I-ultrasound yombala we-Four-dimensional nayo Itekhnoloji ye -4D ye-ultrasound , okwangoku yeyona teknoloji iphambili ye-ultrasound yemibala kwihlabathi. Oomatshini be -4D ultrasound basetyenziswa ngexesha lokukhulelwa kusetyenziswa iimpawu eziphambili ukubonisa imifanekiso emacala-mane kunye nentshukumo yosana olungekazalwa (ubuso be-fetal kunye namanye amalungu omzimba).
