Example Embodiment

[0025] In order to apply four-dimensional probes from different manufacturers, the present invention proposes a four-dimensional ultrasound probe (hereinafter referred to as four-dimensional probe) driving method and device. According to different types of four-dimensional ultrasound probe hosts, the initial value D1 of the counter in the controller is issued through the bus. (The initial value of the counter D1 determines the motor speed. Changing the initial value of the counter D1 can meet the speed requirements, which will be described in detail below), the number of pulses in the variable speed zone, the number of pulses in the constant speed zone, and the output power can be used for probes from different manufacturers the goal of. Among them, the initial value D1 of the counter in the controller is determined according to the internal gear ratio GR and rotation speed of different probes.

[0026] Such as figure 1 As shown, the four-dimensional ultrasound probe is connected...

Abstract

The invention discloses a four-dimensional ultrasonic probe drive method. The method includes the steps: a four-dimensional ultrasonic probe is connected with a system master of an ultrasonic imaging system through a probe connector, and the system master drives the four-dimensional ultrasonic probe to move through a drive device; according to the gear ratio and speed requirements of different types of four-dimensional ultrasonic probes, the system master issues an initial value D1 to a counter of a controller in the drive device through a bus; the system master changes the initial value D1 of the counter, so that the drive device outputs corresponding output pulse frequency to a step motor in the four-dimensional ultrasonic probe, and the speed of the step motor is controlled to drive the four-dimensional ultrasonic probe. The method and the device have the advantages that the different probes and speeds can be set and controlled in such manner of downloading parameters through the system bus so that the probes from different manufacturers are adapted; the control manner is simple and effective.

Description

technical field [0001] The invention relates to an ultrasonic imaging control technology, in particular to a four-dimensional ultrasonic probe driving method and device. Background technique [0002] In an ultrasound imaging system, the image obtained by a common probe is a two-dimensional image. To obtain a four-dimensional image, a special ultrasound probe, a four-dimensional ultrasound probe (hereinafter referred to as a four-dimensional probe), is required. The four-dimensional ultrasonic probe is composed of an ordinary ultrasonic transducer plus a stepping motor and a transmission device. When the motor drives the transmission device to make the ultrasonic transducer oscillate around an axis, during the oscillating process of the ultrasonic transducer, the transmitting module applies a transmitting voltage to the ultrasonic transducer to make it emit ultrasonic waves, and when the ultrasonic waves propagate in the human body, Reflections will be generated on uneven su...
