Improved Heatmap-Based Landmark Detection

Mitral valve repair is a very difficult operation, often requiring experienced surgeons. The doctor will insert prosthetic ring to aid in the restoration of heart function. location prosthesis' sutures critical. Obtaining and studying them during procedure valuable learning experience for new This paper proposes landmark detection network detecting endoscopic pictures, which solves problem variable number suture points images. Because there are two datasets, one from simulated domain other real intraoperative data, this work uses cycleGAN interconvert images domains obtain larger dataset better score on data. performed tests using 2708 photos 2376 mean sensitivity about 75.64% precision 73.62%. 50.23% 62.76%. data AdaptOR MICCAI Challenge 2021, can be found at https://zenodo.org/record/4646979\#.YO1zLUxCQ2x.
