The MindState Functional Data Acquisition Device (fDAD) is used as a data acquisition tool in functional Magnetic Resonance Imaging (fMRI) procedures based on Blood Oxygen Level Dependent (BOLD) contrast.
fDAD presents a stimulus to the patient and collects the patient's responses from a button device. Execution of specific cognitional tasks by the patient (in response) generates functional data. The fMRI data comprised of the MR images (in DICOM format) sent from the MR scanner control station, and the behavioral response (binary) data are archived to a removable media by fDAD.
The fDAD-PT (fDAD Personal Trainer) is used to train the use of the four button response device and to ensure their understanding and successful execution of the specific task. A short activation task is presented on the fDAD-PT control station to ensure the patient is aware of the nature of the response to be provided.

I am sorry, but the provided text from the FDA 510(k) summary for the "MindState Functional Data Acquisition Device (fDAD)" does not contain the detailed information necessary to describe the acceptance criteria and the study that proves the device meets those criteria.
The document is a letter from the FDA to Neurognostics, Inc., confirming the substantial equivalence of their device to a legally marketed predicate device. It states that the device can proceed to market based on this determination.
Here's a breakdown of why I cannot fulfill your request based on the provided text:
- No Acceptance Criteria or Performance Data: The letter does not specify any performance metrics, thresholds, or acceptance criteria the device needed to meet. It also does not present any results from performance studies.
- No Study Details: The document does not describe any clinical or technical study conducted to support the device's performance. It doesn't mention sample sizes, data provenance, expert involvement, adjudication methods, or ground truth establishment.
- Focus on Substantial Equivalence: The primary purpose of this 510(k) letter is to declare that the device is "substantially equivalent" to a predicate device already on the market. This determination is often based on design, materials, and intended use similarities, rather than requiring extensive new performance data to be submitted for this specific device's approval. While a sponsor typically submits performance data to demonstrate substantial equivalence, those details are not included in this high-level FDA letter.
Therefore, I cannot provide the requested table or answer the specific questions about the study design and results. The provided text simply confirms the regulatory clearance for the device based on its substantial equivalence.

Re: K052571 Trade/Device Name: MindState Functional Data Acquisition Device (IDAD) Regulation Number: 21 CFR 892.1000 Regulation Name: Magnetic resonance diagnostic device Regulatory Class: II Product Code: LNH Dated: September 16, 2005 Received: September 21, 2005
Dear Mr. Gadagkar:
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.
{1}------------------------------------------------
This letter will allow you to begin marketing your device as described in your Section 510(k) I his letter will anow you to ocgin maneting your antial equivalence of your device to a legally premarket nothication. The I DA miding of bassification for your device and thus, permits your device to proceed to the market.

§ 892.1000 Magnetic resonance diagnostic device.
(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
