Problems solved by technology
However, real-time DSA usually can only obtain two-dimensional imaging, which cannot meet the needs of three-dimensional positioning; (2) using magnetic field positioning technology, this solution requires the use of magnetic field generators and receivers, and the cost is high; (3) using electric field positioning technology, This solution needs to integrate multiple discharge electrodes on the catheter and receive electrical signals outside the human body, which not only has low precision, but is also susceptible to interference from human electrophysiological signals

The invention discloses an acoustic positioning method and system, a readable storage medium and terminal equipment. The acoustic positioning method comprises the following steps: acquiring emission time of an acoustic emission module for emitting an acoustic signal and receiving time of each acoustic receiving module for receiving the acoustic signal; determining a time difference between the transmitting time and each receiving time; determining the distance between the acoustic transmitting module and each acoustic receiving module according to the time difference and the sound transmission speed; and calculating the three-dimensional coordinate of the acoustic transmitting module according to the distance and the three-dimensional coordinate of each acoustic receiving module. The acoustic emission module is integrated in the human body catheter and is matched with the acoustic receiving module outside the human body, three-dimensional positioning can be accurately carried out on the acoustic emission module in real time, then the position of the catheter is determined, the safety and accuracy of a cardiovascular interventional operation are improved, the cost is low, and the system is simple.
Description
technical field [0001] The present application relates to the field of acoustic technology, and in particular, to an acoustic positioning method, system, readable storage medium, and terminal device. Background technique [0002] Cardiac disease is an important human disease, including valve disease (eg, valve stenosis and arrhythmia), arrhythmia (eg, atrial fibrillation, atrial flutter), myocardial hypertrophy, and the like. Minimally invasive catheter interventional therapy is currently one of the safest and most effective ways to diagnose and treat these heart diseases, such as endocardial mapping, ablation, ablation of myocardial hypertrophy, and intracardiac echocardiography (ICE) structural imaging. When performing intracardiac catheter intervention, it is necessary to determine the three-dimensional spatial position of the catheter in real time for accurate surgical guidance and three-dimensional modeling. Therefore, accurate positioning of the catheter is the premis...
