Problems solved by technology

[0006] For the guidance and monitoring of myocardial radiofrequency ablation, although the real-time two-dimensional ultrasound B images used by ICE can provide information on cardiac cavity structure and tissue morphology, it is difficult to accurately locate the lesion area and the actual ablated area based on this
Although the use of magnetic resonance temperature imaging can realize quasi-real-time monitoring of the ablation process, it requires high equipment, complicated operation and high cost
For the measurement of mechanical parameters of in vivo cardiac tissue, due to the position of the heart, it is difficult for existing in vitro ultrasound methods to flexibly and accurately perform large-scale and multi-dimensional mechanical measurements of in vivo cardiac tissue

Description

technical field [0001] The present invention relates to the field of medical imaging, and in particular, to an intracardiac multimodal ultrasound imaging method, device and system. Background technique [0002] Intracardiac echocardiography (ICE) is a technique for real-time imaging of intracardiac structures by placing a catheter containing an ultrasound probe into the heart chamber through a blood vessel. Compared with conventional in vitro cardiac ultrasound imaging, ICE can help doctors to see the structure of the heart cavity more clearly and intuitively, and is often used to guide myocardial radiofrequency ablation (RFA) to treat atrial fibrillation and other arrhythmias. . [0003] However, the real-time 2D ultrasound B image used by ICE can only provide information on the structure and tissue morphology of the cardiac cavity, and it is difficult to accurately control the position and size of the ablation site and the process of ablation for guiding myocardial radiof...
