What is a 2D Ultrasound?
The 2D (or two-dimensional) black and white ultrasound image is what most people recognize from their regular medical ultrasounds.
The ultrasound image is created when sound waves emitted from a special hand-held device are transmitted into the body and reflected with varying intensity. The strength of these reflected signals or echoes are processed and displayed as varying shades of grey giving us our resulting 2D black and white image.
At Baby in Sight we regularly utilize 2D imaging when doing a 4D ultrasound. You will often observe during your 4D session, the sonographer selecting the 2D mode initially to correctly place a volume box over an area of interest prior to launching into the 4D/volume mode.
Two-dimensional ultrasound is often the preferred mode when determining gender for smaller babies. While we still utilize both 2D and 4D imaging for all gender determination sessions, the baby’s position can sometimes make it more difficult for ultrasound technologists to visualize the genitalia in 4D for these younger babies. Consequently, you may notice the technologist has a preference for the more conventional 2D ultrasound imaging when doing early gender scans. Gender determination for the more advanced pregnancy is usually easily accomplished in both 2D and 4D modes.
We occasionally get requests to do entire sessions in 2D. We understand that not everyone wants to discover who their baby looks like until the magical day so just let us know your preference and we are happy to accommodate you. As with our 4D sessions, 2D black and white images can be preserved digitally as video or jpeg images and we can also provide you with high resolution, hard copy prints.
If you have any questions please don’t hesitate to contact us.
