Intended Use

The BrainView QEEG Software Package is to be used by qualified medical or clinical professionals for the statistical evaluation of the human electroencephalogram (EEG).

Device Story

BrainView QEEG Software Package performs post-hoc statistical analysis of resting digital EEG data. Input consists of artifact-free, eyes-closed or eyes-open EEG recordings transferred from a host system. The software applies Fast-Fourier Transformation (FFT) to extract spectral power for delta, theta, alpha, and beta frequency bands. It derives over 4,000 measures, including absolute/relative power, asymmetry, and coherence for 19 monopolar and 171 bipolar derivations. These are compared against an age-regressed, Gaussian-validated normative database to generate Z-scores. Results are presented as statistical tables and topographical brain maps. Used in clinical settings by qualified medical personnel, the output serves as a supplementary tool for patient evaluation. It is contraindicated for use as a standalone diagnostic system; clinicians must review traditional EEG and selected epochs to avoid diagnostic errors. The device benefits patients by providing quantitative, age-matched normative comparisons to assist clinical decision-making.

Clinical Evidence

Bench-only validation using clinically acquired EEG waveforms from a small sample of subjects across the 4-85 age range. The study compared Z-scores for absolute power generated by the subject device against the predicate (K041263). Acceptance criteria required an R-squared factor of 0.8 or better. Results confirmed that the subject device produces results in agreement with the predicate across 23 age-grouped sets of Z-scores.

Technological Characteristics

Software-based QEEG analysis tool. Implements Fast-Fourier Transformation (FFT) for spectral analysis (1-40 Hz). Features include Z-score calculation and topographical mapping for 19 monopolar and 171 bipolar derivations. Normative database includes 2303 subjects (eyes-closed) and 1965 subjects (eyes-open) aged 4-85. Developed per IEC 62304:2015. Software level of concern: Moderate.

Indications for Use

Indicated for qualified medical or clinical professionals to perform post-hoc statistical evaluation of human EEG in patients aged 4-85 years.

#### a5 DESCRIPTION OF THE DEVICE:

BrainView QEEG Software Package is a software program for the post-hoc statistical analysis of the human electroencephalogram (EEG). EEG recorded on a separate device (i.e., the host system) is transferred to the BrainView QEEG software package for display and user-review.

The device herein described consists of a set of tables that represent the reference means and standard deviations for representative samples. These tables are implemented as computer files that provide access to the exact tabular data resource for use by software that uses the tables as an information resource. The system requires that the user select reliable samples of artifact-free, eyes-closed or eyes open, resting digital EEG for purposes of analysis.

Analysis consists of the Fast-Fourier Transformation (FFT) of the data to extract the spectral power for each of the designated frequency bands (e.g. delta, theta, alpha, and beta), and frequency information from the EEG. The results of this analysis are then displayed in statistical tables and topographical brain maps of absolute and relative power asymmetry, and coherence for 19 monopolar and 171 selected bipolar derivations of the EEG.

In all over 4,000 measures are derived for comparison against carefully constructed and statistically controlled age-regressed, normative database in which the variables have been transformed and validated for their Gaussian distribution.

Each variable extracted by the analysis is compared to the database using parametric statistical procedures that express the differences between the patient and an appropriate age-matched reference group in the form of z-scores.

The BrainView QEEG Software Package is intended for prescription use by qualified medical personnel.

The device is intended for use by qualified medical personnel only and qualifies for exemption per 21 CFR 801 Subpart D Prescription devices.

#### b1 NON-CLINICAL TESTING:

Non-clinical performance testing included delta, theta, alpha, and beta comparison of the subject and predicate device using a variety of simulated signals which were analyzed for frequency and power. These performance data demonstrated confirmation of pre-specified, objective evidence to specify that output requirements for the software have been fulfilled and met through static and dynamic analyses and code and document inspections. The software testing performance data further established that the software device's specifications consistently conform to the pre-specified user needs and the intended use. The algorithms and statistical methods used for data analysis were also evaluated through these tests. Therefore, the testing demonstrated the that the system accurately translates and presents EEGs from patients.

Potential adverse effects of the device are known if the BrainView QEEG software package is used as a standalone diagnostic system in the absence of other clinical data from more traditional means of patient evaluation. Relying only upon the use of a single index (such as relative power or the topological maps alone) without reviewing the traditional EEG, the epochs selected for analysis, or the complete set of statistical summary tables is also contraindicated and a source of potential error. Additional sources of error could arise from the inappropriate selection of EEG (selecting EEG epochs with artifacts, or by purposely selecting conditions for testing other than those specified). Additionally, it is possible that errors will occur through the purposeful falsification of symptoms in the patient history and patient age.

### Referenced Standards and Performance Testing:

The BrainView QEEG Software Package was developed using:

- IEC 62304:2015 [Edition 1.1] Medical device software — Software life cycle processes
## Software Verification and Validation Testing

Software verification and validation testing were conducted following the FDA guidance document for software contained in medical devices. The software was considered to be a "moderate" level of concern since a failure or latent flaw could indirectly result in a minor injury to the patient through incorrect or delayed information or through action of the operator.

#### b2 CLINICAL TESTING:

Clinical testing of the subject device included the use clinically acquired EEG waveforms from selected subjects who were used to validate performance of subject device database to that of the predicate K041263. These subjects were adequate to provide a range of values of the databases to verify performance since they are part of the adult and pediatric range of ages as well as the frequencies within the databases.

Acceptance criteria were defined as the BrainView QEEG software produces results sufficiently in agreement with the predicate device and that the R-squared factor shall be 0.8 or better. Additionally, the observed range of results obtained from the predicate device shall be used to verify that the BrainView QEEG produces results in agreement with the results obtained from the predicate device. The pre-defined acceptance criteria were met as 10-minute EEG recordings for eyes closed and eyes open of the subjects were de-artifacted and used to calculate z-scores for absolute power for the subject and predicate databases. Although the sample size was small, it was possible to validate results by computing values for all discrete ages ranging between 4 and 85, resulting in 23 age grouped sets of Z-scores for each subject's EEG sample which were compared with the predicate device's output and found to be similar.

#### b3 CONCLUSIONS:

The BrainView QEEG software has the same intended use as the predicate device, and it has the same manner of use and function, being a software-based database. Furthermore, it has similar requirements for training and expectations of intended users. The systems have equivalent performance in terms of data sampling and accuracy in the reference norms across age. Based on the device description, IFU, and performance testing, the BrainView QEEG software package is substantially equivalent to the predicate.
