The NDOHD system is intended for viewing, acquiring, recording, archiving and retrieving video and still images of endoscopic and fluoroscopic procedures. The professionals or practitioners using this system would be medical doctors or clinicians such as speech pathologists. The device is a prescription device. The NDOHD system is not intended to be used in an environment that requires sterilization.

The NDOнd High Definition Imaging System (NDOнD) previously acquired FDA clearance in 2013 as a Class II picture archiving and communication system that provides capabilities related to the acquisition, transfer, display, storage, and digital processing of images and videos (K131873). Altaravision replaced off the shelf hardware components due to the hardware becoming obsolete. Altaravision also updated the NDOHD software to enable use of the new hardware, improve the software user interface and conform to Apple's latest coding best practices.

The provided text is a 510(k) Summary for the Altaravision, Inc. NDŌHD High Definition Imaging System (NDOHD). This submission is for a modification to an already cleared device (K131873), primarily due to hardware obsolescence and software updates. It is a Picture Archiving Communications System (PACS) device.

Key takeaway: This is a 510(k) submission for an updated version of a previously cleared PACS device. The core of the submission is to demonstrate substantial equivalence to the predicate device, not to prove clinical efficacy through a new clinical trial against defined acceptance criteria for a novel AI algorithm.

Therefore, many of the typical questions regarding acceptance criteria for AI/ML devices and their associated studies (e.g., sample size for test sets, number of experts, adjudication methods, MRMC studies, standalone performance, ground truth for training) are not directly applicable or explicitly detailed in this type of submission, as the device is not an AI/ML diagnostic or assistive tool in the way that those questions imply. The testing described is primarily for software verification, system validation, and electrical safety, ensuring the new hardware and software function as intended and are as safe and effective as the predicate device.

However, I will extract relevant information where possible and explicitly state when a requested piece of information is not present or applicable.

Acceptance Criteria and Study to Prove Device Meets Criteria

Given that this is a 510(k) for an updated PACS system, the "acceptance criteria" are primarily related to demonstrating substantial equivalence to the predicate device (NDŌHD High Definition Imaging System, K131873) in terms of intended use, indications for use, technological characteristics, and safety and effectiveness. The "study" is the collection of verification and validation testing performed.

1. Table of acceptance criteria and the reported device performance:

Since this is a substantial equivalence submission for a PACS device update, the "acceptance criteria" are not presented as numerical performance targets (e.g., sensitivity, specificity) for a diagnostic task. Instead, they are implied through direct comparison to the predicate device across various characteristics and verification/validation testing. The performance is essentially reported as "equivalent" or "identical" to the predicate, with differences not affecting intended use, safety, or effectiveness.
