The CyberKnife System for Stereotactic Radiosurgery/Radiotherapy is intended to provide treatment planning and image-guided stereotactic radiosurgery and precision radiotherapy for lesions, tumors and conditions anywhere in the body when radiation treatment is indicated.
The CyberKnife System is a computer-controlled medical system for planning and performing minimally invasive stereotactic radiosurgery and precision radiotherapy using a treatment radiation generator, linear accelerator, manipulator (robot), and a target locating subsystem to accurately deliver radiation to the treatment target anywhere in the body.
The provided text does not contain information about specific acceptance criteria or a study proving the device meets those criteria.
The document is a 510(k) summary for the CyberKnife® System, focusing on establishing substantial equivalence to predicate devices. It states that the device's "intended use, principles of operation, and technological characteristics are the same" as the predicate devices, which is the basis for its clearance.
Therefore, I cannot populate the requested table or answer the specific questions about acceptance criteria, study details, sample sizes, ground truth establishment, or MRMC studies.
Here's why the information is missing from the provided text:
- 510(k) Substantial Equivalence: A 510(k) submission primarily demonstrates that a new device is as safe and effective as a legally marketed predicate device. It often relies on comparisons of technical specifications, performance data (if applicable and comparable), and intended use rather than requiring extensive de novo clinical studies with pre-defined acceptance criteria for the new device as would be seen for a PMA (Premarket Approval) application or a novel high-risk device.
- Focus on Description and Intended Use: The provided text mainly describes the device, its intended use, and the regulatory outcome (clearance based on substantial equivalence). It doesn't delve into detailed performance studies.

Dear Ms. Schlagenhaft:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
