Ultrasonic three-dimensional fetal facial contour image processing method system

Abstract

A three-dimensional ultrasonic fetal face profile image processing method and system. The method comprises: S101: detecting a multi-frame slice of fetal volume data in a predetermined direction to acquire a target area in each frame of the slice, the target area comprising a fetal head area; S102: screening out the slice comprising the target area and performing facial boundary detection on the screened-out slice to obtain trusted boundary points; and S103: cropping the fetal volume data according to the trusted boundary points to obtain a three-dimensional ultrasonic fetal face profile image. According to the image processing method, the volume data is cropped by using the trusted boundary points so that a shaded part of the fetal face can be automatically cut out; and thus the operation of a detector is simplified and three-dimensional ultrasonic imaging rate is improved.

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
