Systems and methods for fetus monitoring

A method for fetus monitoring, implemented on a computing device having at least one processor and at least one storage device, the method comprising:

• obtaining ultrasound data relating to a fetus collected by an ultrasound imaging device;
• generating at least one 4D image of the fetus based on the ultrasound data;
• directing a display component of a virtual reality (VR) device to display the at least one 4D image to an operator;
• detecting motion of at least part of the fetus based on the ultrasound data;
• and
• directing a haptic component of the VR device to provide a feedback force with respect to the motion to the operator, wherein the at least one 4D image includes a first 3D fetus image and a second 3D fetus image captured prior to the first 3D fetus image, and the detecting the motion of the at least part of the fetus based on the ultrasound data includes:
• determining a vertex correspondence between a plurality of first vertexes of a first mesh surface and a plurality of second vertexes of a second mesh surface, the first mesh surface representing the first 3D fetus image, and the second mesh surface representing the second 3D fetus image;
• and
• for each of the plurality of first vertexes, determining motion information from its corresponding second vertex to the first vertex based on the vertex correspondence, wherein the at least one processor is configured to direct the system to determine a magnitude of the feedback force by:
• determining a target area of the at least one 4D image;
• determining, among the plurality of first vertexes, a plurality of target first vertexes in a portion of the first mesh surface that corresponds to the target area;
• for each of the plurality of target first vertexes, determining a magnitude of a vertex force based on motion information of the target first vertex, the motion information of the target first vertex relating to the motion of the at least part of the fetus;
• and
• determining the magnitude of the feedback force based on the magnitudes of the vertex forces of the plurality of target first vertexes.
