The provided document is a 510(k) premarket notification for a Picture Archiving and Communication System (PACS) with a medical workstation (VM PACS with VM Medical Workstation). This type of device is classified as a Class II medical device (21 CFR 892.2050) and is subject to general controls. The document aims to demonstrate substantial equivalence to a legally marketed predicate device (K123174 CENTRICITY PACS-IW WITH UNIVERSAL VIEWER by GE HEALTHCARE).
Crucially, this document is a regulatory submission for a PACS system, which is a software for storing, displaying, and managing medical images. It is not an AI/ML-driven diagnostic device that would typically have acceptance criteria based on diagnostic performance metrics like sensitivity, specificity, or AUC, nor does it involve a "study that proves the device meets the acceptance criteria" in the sense of a clinical trial demonstrating AI performance.
Instead, the "acceptance criteria" for a PACS system in a 510(k) submission generally revolve around demonstrating compliance with DICOM standards, functional equivalence to a predicate device, and verification of software functionality and safety. The "study" mentioned is not a clinical performance study but rather a demonstration of technical characteristics and functional equivalence.
Therefore, many of the requested points regarding AI/ML performance, sample sizes for test/training sets, ground truth establishment, expert adjudication, and MRMC studies are not applicable to this specific type of device and submission.
Here's how I can address the prompts based on the provided document:
Acceptance Criteria and Device Performance for VM PACS with VM Medical Workstation
Since this is a PACS system and not an AI/ML diagnostic tool, the "acceptance criteria" are derived from demonstrating substantial equivalence to a predicate device and adherence to relevant standards (primarily DICOM). The "reported device performance" refers to the system's demonstrated functionality as described in the submission.
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria (Inferred from Substantial Equivalence and DICOM Compliance) | Reported Device Performance (Summary) |
|---|---|
| DICOM Standard Compliance | VM PACS and VM Medical Workstation are designed by DICOM Standards (e.g., DICOM 3 compliance explicitly mentioned). |
| Image Storage and Retrieval | VM PACS is designed to store Medical DICOM Images and make them available for diagnostics or transfer to other DICOM devices. It can receive, send, query, and retrieve studies from other DICOM Applications. |
| Image Display and Manipulation | VM Medical Workstation provides diagnostic tools for image diagnosis (CT, MR, PT, CR, DX, NM, MG, XA, RF, SC, US, ES) including zoom, Window & Level variation and presets, measurements, and a reporting tool. VM Clinical Viewer provides web access for remote viewing. |
| Data Integrity (No Modification of Images) | VM PACS is explicitly stated not to create or modify DICOM images stored in it. |
| Compatibility with Modalities and Operating Systems | Supports all DICOM modalities, Dicom, JPEG, and JPEG 2000 compliant image sources, TCP/IP connectivity. Compatible with Microsoft Windows /XP Professional/7/8 and Windows Server 2003/2008/2012 (32/64 bits) for server and workstation. Web interface has Linux and iOS compatibility. |
| Equivalence in Intended Use and Indications | Intended use and indications for use are presented as substantially equivalent to the predicate device, focusing on receiving, storing, distributing, processing, and displaying DICOM and non-DICOM information throughout a clinical environment, and providing diagnostic tools for trained professionals. |
| Safety and Effectiveness (No New Issues) | "This device poses no new issues of safety or effectiveness, and is substantially equivalent to the predicate device." (This is a conclusion made by the applicant based on their comparison and nonclinical testing, not a specific performance metric.) "The device does not contact the patient, nor does it control any life sustaining devices." "A trained physician... interprets images and information displayed and printed by this software." |
| Software Development & Validation | Designed, developed, tested, and validated according to written procedures (though details not provided for specific "acceptance criteria" here, it's a general claim for regulatory compliance). |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document as it's not a clinical performance study involving a test set of patient data to measure diagnostic accuracy. The "testing" mentioned refers to nonclinical testing of technical characteristics, general function, and application (para 7.3.3).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not provided and is not applicable to this type of device submission. There is no "ground truth" establishment in the context of image interpretation performance for a PACS system; its primary function is image management and display.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not provided and is not applicable. Since there is no clinical test set for diagnostic performance, there's no adjudication method.
