical Performance | Image quality and diagnostic confidence on mobile devices with ResolutionMD Mobile must be equivalent or comparable to a predicate PACS workstation for diagnostic radiology across X-ray, ultrasound, PET, and SPECT modalities. Radiologists must be comfortable with diagnoses made on the mobile devices. The overall clinical image display quality on mobile devices must be equivalent to the PACS workstation for identification of clinically-relevant pathology. Radiologists must indicate acceptable quality for regular use and comfort reviewing images on the devices. The same diagnosis should be made on mobile devices with ResolutionMD as on the predicate PACS workstation in both office and low light conditions. | All nine radiologists agreed that the iOS and Android mobile devices (smartphones and tablets) were either "equivalent" or "comparable" to the predicate PACS workstation across all four modalities (X-ray, ultrasound, PET, SPECT) and of adequate quality for clinical use. They were comfortable with the diagnoses made on the mobile devices using the ResolutionMD Mobile software. All agreed that the overall clinical image display quality on the iOS and Android devices was equivalent to the PACS workstation for the identification of clinically-relevant pathology. All nine radiologists indicated that the software and devices provide acceptable quality for regular use and they were comfortable reviewing images on the devices. For all individual cases, there was agreement by all reviewers that the same diagnosis would be made on the mobile devices with ResolutionMD as on the predicate PACS workstation in office lighting conditions and in low light conditions. None noted perception differences between lighting conditions. |
| Technical Performance | Mobile device performance (iOS/Android, smartphones/tablets) in combination with ResolutionMD Mobile must provide acceptable image quality for diagnostic radiology, particularly concerning luminance response as per AAPM guidelines. | Specific results regarding measured luminance from mobile devices with respect to target luminance response using JND plots were provided to the FDA as requested. (The specific numerical values or pass/fail thresholds are not detailed in the summary, but the implication is they met an acceptable standard.) |
| Software Verification/Validation | The software must undergo functional, smoke, and regression tests, and beta tests with minimal critical defects. Clinical workflows must be validated for usability and consistency across client platforms (Web, iOS, Android). | Verification testing included over 160 separate tests, executed multiple times by different testers (functional, smoke, regression). Beta tests were performed. Most tests passed. Defects were either fixed or logged as unresolved anomalies with impact on safety/effectiveness annotated. Validation testing was performed by trained radiology personnel based on typical clinical workflows, including usability assessment and consistency across Web, iOS, and Android platforms. |
2. Sample size used for the test set and the data provenance
- Sample Size for Test Set: The document mentions "a series of typical yet challenging X-ray, ultrasound, PET and SPECT cases." The exact number of cases is not specified, only that there were "individual cases" for which agreement was reached.
- Data Provenance: The document does not explicitly state the country of origin or whether the data was retrospective or prospective. It just refers to "typical yet challenging X-ray, ultrasound, PET and SPECT cases."
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Nine (9) board-certified radiologists.
- Qualifications of Experts: Board-certified radiologists in the United States. No further detail on experience (e.g., "10 years of experience") is provided, but board-certification implies a certain level of expertise.
4. Adjudication method for the test set
The adjudication method appears to be a form of consensus or agreement. The study states, "All nine radiologists agreed that the iOS and Android mobile devices... were either 'equivalent' or 'comparable'..." and "For all the individual cases, there was agreement by all reviewers that the same diagnosis would be made..." This suggests a process where all radiologists had to concur, but the specific mechanics (e.g., independent review followed by discussion, or a sequential review) are not detailed. It is not explicitly a 2+1 or 3+1 method where disagreements are resolved by an additional reader.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Comparative Effectiveness Study: Yes, a comparative assessment was done. The study specifically compared diagnostic confidence on mobile devices with ResolutionMD Mobile to a predicate PACS workstation. This constitutes a comparison of human readers using different display/interpretation systems.
