AI-Based Vertically Moving Radiation Image Acquisition System

The Medical Device Division is centered on medical imaging device technology that combines a C-shaped or U-shaped open gantry, vertically moving irradiation structure, multiple low-output irradiation channels, iris-type shielding structure, and AI-based control.

Open gantry and vertically moving image acquisition structure

This technology uses a C-shaped or U-shaped open gantry arranged along part of the examinee’s body circumference and acquires radiation projection data while moving the gantry vertically along the body length.

Multiple radiation emission modules or irradiation channels are distributed around the gantry, so the system is designed to individually control multiple low-output irradiation channels instead of using one central high-output irradiation point.

Open structure: intended to reduce the psychological burden and structural complexity of closed devices

Vertical movement structure: customized image acquisition by section, including head, torso, pelvis, and legs

AI control structure: condition-based control of irradiation position, intensity, direction, timing, and channel opening status

Shielding structure: reduces unnecessary irradiation by adjusting irradiation windows according to body cross-section shape

Simulation

Vertically Moving Scan Simulation

This shows a structure in which a 50 cm curved scan module moves along the body length of the examinee and sequentially scans the head, torso, and leg regions.

A position sensor detects the current height, and the AI-based controller automatically adjusts the dose mode and irradiation channels by body region.

Core Technology Direction

Open Gantry

C-shaped or U-shaped open gantry

Configured to acquire radiation projection data including the rear body area without completely enclosing the entire body circumference of the examinee.

Moving Scan

Vertically moving irradiation structure

As the gantry moves along the body length and acquires data corresponding to each irradiation section, it can be expanded into whole-body or region-specific examination structures.

AI Control

AI-based controller

Controls irradiation conditions and image reconstruction conditions based on body information, irradiation section, examination purpose, and irradiation history.

Operation Flow

1. Body Information AcquisitionAcquires height, body shape, posture, and distance information through footboards, handles, sensors, and related components.

2. Irradiation Section SettingThe AI controller sets irradiation sections along the body length, such as head, torso, pelvis, and legs.

3. Channel-Based Irradiation ControlOpens, blocks, and adjusts output for multiple X-ray, gamma-ray, or combined-radiation irradiation channels by position.

4. Detection and ShieldingThe detector collects projection data, and the iris-type shielding unit limits unnecessary irradiation areas.

5. Image ReconstructionReconstructs internal structure images based on the acquired radiation projection data.

Application Fields

Medical Imaging Devices

Can be reviewed as a device for general radiographic imaging, low-dose examination, and region-specific customized image acquisition.

Nuclear Medicine and Hybrid Imaging

Can be expanded into a combined radiation projection data structure using gamma rays or a combination of X-rays and gamma rays.

Industrial Non-Destructive Testing

The open gantry and moving irradiation structure can be applied not only in medicine but also to non-destructive testing equipment.

Commercialization Considerations

Technical Verification

Step-by-step verification is required to determine whether radiation generation, detection, shielding, movement, and image reconstruction structures are feasible in real environments.

Standards and Safety

Medical device standards such as radiation safety, electrical safety, software validation, and user protection structures should be reviewed.

Patents and Cooperation

Secure rights to the core structure and establish joint development structures with medical imaging equipment manufacturers, research institutes, and medical institutions.
