4D intracardiac echocardiography imaging system, echocardiography imaging method and echocardiography imaging apparatus

A 4D (four-dimensional) intracardiac echocardiography (ICE) imaging system, at least comprising an interventional catheter, mechanical driving apparatus and an ultrasonic host, wherein the interventional catheter comprises a cavity located at a distal end, and a miniature ultrasonic probe located in the cavity, and the mechanical driving apparatus is arranged at a proximal end of the interventional catheter;

• the mechanical driving apparatus and the ultrasonic host are connected to the miniature ultrasonic probe, respectively;
• the ultrasonic host is used to output an acoustic wave driving signal;
• the miniature ultrasonic probe is used to intermittently emit the acoustic wave driving signal output by the ultrasonic host;
• the mechanical driving apparatus is used to drive the miniature ultrasonic probe to rotate unidirectionally and uniformly inside the interventional catheter when the miniature ultrasonic probe emits the acoustic wave driving signal output by the ultrasonic host, thus performing mechanical 4D scanning imaging on different positions of an imaging target;
• the miniature ultrasonic probe is also used to receive an echo signal of the acoustic wave driving signal, and to transmit the received echo signal to the ultrasonic host;
• and the ultrasonic host is also used to perform signal post-processing on the received echo signal to determine 4D ultrasonic imaging of the imaging target;
• further comprising a torque coil and a catheter-side connector;
• the torque coil is arranged in the cavity of the interventional catheter and fixedly connected to the miniature ultrasonic probe, and the torque coil is fixedly connected to the catheter-side connector, and the catheter-side connector rotates to drive the torque coil and the probe to rotate;
• and the miniature ultrasonic probe, the torque coil and the catheter-side connector are all disposable;
• and
• wherein the mechanical driving apparatus comprises a motor, a multichannel slip ring, and a host-side connector;
• the motor is fixedly connected to a stator of the multichannel slip ring, the host-side connector is fixedly connected to a rotor of the multichannel slip ring, the host-side connector is connected to the catheter-side connector, the motor drives the rotor of the multichannel slip ring to rotate through mechanical transmission, and the motor, the multichannel slip ring and the host-side connector are all reusable.