- Effect Size of Human Readers Improvement with AI vs. without AI Assistance: This device is a PACS (Picture Archiving and Communication System) viewer for mobile devices, not an AI-powered diagnostic assist tool. Therefore, the study does not evaluate improvement with AI assistance. It evaluates the equivalence of a mobile viewing platform to a full workstation. The "effect size" is expressed qualitatively as being "equivalent" or "comparable" to the predicate PACS workstation.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
No, a standalone (algorithm only) performance study was not done for diagnostic interpretation. ResolutionMD Mobile is a display and communication system, intended for use by trained professionals, not to autonomously interpret images. The clinical testing specifically involved human radiologists making diagnoses using the device.
7. The type of ground truth used
The ground truth was established by expert consensus among the panel of nine board-certified radiologists. They made comparative assessments and agreed on the diagnostic equivalence between the mobile device and the predicate PACS workstation for the tested cases. There is no mention of pathology or outcomes data being used as the definitive ground truth reference.
8. The sample size for the training set
The document does not provide information on a "training set" for the ResolutionMD Mobile software in the context of diagnostic interpretation. As a PACS viewer, it's not a machine learning model that is "trained" on images in the same way an AI algorithm for disease detection would be. The software is developed and verified through standard software engineering practices.
9. How the ground truth for the training set was established
Not applicable, as there is no mention of a training set for the diagnostic function of the device in the context of machine learning. The "ground truth" for the software's functionality would be adherence to DICOM standards, performance metrics (like luminance), and usability, as confirmed by verification and validation testing, rather than medical ground truth established from labeled medical images for training purposes.

Technological Characteristics
The ResolutionMD™ Mobile software has the same technological characteristics as the predicate ResolutionMD Devices and has the same uses and applications as the predicate devices. Both the device and predicates are used by the clinician as a diagnostic, review, and analysis tool for radiological images.
Software Verification and Validation Testing
Verification testing consisting of more 160 separate tests, each executed multiple times by different testers, was performed for this device. Testing included functional, smoke and regression tests and was complemented by beta tests performed by Calgary Scientific's OEM distribution partners. The vast majority of tests passed our testing criteria. Any defects found or reported were either fixed or logged in the Unresolved Anomalies report included with this submission and annotated as to any impact on safety or effectiveness including applicable workarounds.
{2}------------------------------------------------
Validation testing based on typical clinical workflows was performed by trained radiology personnel. Validation includes usability assessment and consistency across three client platforms; Web, iOS and Android.
Performance Testing
Performance testing was conducted to qualify iOS and Android mobile devices, both smartphones and tablets, as devices whose off-the-shelf performance in combination with the overall attributes of the ResolutionMD Mobile solution provides acceptable image quality for diagnostic radiology.
The tests were performed in accordance with the description and requirements described in the AAPM Assessment of Display Performance for Medical Imaging Devices (2005) document by an ISO 17025-certified third party to ensure high quality laboratory results. The test equipment and calibration was certified traceable to NIST.
The specific results regarding the measured luminance from the mobile devices with respect to the target luminance response using JND plots was provided to the FDA as requested.
Clinical Testing
Clinical testing was conducted by a panel of nine board-certified radiologists in the United States. The radiologists conducted a side-by-side comparative assessment of the iOS and Android mobile devices running ResolutionMD Mobile with the predicate PACS workstation. A series of typical yet challenging X-ray, ultrasound, PET and SPECT cases were reviewed on each device. Comparative assessments of image quality and diagnostic confidence were made by each radiologist.
All nine radiologists agreed that the iOS and Android mobile devices, both smartphones and tablets, were either "equivalent" or "comparable" to the predicate PACS workstation across all four modalities and of adequate quality for clinical use. They were comfortable with the diagnoses made on the mobile devices using the ResolutionMD Mobile software. All agreed that the overall clinical image display quality on the iOS and Android devices was equivalent to the PACS workstation for the identification of clinically-relevant pathology.
All nine radiologists indicated that the software and devices provide acceptable quality for regular use and they were comfortable reviewing images on the devices.
For all the individual cases, there was agreement by all reviewers that the same diagnosis would be made on the mobile devices with ResolutionMD as on the predicate PACS workstation in office lighting conditions and in the low light conditions. None of the reviewers noted any differences in their perception of the images between the low light and office lighting conditions.
