Embodiment 1
[0033] The auricle is mostly composed of cartilage, and is generally bilaterally symmetrical. It is shaped like a shell and forms an angle of about 30° with the skull. At the 20th week of embryonic development, the shape of the auricle is similar to an adult. The position of the auricle was initially low when it was formed, which is equivalent to the upper part of the future neck. With the development of the mandible, the position of the auricle gradually rises to about the height of the flat eyes on both sides of the head. If this developmental obstacle occurs, you can Forms lower ears.
[0034] Lower ears can be found in Alpert syndrome, DiGeorge syndrome, Pierre syndrome, trisomy 21, etc., and are common in inherited middle ear malformations, inner ear malformations caused by multiple chromosomal aberrations, and loss of inner ear hair cells. Two-dimensional ultrasound cannot display the auricle and eye of the fetus at the same time on one slice, so it is very easy to miss the...
Embodiment 2
[0049] In some embodiments, in the step S102, before separately acquiring and saving the left and right face three-dimensional images displayed on the same screen by the left ear and left eye, right ear and right eye, it may also include correcting the fetus Steps for facial image to horizontal position.
[0050] After acquiring the 3D ultrasound image of the fetal face, due to the position of the fetus, the 3D image of the fetus displayed on the screen may be tilted. When the fetus is tilted, it may cause trouble in the subsequent steps or cause inaccurate measurement. Therefore, the fetal face can be rotated to the horizontal level before obtaining the eye position information to overcome the above-mentioned shortcomings.
[0051] There are many ways to correct the fetal facial image to the level. For example, to find the reference object, the line between the two eyes can be used as the reference object, and the line between the two eyes (usually the center of the two eyes) and ...
Embodiment 3
[0053] In some embodiments, in the step S102, before separately acquiring and saving the left and right face three-dimensional images displayed on the same screen by the left ear and left eye, right ear and right eye, it may also include acquiring a fetal face image The middle of the steps.
[0054] After acquiring the three-dimensional ultrasound image of the fetus’s face, if it can be ensured that the fetus’s face is in the median plane, a uniform angle can be set to control the fetal facial image to rotate to the left and right, so as to obtain the left ear and Side images of the left and right faces of the left eye, right eye and right ear.
