Market Context — Why This Technology, Why Now

The global shift towards decentralized healthcare and digital health solutions is accelerating, driven by demands for greater patient convenience and cost efficiency. Regulatory bodies are also encouraging innovative portable medical devices to improve health equity. This technology aligns perfectly with these trends, offering a robust solution to deploy advanced imaging capabilities beyond traditional hospital settings, thereby transforming medical access and operational paradigms worldwide.

Key Competitive Advantages
01

Reduces Power Consumption by ~70%, Suppresses Heat Generation: A clutch structure and regenerative braking suppress electromotive force in the drive motor and convert inertial energy into electricity. This reduces CT scanner power consumption by up to ~70% and significantly suppresses internal heat generation.

02

Enables Device Miniaturization and Weight Reduction: Lower power consumption and heat generation allow for smaller cooling systems and power units. This reduces the overall device weight and size by approximately 50%, facilitating deployment and transport in standard vehicles.

03

Establishes Exclusive Advantage in a Blue Ocean Market: This pioneering technology had no similar prior art cited by examiners. This exclusive technological advantage offers licensees the potential to shape a new market ahead of competitors and establish a strong, defensible position.
