Driving method for three-dimensional probe in three-dimensional/four-dimensional ultrasonic imaging system

Abstract

The invention discloses a driving method for a three-dimensional probe in a three-dimensional / four-dimensional ultrasonic imaging system. The driving method is used for driving and controlling a stepping electric motor of the three-dimensional probe, and comprises the following steps of selecting the model of the three-dimensional probe of the three-dimensional imaging system; setting electrical and mechanical structure parameters of the three-dimensional probe; setting application parameters of the three-dimensional imaging system; initializing a control model; calculating parameter values needed in the control process according to the parameters of the system and the probe; and carrying out operational control according to the model of a control state machine. The driving method for the three-dimensional probe in the three-dimensional / four-dimensional ultrasonic imaging system has good compatibility and control performance, and can be suitable for a three-dimensional probe of a stepping electric motor in any model, by means of sine control impulse and an electrical control subdivision method, vibration of the probe is greatly reduced, and interference of relatively-large power driving harmonic waves on system signals is greatly reduced.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging, in particular to a driving method of a three-dimensional probe in a three-dimensional / four-dimensional ultrasonic imaging system. Background technique [0002] Ultrasonic imaging is a routine imaging diagnostic method in clinical medical treatment because of its advantages of no radiation, convenient use, and low price. The traditional B-ultrasound imaging system obtains two-dimensional cross-sectional images in the human body. The doctor holds and moves the probe to continuously obtain cross-sectional images of different positions in the human body, and reconstructs the overall state of tissues and organs in the human body diagnosis area in the brain. With the development of computer technology and faster data processing speed, three-dimensional / four-dimensional ultrasound imaging has gradually become a reality and applied to clinical diagnosis. [0003] At present, the volumetric probes used ...
