The software runs on standard "off-the-shelf" hardware and can be used for image viewing and processing. Data and images are acquired through DICOM compliant imaging devices. CerebralGo Plus provides viewing and processing capabilities for imaging datasets acquired with adult's CTA (CT Angiography). CerebralGo Plus is not intended for primary diagnostic use.

Device Story

CerebralGo Plus is a software-only medical image management and processing system. It receives DICOM-compliant CTA imaging data from hospital networks (PACS, CT scanners). The software processes these images to visualize large vessels in the head and neck. It operates on standard off-the-shelf hardware within a clinical/hospital environment. Trained clinicians use the software to view and manipulate images, which may assist in clinical decision-making. The device does not perform primary diagnosis. It facilitates workflow by providing automated image processing capabilities, potentially improving the efficiency of vessel visualization for clinicians.

Clinical Evidence

Bench testing only. Performance validated using 141 US-collected CTA images across diverse demographics (age, gender, ethnicity) and equipment (GE, Siemens, Philips, Toshiba). Reference standard established by 3 radiologists. Results: Dice coefficient 0.942, 95% Hausdorff Distance 3.692. Subgroup analysis performed for equipment, gender, and age. No clinical performance data used for substantial equivalence determination.

Technological Characteristics

Software-only medical image management and processing system. Runs on standard off-the-shelf physical/virtual servers. DICOM-compliant. Connectivity via hospital network/PACS. No energy delivered to patients. Algorithm verification performed on US datasets.

Indications for Use

Indicated for use by trained professionals (physicians, medical technicians) for viewing and processing adult CT Angiography (CTA) imaging datasets. Not intended for primary diagnostic use.

Regulatory Classification

Identification

Image /page/5/Picture/0 description: The image shows a stylized logo with an abstract design. The logo features a series of connected shapes in varying shades of purple, blue, and teal. The shapes are arranged to resemble a stylized letter 'M' or a mountain range, with a small dot to the right of the main structure.

{6}------------------------------------------------

Image /page/6/Picture/0 description: The image shows a logo with two stylized, connected shapes that resemble the letter 'M'. The shapes are formed by rounded, parallel lines in a gradient of colors, transitioning from pink and purple on the left to blue and teal on the right. A small, solid teal circle is positioned to the right of the shapes, adding a subtle accent to the overall design. The logo has a modern and abstract appearance.

## 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:

| Demographic information | | Quantity |
|-------------------------|--------|----------|
