Device Description
CerebralGo Plus is a medical image management and processing software package to be used by trained professionals, including, but not limited to physicians and medical technicians. The software runs on standard "off-the-shelf" hardware and can be used for image viewing, and processing images of DICOM compliant CTA imaging which, when interpreted by a trained clinician, may yield information useful in clinical decision making. CerebralGo Plus system provides a wide range of basic image viewing, processing, and manipulation functions, through multiple output formats. The software is used to visualize large vessels from head and neck CTA imaging.
More Information

There are no reference devices in this submission.

Yes
The document mentions "Algorithm training" and "Algorithm testing" with specific details about training and test datasets, including data sources, sample sizes, and annotation protocols. This strongly suggests the use of a trained algorithm, which is characteristic of AI/ML. The performance metrics (Dice coefficient, Hausdorff Distance) are also commonly used to evaluate the performance of segmentation or image processing algorithms, often trained using ML.

No
The device is described as image processing software for viewing and processing medical images, and its intended use is for providing information useful in clinical decision making, not for treating a disease or condition.

No
The "Intended Use / Indications for Use" section explicitly states, "CerebralGo Plus is not intended for primary diagnostic use."

Yes

The device is described as a "software package" that "runs on standard 'off-the-shelf' hardware" and is used for "image viewing and processing." There is no mention of proprietary hardware components included with the device.

Based on the provided information, CerebralGo Plus is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is performed in vitro (outside the body).
  • CerebralGo Plus Function: CerebralGo Plus processes and views medical images (CTA scans) acquired from within the body. It does not analyze biological specimens.
  • Intended Use: The intended use clearly states it's for image processing and viewing of CTA data, not for analyzing biological samples.
  • Device Description: The description reinforces that it's for processing and visualizing medical images.

Therefore, CerebralGo Plus falls under the category of medical imaging software, not an IVD.

No
The provided text explicitly states "Control Plan Authorized (PCCP) and relevant text: Not Found." There is no mention of the FDA having reviewed, approved, or cleared a PCCP for this specific device.

The logo features a stylized letter "M" composed of several overlapping geometric shapes in shades of pink, purple, and blue. To the right of the "M" is a small, solid blue circle, which serves as a visual anchor and balances the composition.

CerebralGo Plus can connect with other DICOM-compliant devices (e.g., Picture Archiving and Communication System (PACS), Workstations, CT Scanners) to receive CTA scans. After processing, results and images can be sent to a PACS via DICOM transfer and can be viewed on a PACS workstation or via a web user interface contained and accessed within a hospital network and firewall.

Algorithm training of CerebralGo Plus has been conducted on images collected from China as training dataset. Algorithm verification has been conducted on US images.

G. PERFORMANCE DATA

The results of software performance testing demonstrate that CerebralGo Plus has met all design requirements and specifications associated with the intended use of the software. All testing has been carried out in compliance with the requirements of 21 CFR 820 and in adherence to the DICOM standard.

Regarding the validation of the algorithm, the test data was used independently from training dataset.

The algorithm testing of CerebralGo Plus has been performed using 141 images collected from US, which covered different gender, age, ethnicity, equipment and CT protocol used to collect images. The information of demographic and equipment distribution was as follows:
