Risks of 3D ultrasounds
Generally, the risks of 3D ultrasounds mirror those of 2D ultrasounds, as it uses the same ultrasound waves at the same intensity. Unlike the comparison of CT scans to x-rays, 3D ultrasounds do not employ multiple snapshots of 2D ultrasounds but uses the 2D ultrasound images taken at various angles to construct an image. So the potential risk of 3D ultrasounds, if any, would depend on the duration of the ultrasound session rather than whether it is 2D or 3D.
taip kad intensyvumas identiskas 2d.
isvis koks dar 'apsvitinimas', cia ne svitinimas apskritai.
