AI-MRI

•Product introduction

AI-MRI is an intelligent brain MRI interpretation system that integrates edge/cloud computing technologies with medical imaging AI analysis.

Designed for neurological conditions such as stroke, brain tumors, and AVMs, the system provides structured and multi-stage diagnostic support to improve clinical efficiency and reading accuracy.

AI – MRI

• Main characteristics

Supports DICOM imaging format, compatible with both Web and App platforms
Automated classification and reconstruction of multiple MRI sequences (T1w, T2w, DWI, etc.)

Three-stage imaging analysis with abnormality triage mechanisms
Co-designed and validated in collaboration with clinical physicians

• Core Modules

AI-Atlas
Brain Functional Region Segmentation Module

The AI-Atlas module provides structured segmentation of functional brain regions using standardized anatomical atlases such as DKT Atlas.The visualized results assist clinicians in identifying disease-related or function-critical regions (e.g., language areas, motor cortex) and understanding their spatial relationships.This supports neurosurgical planning, risk assessment, and preoperative evaluation.

Abnormality Triage System
Emergency Case Prioritization Module

After completing AI-based imaging analysis, this module prioritizes emergency cases by evaluating lesion characteristics such as size, location, severity, and involvement of critical functional zones.
It automatically generates risk scores and highlights high-risk cases at the top of the examination list, enabling clinicians to quickly focus on urgent diagnostic needs.
Outputs include multi-modal indicators such as lesion distribution, severity maps, and prioritization rankings, helping physicians accelerate emergency clinical decision-making.

AI-AVM

AI – AVM

• Product introduction

Supporting physicians in the precise planning of brain radiotherapy
Improving Clinical Decision-Making Efficiency and Accuracy

AI-AVM is a cloud-based intelligent medical software designed specifically for patients with arteriovenous malformations (AVM).

By integrating T2-weighted MRI and TOF (Time-of-Flight) MRA, the system automatically performs lesion contouring, tissue segmentation, and preliminary surgical risk stratification.

These imaging analysis capabilities enable radiologists, neurosurgeons, and oncology teams to quickly understand lesion characteristics and spatial relationships during radiotherapy planning.

Powered by deep learning, AI-AVM precisely segments the nidus, normal brain tissues, and cerebrospinal fluid (CSF), and computes quantitative metrics such as volume and tissue proportions—providing an objective foundation for treatment planning.

The system also supports Spetzler-Martin grading, generating AVM size-related scores based on imaging features, while allowing clinicians to supplement location and venous drainage information to complete the grading process.

All analytical results are fully visualized and can be exported as DICOM-RT structure sets (RTSS) for seamless integration with downstream planning workflows and multidisciplinary team communication.

AI-AVM serves as a clinical decision-support tool, and all analytical outputs require final confirmation and necessary adjustments by qualified medical professionals.

Although the system is not intended for diagnostic use, it significantly enhances the efficiency and safety of radiotherapy planning, helping clinicians anticipate treatment risks and potential toxicities.

AI-AVM is a powerful enabler on the path toward precision medicine and intelligent medical imaging analysis.

• Indications for Use

01

AI-AVM is intended for the automatic labeling, visualization, and volumetric quantification of segmentable brain structures and lesions from a set of MRI images.
The system is used by trained medical professionals and serves as an assistive tool for structural MRI assessment.
All outputs require final review and any necessary adjustments by qualified clinicians.
Clinical decision-making and patient management should not rely solely on the results provided by this system.

02

This system is designed specifically for patients with unruptured cerebral arteriovenous malformations (AVM).
It is suitable for patients who have previously undergone Gamma Knife radiosurgery as well as those who are scheduled to receive radiotherapy.

03

By importing T2-weighted MRI and TOF images, the system automatically performs image alignment and overlay processing, reducing the need for clinicians to manually switch between different imaging sequences.
The AI model automatically labels suspected lesion locations and clearly differentiates tissue types:
Red: Nidus (lesion vessels)
Green: Normal brain tissue
Blue: Cerebrospinal fluid (CSF)

04

The system also provides lesion volume, distribution ratios, recommended radiation dose references, and maximum lesion diameter, serving as important parameters for surgical planning and risk assessment.
Clinicians can use the interactive image viewer—supporting rotation and zoom—to quickly inspect ROI regions.
All analysis results can be exported as Excel reports or image snapshots for clinical communication or medical record documentation.

Notice

AI-AVM is an assistive medical imaging analysis system and does not provide diagnostic results.
All analytical outputs are intended for reference by qualified medical professionals only.
Lesion segmentation results generated by the system must be reviewed and interpreted by physicians with anatomical expertise, such as radiologists, neurosurgeons, or neuroradiologists.
The system is designed exclusively for use with T2-weighted MRI and TOF MR angiography in the evaluation of cerebral arteriovenous malformations (AVM).
It is not intended for use in the following circumstances:
Lesions with a maximum diameter smaller than 2 mm
Poor imaging quality
Presence of hemorrhage
Lesions located in or adjacent to the leptomeningeal (pial) region
Before use, medical professionals must ensure that the imaging data meets the system’s analytical requirements and specifications.
