AI Technical Summary
Technical Problem
Existing OCT pullback imaging technology suffers from problems such as longer flushing time and poorer image quality when scanning longer blood vessel segments due to increased pullback length.
Method used
By acquiring the OCT pullback image sequence to be stitched, the target areas such as the lumen, vessel wall, and guidewire location are identified, and the images are stitched together based on these areas to obtain stitched OCT pullback images, thus avoiding increasing the catheter pullback length.
Benefits of technology
It improves the image quality of OCT pull-back images, reduces incomplete rinsing, simplifies the operation process, and improves image accuracy.

Abstract
The application provides an OCT pullback image splicing method, a display method, a system and a storage medium. The method comprises the following steps: acquiring at least two OCT pullback image sequences to be spliced; identifying target regions in the at least two OCT pullback image sequences respectively; the target regions comprise at least one of a lumen region, a blood vessel wall position and a guide wire position; and splicing the at least two OCT pullback image sequences according to the target regions in the at least two OCT pullback image sequences, to obtain a spliced OCT pullback image. In the method, the pullback length of the catheter does not need to be increased, and therefore, the flushing operation of a longer blood vessel lumen section is not needed to obtain an OCT pullback image of a longer blood vessel, that is, the phenomenon of incomplete flushing is reduced, and therefore, the image quality of the obtained OCT pullback image is improved.
