Indications for Use
Augmento is a web-based PACS and radiology workflow management solution. It receives digital images and data from various DICOM compliant sources (i.e. CT scanners, ultrasound systems, RF Units, PET Units, computed & digital radiographic devices, secondary capture devices, imaging gateways and other imaging sources). Images and data can be stored, communicated, processed and displayed within the system and/or across computer networks at distributed locations. Only preprocessed DICOM "for presentation" images can be interpreted for primary image diagnosis in mammography. Lossy compressed images and digitized film screens of mammographic images must not be reviewed for primary image interpretations. Mammographic images may only be interpreted using a monitor that meets technical specifications identified by the FDA. This system is meant to be used by trained and qualified medical professionals, e.g physicians, radiologists, nurses, and medical technicians.
Device Story
Augmento is a web-based PACS and radiology workflow management system. It ingests DICOM images from various modalities (CT, MR, US, etc.) via a client-side gateway. The system organizes studies into a worklist, enabling radiologists to view, diagnose, and report on images. It provides 2D multi-planar reconstruction (MPR) and maximum intensity projection (MIP) for visualization. The system supports optional integration with FDA-cleared 3rd-party AI models, displaying their outputs "as-is" for clinician review. It is used in hospitals and imaging centers by radiologists and medical staff. The system facilitates communication and workflow management. Clinicians use the viewer to interpret images and AI findings to support clinical decision-making. Data is stored in an RDBMS and object storage, with TLS/HTTPS/AES-encrypted network transmission.
Clinical Evidence
Bench testing only. Testing included risk management (ISO 14971:2019), cybersecurity vulnerability assessment, usability testing (IEC 62366-1:2015), and software verification/validation (unit, integration, and system testing). An angle measurement study compared Augmento to an FDA-cleared viewer (Sotneta MedDream Viewer, K162011) using 12 X-ray scans across four categories (chest, knee, ankle, pelvis). Statistical analysis (equivalence test and T-test) demonstrated equivalent performance in the 0°-180° range. Interface testing confirmed 3rd-party AI model integration does not alter source DICOM file integrity.
Technological Characteristics
Web-based PACS; Windows 10 environment; supports DICOM standards (NEMA PS 3.1-3.20). Features MPR/MIP post-processing, 3D cursor, and optional 3rd-party AI integration. Connectivity via TCP/IP, TLS-based HTTPS with AES encryption. Software lifecycle per IEC 62304; usability per IEC 62366-1. Software level of concern: moderate.
Indications for Use
Indicated for trained medical professionals (physicians, radiologists, nurses, technicians) to store, communicate, process, and display DICOM images (CT, MR, US, RF, PET, DX, CR, NM, MG, RG, XA) for diagnostic analysis. Mammography images require "for presentation" DICOM files and FDA-compliant monitors; lossy compressed or digitized film mammography images are contraindicated for primary diagnosis.

The technological principle for both the subject and predicate devices are the same in terms of Prescription Use, support of various modalities, resolution, image storage, use of DICOM Standard, 3D Cursor, and Operation features. Most of the features, specifications and functions of both the subject and predicate devices like indications for use, software web browser, software intended environment, study viewer, and study worklist are similar.
Auqmento provides the feature of optional integration with external FDA-cleared 3rd party AI models whereas NubeX does not claim to have this feature. The integration with the FDA-cleared 3rd party AI models is optional, based on the user's discretion, and always in accordance with the 3rd party manufacturer's regulatory clearance. Further, Augmento receives the AI output and merely displays the output of the integrated FDAcleared 3rd party AI models, "as-is". Similarly, the Arterys MICA (K203744) device included such an addition with the ability to integrate with 3rd party AI models outputs within their viewer. Hence, the difference does not affect the product effectiveness and safety.

- . Device Hazard Analysis and mitigations, and design considerations pertaining to intentional and unintentional risks associated with Augmento to reduce the risks as per ISO 14971:2019, evidence of Risk-handling activities that may be invoked throughout the life of the device, are detailed.
- . Vulnerability Assessment & Penetration to check whether the security controls are adequately implemented in Augmento to mitigate the cybersecurity risks.
- . Usability testing for verifying and validating the usability of the Augmento user interface to IEC 62366-1:2015 are done.
- . User Acceptance Testing is to test all the features which comply with the intended use of Augmento. The intended use of the software is verified against SRS / SDS documents.
- . Unit Testing is to verify end-to-end workflow-based units encompassing all the major units of the product, ensuring that the unit code is complying with the correctness, and intended use of the product.
- . In Integration testing, end-to-end integration of the different software components covering APIs, external SOUP applications and tools, independent Libraries, etc across all the different features, and functionalities of Augmento are tested. System testing covers all the functional testing for end-to-end working. The functionalities cover, but are not restricted to Configuration and Settings, User management, DICOM viewer and DICOM Acceptor's working, Search operations, Assigning Radiologists, Smart tags operations, Conversation operations, Report Management, Audit Log Management, Error Handling, and Hospital Management
- . Unit testing, Integration & System testing, and User Acceptance Testing (UAT) for which test cases were created and executed. The test cases were addressed and successfully passed the acceptance criteria.
- . Anqle Measurement study was conducted to establish the substantial equivalence of the limit and accuracy of the angle tool of Augmento in comparison with an FDA-cleared DICOM viewer. In the study, an FDAcleared DICOM viewer was used to measure the common angles from different X-ray scans. Replicability was demonstrated by measurements made by two readers in twelve independent X-ray scans from four different categories: frontal chest, AP knee, lateral ankle, and AP pelvis. These measurements were compared to the angles measured using Augmento. Two statistical analysis tests: the equivalence test and T-test were used. The limit of the angle measurement tool of Augmento is observed to be equivalent to the angle measurement tool of FDA-cleared DICOM viewer (Sotneta MedDream Viewer(K162011)) is in the range of 0° and 180°. The results conclude that the two viewers are substantially equivalent.
- . The integration interface between Augmento and 3rd party AI model was tested to confirm that the integrity of the source DICOM file and output from AI models is unaltered and hence, does not get impacted when the source file is sent to the AI model for findings and the AI model sends the output to Augmento through the interface.
The non-clinical testing demonstrates that the subject device performs in accordance with its intended use, complies with the requirements specified in the FDA-recognized consensus standards, software level of concern is "moderate" and meets the acceptance criteria indicating that the subject device does not raise any new safety and/or effectiveness concerns and is substantially equivalent to the predicate.
{11}------------------------------------------------
## The standards applicable as per Recognized Consensus Standards are as below:
- · IEC 62304 Edition 1.1 2015-06 Consolidated Version Medical device software life cycle processes.
- · IEC 62366-1:2015: Medical devices-Part 1: Application of usability engineering to medical devices.
