  • Patent number: 12239355
    Abstract: An electrophysiological catheter and an ablation system comprising a control device, an ablation energy output device and the electrophysiological catheter. The control device controls the ablation energy output device to selectively provide a first fluid or a second fluid that is a frozen liquid to the electrophysiological catheter. When the ablation energy output device provides the first fluid, the control device controls a first heating component on the electrophysiological catheter to work to heat the fluid entering the electrophysiological catheter for spraying a thermal ablation gas onto the inner surface of a balloon; and when the ablation energy output device provides frozen liquid, the control device controls the first heating component not to work to directly spray the frozen liquid to the inner surface of the balloon.

  • Publication number: 20230230230
    Abstract: The present disclosure relates to an image processing method, a storage medium and a mapping system. An imageological image including a plurality of tomographic images is acquired. A three-dimensional reconstruction is performed according to the plurality of tomographic images to obtain a three-dimensional image model. The three-dimensional image model includes a three-dimensional myocardial fibrosis region image. A three-dimensional electroanatomic model including a three-dimensional abnormal myocardial tissue image is acquired. Since there is a certain correlation between an abnormal myocardial tissue region in the three-dimensional electroanatomic model and myocardial fibrosis, the three-dimensional image model and the three-dimensional electroanatomic model are registered, and an overlapping part of the three-dimensional myocardial fibrosis region image and the three-dimensional abnormal myocardial tissue image is determined as the location of a lesion.
