Ultrasonic 3d fetal facial contour image processing method and system

Abstract

The invention discloses an ultrasonic 3d fetal facial contour image processing method and system. The method comprises the steps that multiple frames of slices of the fetal body data in the preset direction are tested and the objective area of each frame of slice is obtained, wherein the objective area comprises a fetal head area; the slices of the objective area are screened out, and the facial boundary tests are performed on the selected slices so as to obtain a credible boundary point; the fetal body data is clipped according to the credible point to obtain the ultrasonic 3d facial contour image. The system uses credible boundary point clipping data and automatically clips the shielding part of the fetal face, so that the test human operation is simplified and the ultrasonic 3d plotting rate is increased.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to an ultrasonic three-dimensional fetal facial contour image processing method and system. Background technique [0002] The 3D ultrasound imaging system is based on the traditional 2D ultrasound, which collects multiple sequential spatial sequences of 2D ultrasound images, and reproduces the volumetric data through steps such as scan conversion according to the spatial position relationship of data collection. The three-dimensional ultrasound imaging system provides high-level one-dimensional spatial information that cannot be provided by traditional two-dimensional ultrasound, making clinical diagnosis and observation more intuitive and flexible, and smoother communication between doctors and patients on diagnosis results. Because of its rich and intuitive information, the 3D ultrasound imaging system is currently mainly used for observation of fetal morphology in the ...

Problems solved by technology

However, due to the particularity of the imaging environment, when performing 3D visualization of the fetal face, the front of the fetal face may be blocked by the placenta, umbilical cord, arms, uterine wall, etc., so that the collected 3D volume data may include placenta, amniotic fluid suspension Substances, umbilical cords, uterine tissues, etc. will block the imaging target and make it difficult to observe the target

[0003] Although there is usually an interactive volume cutting method on the current ultrasonic inspection equipment that can provide the inspector to cut the occluded part, but the operation is cumbersome and time-consuming
