If the distance from the end of the longitudinal diameter to the point where the ultrasonic probe is located (D) or the point at which the ultrasound is emitted (D) is called depth, the distance between point D and C, that is, b is the depth at Depth. It is minus OFD / 2, and the distance between point B and C, that is, d is BPD / 2.

By setting the triangle BCD connecting points B, C, and D, ∠BDC can be seen as half of the scan angle needed to include information about the fetus in a three-dimensional ultrasound image. Multiplying it yields an appropriate scan angle.

Therefore, the calculation of the appropriate scan angle when the fetus is three-dimensional scan can be summarized by Equation 1 below.

[Equation 1]

A = 2 x tan -1 (d / b)

b = Depth-(OFD / 2)

d = BPD / 2
