Have you ever had a 4d ultrasound while pregnant?

I had the 3d ones. This was only during my first pregnancy, apparently that was the only ultrasound machine they had so all my ultrasounds were done in 3d.

We can’t comprehend the fourth dimention. It’s 3D

My girl friend had one today and called it 4d…maybe I’m wrong though.

@XOIIO I think they try saying 4D is adding sound, but I don’t see how that makes sense.

I’ve seen it being called 4D in a lot of areas. They are marketing it that way, but it makes no sense. Either way it’s making money because it’s “technologically” advanced.

@XOIIO I doubled checked. It’s being called 4d. Either way, that’s not the point. 3d, 4d, whatever.

I haven’t had any 4D ultrasounds, but I have had 3D ones because the specialist I was seeing when we were concerned about a possible heart defect did them. I honestly think the 3D/4D pictures look creepy. Basically, a 4D ultrasound is 3D pictures with more angles and can show more real time movement of the baby than the traditional ultrasound machines.

If your doctor doesn’t do them, there are usually ultrasound places that do them as well. You may just have to do a google search to see if there are any in your area. If you do that, you will have to pay for it yourself since they aren’t seen as medically necessary. How much they cost will depend on where you go to get them.

@Ajulutsikael That’s totally false marketing, or some uneducated person doesn’t know what they are talking about.

A friend of mine had a few 4D ultrasounds because she is high risk and is having twins. I saw the pics and they look amazing! You can see the babies almost as if a black and white picture. Ask your doctor to refer you, but you may have to pay for it yourself, your insurance may not cover it.

(it is called 3d and 4d ultrasound..)
I had one with both pregnancies. Wait until at least 29 weeks so the baby is chubby enough. With my second it was done at I believe 31 weeks.
I loved it. You really get to see what the little one will look like, which I love. My second boy was SO chubby and he’s still super chubby haha. My first looked a lot like my brother and sure enough he popped out looking like me and my brother. It was well worth the memories!

Oh and it is not a doctor visit. You do have to prove you are getting ob/gyn care, but just google your area and 3d/4d ultrasounds…businesses will show up. And go with the one with the best prices IMO.

Wiki says that the fourth D means that the ultrasound is happening in real time instead of offering a delayed image.

@casheroo I found a place right down the road from me. It looks very nice! And it’s about $140 for the package I want. Totally worth it :)

no i havnt heard it but hav heard about a 3d ultrasounds
here you can view 4d too

A typical ultrasound is a flat planar section in time so 2D+1D.
Fancy new techniques allow calculation and representation of depth in real time 3D + 1D

The availability of computing power has defined the features of ultrasound scanners since their inception.
@XOIIO, it’s actually a fair label as time is considerred one of the “D“s.
@Nullo, Crazy ole Wiki. “real time instead of offering a delayed image” That was true In the 70’s when ultrasound was just getting off the ground, you got a 2D image a while after the picture was ‘snapped’ as it took some time for the computing hardware at that time to assemble the image from collected data.
But that hasn’t been the case for a long time. Available affordable computers are orders of magnitude more powerful these days. For a couple decades ultrasounds have been full-motion 2D, in realtime (“3D”). (Plus sound, for echocardiograms you can hear the bloodflow in the part of the heart being scanned – fantastic! If you have a murmur or regurgitation you can hear that and see the cause. The sound isn’t from a microphone either, it’s reconstructed from doppler information in the waves bouncing back from the portion of the heart being scanned.)

In the newest fancier ultrasound systems, the computing resources are powerful enough to provide a representation of depth, 3D, in realtime, so spatial depth is the new 4th D added recently.

Back in the 70’s I worked as a electronics repair guy on peripherals to ultrasound machines and saw the nascent technolgy being used mostly for pre-natal at that time. Computing power was very expensive as each manufacturer built their own processors out of discrete logic. The imaging process borrowed a lot from the maths and methods used for phased array radar systems. Jaw-dropping engineering to my mind.
Only coincidentally, recently someone near and dear became a cardiac ultrasound tech and I had fun following the training and continue to pick up some of the trade rags out of curiosity to see what’s new. (Being a handy guinea pig, I’ve been practice-scanned according to all the common non-invasive cardiac and vascular ultrasound protocals.)

Computing power is now so cheap, compact and powerful (hey! youtube on my phone!) GE has a 3D unit (2D in realtime) that fits in your hand.
