Na ho na le C-ultrasounds le D-ultrasounds?
Ha ho na C-ultrasounds, empa ho na le D-ultrasounds.D ultrasound kedoppler ultrasound, ke kopo eadoppler molao-motheo oa ultrasound.Rea tseba hore molumo o na ledoppler effect, e leng ha terene e feta ka pel'a hao, molumo o tsamaea ka potlako ebe o lieha.Ho sebelisadmolao-motheo oa oppler, a ka u tsebisa hore na ho na le ntho e tsamaeang ho uena kapa hole le uena.Ka mohlala, ha u sebelisa ultrasound ho lekanya phallo ea mali, ho ka sebelisoa mebala e ’meli ho tšoaea phallo ea mali, ’me botebo ba ’mala bo sebelisetsoa ho bontša phallo ea mali.Sena se bitsoa color ultrasound.
