    Intended Use

    The Z-Robot™ Patient Positioning System is an electro-mechanical robotic arm for patient positioning in radiotherapy and medical imaging. It is designed for positioning a patient with a high degree of accuracy and repeatability.

    Device Description

    The Z-Robot™ Patient Positioning System (hereinafter referred to as Z-Robot™) is an electro-mechanical robotic arm with the motion capability in six degrees of freedom. These axes allow the couch to be precisely positioned translationally and rotationally within the specified movement limits. Therefore, Z-Robot™ could be used to accurately position patient in radiotherapy and medical imaging.

    AI/ML Overview

    The requested information is contained within the provided text. The device in question is the "Z-Robot™ Patient Positioning System", which is an electro-mechanical robotic arm for patient positioning in radiotherapy and medical imaging. The acceptance criteria and the study that proves the device meets these criteria are primarily based on non-clinical testing.

    Here's a breakdown of the requested information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly provide a "table of acceptance criteria and reported device performance" for all tests. However, it lists the performance parameters tested and indicates that "All test results were acceptable per the acceptance criteria detailed in the corresponding protocol and test report." It also provides a direct comparison to the predicate device for several key performance metrics, implying these are the relevant acceptance criteria for substantial equivalence.
