One-Click Autofocus Versus Segmented Focus in Gastric Endoscopy
Sponsor: Shandong University
Summary
Magnifying endoscopy provides high-resolution images that enhance the detection of early gastrointestinal lesions. However, conventional manual zoom techniques require frequent focal adjustments, which can be technically demanding and may compromise image stability, especially in complex anatomical settings. This study evaluates a novel one-click autofocus system based on image recognition and computer vision algorithms. The system automatically adjusts focal distance within seconds, eliminating the need for manual operation. This trial aims to compare the efficiency and image quality of one-click autofocus versus segmented manual focus in patients undergoing magnifying endoscopy for gastric diseases. A tandem randomized controlled trial will be conducted to assess procedure time, image clarity score, and operator satisfaction between the two techniques.

Interventions
One-Click Autofocus
Magnifying endoscopy examination performed using the one-click autofocus mode. The system automatically adjusts focus to the optimal plane with a single button press.
Segmented Focus
Magnifying endoscopy examination performed using the segmented focus mode. The endoscopist manually adjusts the focus level stepwise through multiple pre-set focal planes.