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
There was no MRMC comparative effectiveness study and this is not applicable as the device is a PACS system, not an AI-driven diagnostic aid.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. The device is a Picture Archiving and Communication System, which is a foundational system for medical imaging workflow, not a standalone diagnostic algorithm. Human users (physicians, radiologists) interact directly with the software for viewing and interpreting images.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
This is not applicable. The device's function does not involve making diagnostic claims that would require a "ground truth" for diagnostic performance evaluation.
8. The sample size for the training set
This information is not provided and is not applicable. The device is not an AI/ML model trained on a dataset for diagnostic purposes.
9. How the ground truth for the training set was established
This information is not provided and is not applicable.

BodyViz is a software device that receives digital images and data from various sources (i.e. CT scanner, MRI scanners). Data must be in DICOM format. Images and data are parsed, stored, processed, and displayed within the system as 3D representations. Image tools are available such as translation, rotation, scaling, clipping, and coloring. A data tool is available to window the displayed representation to certain tissue types based on tissue density (e.g., muscle, bone, or skin). Analysis of images and diagnosis is not performed by the software but by physicians or trained professionals.
BodyViz is a software based application for creating 3D models of patient data from 2D scan slices. Users have the ability input, display, color, and manipulate the 2D scan slices via a 3D representation. BodyViz is a visualization environment that allows surgeons to plan various types of surgery on their patient data in 3D. BodyViz works with any, DICOM formatted 2D image scan slices. Data can be accessed from internal and external data storage devices, as well as network and CD/DVD data sources. The software runs on any modern Windows based computer (i.e. laptop or desktop) with a 3D graphics card that meets minimum requirements, eliminating the need for specialized hardware. BodyViz is a medical device image software that is used with computer hardware in a typical hospital or clinic networked computer environment. The device does not contact the patient, nor does it control any life sustaining devices. A physician, providing sufficient opportunity for competent human intervention, interprets images and information being displayed.
The provided text does not contain information about acceptance criteria or a study proving that the device meets such criteria. The document is a 510(k) summary for the BodyViz Picture Archiving Communications System, which is a software device for creating 3D models from 2D scan slices.
The relevant sections discuss:
- Device Description: The software's function to input, display, color, and manipulate 2D scan slices into 3D representations for surgical planning.
- Indications for Use: Emphasizes that "Analysis of images and diagnosis is not performed by the software but by physicians or trained professionals." This indicates the device is a visualization tool, not a diagnostic aid that would require performance metrics for accuracy or sensitivity/specificity.
- Technological Characteristics: States it's medical device image software used with computer hardware in a PACS environment.
- Testing: Only mentions "BodyViz software has been tested to DICOM media storage application profiles." This generally refers to technical standards compliance for image handling, not clinical performance.
- Conclusion: Declares substantial equivalence to predicate devices.
Therefore, I cannot provide the requested table and study details because the provided text does not include:
- Acceptance Criteria and Reported Device Performance: No specific performance metrics (e.g., accuracy, sensitivity, specificity, processing time) are mentioned, nor are any thresholds for acceptance.
- Sample size for the test set or data provenance: No clinical study or test set is described beyond DICOM compliance.
- Number and qualifications of experts for ground truth: Not applicable as no clinical ground truth assessment is mentioned.
- Adjudication method: Not applicable.
- MRMC comparative effectiveness study: No such study is mentioned or implied.
- Standalone performance study: No study evaluating the algorithm's performance on its own is described.
- Type of ground truth used: Not applicable.
- Sample size for the training set: Not applicable as no AI/Machine Learning model requiring a training set is explicitly described beyond basic image processing.
- How ground truth for the training set was established: Not applicable.
The device, as described, is a visualization tool. Its "performance" would likely be assessed through its ability to accurately render 3D models from 2D DICOM data, rather than diagnostic accuracy. The testing mentioned only addresses DICOM compliance, which is a technical interoperability standard, not a clinical performance standard.
