The MindState Functional Data Acquisition Device (fDAD) is used as a data acquisition tool in the MRI environment to perform functional MRI (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 (response) device. Execution of specific cognitive or motor activation tasks by the patient in response to a set of stimuli creates the necessary behavioral 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 patient in the use of the four button response device and to ensure their understanding and ability to perform the specific task. A short activation task is presented on the fDAD-PT control station and the patient is allowed to become familiar with the nature of the activation task and the nature of the response to be provided.

The information provided does not contain a study or data proving the device met specific acceptance criteria. The document is a 510(k) clearance letter from the FDA for the MindState Functional Data Acquisition Device (fDAD), indicating that the device has been found substantially equivalent to a predicate device. This letter does not typically include detailed performance data or acceptance criteria for a new study.
Therefore, I cannot provide the requested information about acceptance criteria, device performance, sample sizes, ground truth establishment, expert qualifications, or MRMC comparative effectiveness study results from the given text.
The text specifies the Indications for Use:
The MindState Functional Data Acquisition Device (fDAD) is used as a data acquisition tool in the MRI environment to perform functional MRI (fMRI) procedures based on Blood Oxygen Level Dependent (BOLD) contrast. It presents a stimulus to the patient and collects patient responses from a button device. It archives fMRI data (MR images in DICOM format) and behavioral response (binary) data to removable media. The fDAD-PT (Personal Trainer) is used to train patients on the use of the four-button response device and to ensure understanding and ability to perform specific tasks.
§ 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.
