4D (four-dimensional) ultrasonic probe scanning control method, 4D ultrasonic probe scanning control device and 4D ultrasonic probe scanning control system

Abstract

The invention discloses a 4D (four-dimensional) ultrasonic probe scanning control method, a 4D ultrasonic probe scanning control device and a 4D ultrasonic probe scanning control system. The method includes receiving probe scanning parameters issued by an upper control program, and controlling alternation between sound head movement driven by a motor driving module and image scanning by a sound head control module according to the probe scanning parameters. In the method, the motor driving module does not generate pulse signals when a sound head scans images, so that the pulse signals generated by the motor driving module as well as high-frequency harmonic waves caused by the pulse signals are prevented from interfering ultrasonic echo signals currently received by the sound head. By the method, all scanning lines emitted by the sound head can be on the same plane, deviation between actually received signal positions and expected received signal positions can be reduced, quality of two-dimensional images is improved, and further, quality of three-dimensional images is improved. By the method, dithering of the three-dimensional images during real-time display is also relieved.

Description

technical field [0001] The present invention relates to the technical field of ultrasonic scanning, in particular to a method, device and system for controlling scanning of a 4D ultrasonic probe. Background technique [0002] Traditional medical imaging equipment can only provide two-dimensional images of the inside of the human body. Doctors can only estimate the size and shape of the lesion from multiple two-dimensional images based on experience, so as to imagine the three-dimensional geometric relationship between the lesion and its surrounding tissues. posed difficulties. The 3D visualization technology can reconstruct a 3D shape from a series of 2D images and display it on a monitor. Therefore, not only can the overall concept of the intuitive and image of the imaging object be obtained, but also many important three-dimensional information can be preserved. Because ultrasound imaging has obvious advantages such as non-invasiveness, no ionizing radiation, and flexibl...

[0005] Moreover, when the existing ultrasonic probe scans, the process of transmitting and receiving ultrasonic waves by the acoustic head is carried out simultaneously with the movement of the acoustic head, so the scanning lines of the two-dimensional image formed by the moving acoustic head are not on the same plane. , resulting in a deviation between the actual received signal position and the expected received signal position, making the two-dimensional image blurred and reducing the quality of the two-dimensional image, thereby affecting the quality of the three-dimensional image

[0006] In addition, the reciprocating motion of the sound head usually includes the following stages: forward acceleration, forward constant speed, forward deceleration, reverse acceleration, reverse constant speed, and reverse deceleration. Therefore, when the probe scans forward and reverse The obtained two-dimensional images cannot be completely overlapped at the corresponding positions, resulting in deviations in the synthesized three-dimensional images during forward scanning and reverse scanning, and jitter in real-time display
