Industry Overview - The digital subtraction angiography (DSA) system is an advanced medical imaging system that combines X-ray imaging and computer processing technology to clearly display vascular structures and diagnose vascular diseases. The global DSA market is projected to reach USD 7.974 billion by 2031, with a compound annual growth rate (CAGR) of 7.18% in the coming years [3]. Key Driving Factors - **Aging Population and Disease Burden**: The acceleration of aging in China and the rising incidence of cardiovascular diseases (such as coronary heart disease and stroke) are driving the demand for DSA in interventional surgeries. DSA applications are expanding from cardiology to neurosurgery and oncology, with neurosurgical procedures becoming the fastest-growing segment [5]. - **Policy Support for Domestic Substitution**: The Chinese government is encouraging the localization of high-end medical equipment through policies like the "Healthy China 2030" plan, which includes special funds and tax incentives. Domestic technology breakthroughs and cost optimization are leading to increased market share for local DSA devices [5]. - **Technological Integration and Smart Upgrades**: The integration of artificial intelligence (AI) and 3D reconstruction technology is enhancing diagnostic efficiency, enabling automatic vessel recognition and low-dose imaging, thus promoting the development of DSA towards precision and minimally invasive procedures [5]. - **Global Market Expansion**: Domestic companies are accelerating technology exports to emerging markets in Asia-Pacific and the Middle East through EU CE certification and international cooperation models [6]. Major Obstacles - **Dependence on Core Components**: High-end DSA devices rely on key components such as flat detectors and high-pressure generators. Although domestic companies have made progress in detectors, they still lag behind international giants in critical technologies [7]. - **Patent Barriers**: Domestic companies may encounter patent infringement lawsuits during R&D, and the uncertainty of technological innovation poses risks [8]. - **Rapid Product Updates by International Brands**: International brands release new products every 2-3 years, leading to potential obsolescence of domestic devices [8]. - **High Maintenance Costs**: The maintenance costs for DSA equipment are high, and domestic companies have insufficient service network coverage compared to international brands [8]. Industry Development Opportunities - **Government Support for Localization**: The National Health Commission's guidance on promoting the localization of high-end medical equipment includes funding and tax incentives for domestic technology R&D [9]. - **Expansion of DSA Equipment in County Hospitals**: The "Thousand County Project" aims for 90% of county-level hospitals to be equipped with DSA devices by 2027, with central government subsidies covering 30%-40% of procurement costs [9]. - **Accelerated Approval for Innovative Devices**: The introduction of special approval procedures for innovative medical devices with integrated AI functions is expected to shorten approval times by 30% [9]. - **Mandatory Radiation Safety Certification**: New regulations require reduced radiation doses, prompting upgrades to low-radiation technologies [9].
