Stent Enhancement: Transforming Cardiovascular Imaging

Stent Enhancement is an advanced imaging technology that combines DSA data with specialized algorithms to generate detailed 3D reconstructions of stented vessels. It provides physicians with clear insights into the stent's position, morphology, and wall apposition, while also assessing critical factors such as full expansion, migration, and restenosis. These insights help guide more accurate treatment planning.

From Early Challenges to Breakthroughs

In the early days of cardiovascular interventions, physicians had to rely on grayscale DSA images to judge whether a stent was fully expanded. The low contrast between the stent and vessel wall made accurate evaluation difficult, leaving decisions heavily dependent on the surgeon's experience.

The 2010s brought progress with conventional stent enhancement, which amplified metallic signals and allowed stents to be "frozen" in a 2D plane. While this was a major step forward, it still lacked the ability to show dynamic stent-wall interactions in real time.

By 2018, real-time stent enhancement marked another leap. With higher frame rates, physicians could watch the stent move within the vessel during procedures-particularly helpful for tandem stents and branching lesions. However, image quality was often compromised by artifacts, leading to blurred visuals.

Today's All-in-One Solution

With the integration of AI and robotics, WeMed Medical's "All-in-One" Stent Enhancement solution now combines three modes-conventional, real-time, and subtraction-into a single platform. While most competitors remain limited to one or two modes, WeMed Medical delivers a complete solution with:

• 10ms image reconstruction
• 99% marker recognition accuracy

This innovation enhances both speed and precision, making it possible to track stents dynamically, reconstruct 3D structures, and simplify clinical workflows.
