First Claim
Patent Images
1. A method of providing real-time marker detection in medical imaging of a stent, the method comprising:
- obtaining a plurality of frames of image data;
determining a plurality of candidate markers for the stent in the plurality of frames of image data; and
detecting, by a processor, one or more first markers for the stent from the plurality of candidate markers, the detecting being based on automatic initialization using a subset of frames of image data from the plurality of frames of image data, the detecting performed in real-time with the obtaining.

Abstract
Real-time marker detection in medical imaging of a stent may be provided. A plurality of frames of image data may be obtained. A plurality of candidate markers for the stent may be determined in the plurality of frames of image data. One or more markers from the plurality of candidate markers may be detected. The detecting may be based on automatic initialization using a subset of frames of image data from the plurality of frames of image data. The detecting may be performed in real-time with the obtaining.
