AI Technical Summary

Technical Problem

Existing endoscopic image processing methods cannot dynamically adapt to the actual scene during surgery, resulting in image contrast distortion, loss of detail, or excessive enhancement of background noise, making it difficult to meet the needs of precise thrombectomy.

Method used

By acquiring images and simultaneously obtaining the working status parameters of the dual-balloon microcatheter, the region is divided into blood vessel, thrombus, and background regions. A dynamic threshold model is established, and an adjustment scheme combining grayscale and color is adopted to adjust the contrast of each region in a targeted manner. Combined with parameters such as balloon inflation pressure and aspiration negative pressure, regional differential adjustment is achieved.

Benefits of technology

It improves the detail of image observation, enhances the clarity of thrombi and blood vessels, and increases the success rate of thrombectomy.
