Description

Method, system, equipment and storage medium for cardiac interventional operation
Technical Field
The present invention relates to the technical field of cardiac surgery devices, and in particular, to a method, a system, a device, and a storage medium for cardiac interventional surgery.
Background
Ultrasound (US) medicine is a discipline of a combination of acoustics, medicine, optics and electronics. Ultrasonic medicine is an application in the medical field that is researching acoustic technology above audible frequencies. The ultrasonic diagnosis, ultrasonic therapy and biomedical ultrasonic engineering are included, so that the ultrasonic medicine has the characteristics of combining medicine, theory and work, has wide related content and has high value in preventing, diagnosing and treating diseases.
Ultrasonic imaging is to scan a human body with an ultrasonic sound beam, and to obtain an image of an organ in the body by receiving and processing reflected signals. There are a variety of ultrasound instruments in common use: the a type (amplitude modulation type) indicates the intensity of a reflected signal by the amplitude, and an "echo pattern" is displayed. The M-type (spot scanning type) is a graph showing the movement of the spot at different times, with the vertical direction representing the spatial position from shallow to deep and the horizontal direction representing time. Both types are one-dimensional display and have limited application range. Type B (brightness modulation) ultrasonic section imaging instrument, abbreviated as "B ultrasonic". The light spots with different brightness are used for representing the intensity of a received signal, and when the probe moves along the horizontal position, the light spots on the display screen synchronously move along the horizontal direction, and the light spot tracks are connected into a section view scanned by an ultrasonic sound beam, so that the two-dimensional imaging is realized. The D type is made according to the ultrasonic Doppler principle, and the C type displays a cross section sound image perpendicular to the sound beam in a scanning mode similar to a television.
In recent years, ultrasonic imaging techniques have been developed such as gray scale display and color display, real-time imaging, ultrasonic holography, transmission type ultrasonic imaging, ultrasonic co-computed tomography, three-dimensional imaging, intra-body cavity ultrasonic imaging, and the like.
