Embodiment 1
[0038] This embodiment provides a three-dimensional ultrasonic imaging device, its structural block diagram is as follows figure 1 shown. The three-dimensional ultrasonic imaging device includes a probe 102 , a transmit / receive selection switch 103 , a transmit circuit 104 , a receive circuit 105 , a beam forming module 106 , a signal processing module 107 , a three-dimensional imaging module 108 and a display 109 . The transmitting circuit 104 sends a group of pulses with delayed focus to the probe 102, and the probe 102 transmits ultrasonic waves to the body tissue under test (not shown in the figure), and receives the tissue-bearing tissue reflected from the body tissue under test after a certain delay. The ultrasonic echo of the information is converted back into an electrical signal. The receiving circuit 105 receives the ultrasonic echo signals converted into electrical signals, and sends the ultrasonic echo signals to the beamforming module 106 . The ultrasonic echo s...
Embodiment 2
[0069] The three-dimensional ultrasound imaging method / system provided in this embodiment is similar to Embodiment 1, and the same parts of the two will not be repeated here. The difference is that in step 25 of Embodiment 1, the fetus in the mid-sagittal section is determined by the orientation of the skull. and the step 25 of this embodiment is to determine the head orientation of the fetus in the midsagittal section according to the orientation of the transparent compartment.
[0070] Such as Figure 5 and Figure 8 As shown, in the ultrasound image, the shape of the transparent septum is a curved crescent. When the fetus is upright in the ultrasound image, the transparent septum appears as an upward crescent shape. On the contrary, when the fetus is inverted in the ultrasound image , the hyaline compartment exhibits a downwardly convex crescent shape. Therefore, the orientation of the fetal head on the midsagittal plane can be judged according to the orientation of the l...
Embodiment 3
[0080] The three-dimensional ultrasonic imaging method provided in this embodiment is as follows: Figure 12 As shown, it includes: step 21 of obtaining the three-dimensional volume data of the fetal head, step 23 of detecting the midsagittal section, step 27 of judging the face orientation, and step 29 of displaying the midsagittal section. Wherein, steps 21, 23 and 29 are the same as those in embodiment 1 or 2, and will not be repeated here. Based on the method, this embodiment also provides a three-dimensional ultrasonic imaging device for implementing the method. For the structure of the device except for the three-dimensional ultrasonic imaging part, reference may be made to the foregoing embodiment 1, which will not be repeated here.
[0081] Because the transparent compartment is located at the front of the cranium, the face and back of the fetus (that is, the face orientation of the fetus) can be determined through the position of the transparent compartment.
