Abstract: Techniques are disclosed for measuring the corpus callosum volume of a fetus using magnetic resonance imaging. A scanogram of a fetus is acquired, and a detection area is determined using the corpus callosum position of the fetus in the scanogram. Magnetic resonance scanning is performed on the detection area to obtain a diffusion weighted image, with a gradient direction that is orthogonal or normal to an extending direction of fiber bundles of the corpus callosum. A fetal head image is cropped in the diffusion weighted image, and a predetermined threshold is applied to obtain an image including pixels having a brightness value that is greater than the threshold. Image processing is performed on the binarized image, with the largest region therein being identified as the corpus callosum, and the sum of voxel dimensions associated with the signal of the largest region being calculated as the corpus callosum volume.

The first optical switching switch receives an optical signal, where the optical signal includes a first optical signal and/or a second optical signal. The first optical switching switch sends the first optical signal to the wave-dropping wavelength switching switch. The first optical switching switch sends the second optical signal to the pass-through dimension switching switch. The wave-dropping wavelength switching switch performs wavelength switching on the first optical signal. The wave-adding wavelength switching switch performs wavelength switching on a third optical signal generated locally and sends it to the second optical switching switch.
