英國最快樂寶寶：打娘胎起就“笑口常開”

Grinning from ear to ear, this picture shows little Leo Hargreaves was rather happy with his world – even before he was born.

And his parents believe their son may be the happiest baby in Britain as he hasn’t stopped smiling since.

The remarkable image was taken from an ultrasound scan at 31 weeks.

His mother Amy Cregg, 24, said: 'My partner Leighton and I were absolutely shocked - even the people who did my scan were amazed.

'But that was just the beginning. After he was born, he was always smiling - even in his sleep.'

Now nearly five months old, Leo has been dubbed the happiest baby in Britain.

The image is a 4D scan - increasingly popular with expectant parents to get a glimpse of how their child will look.

Rather then the grainy ‘flat’ images produced by the 2D scanners usually used by the NHS, a 4D machine stitches together pictures taken from a variety of angles to create clear three-dimensional images.

These are then recorded on video – the fourth dimension.

Ms Clegg, from Accrington, Lancashire, said she has already had modelling companies approach her trying to capture Leo’s smile.

The rehabilitation support worker said: 'I’ve been walking in the park and had people come up to me and say "What a gorgeous baby".

'I’d be interested in him doing modelling but only when he’s older.'

A spokesman for the company that performed the scan, at Babybond Ultrasound Direct in Burnley, said: 'Our sonographer who scanned Amy and her gorgeous baby was overwhelmed at her smiley baby throughout the entire scan.'

4D scans are a highly developed form of traditional ultrasound where very high frequency sound waves are used to produce images of what is inside the body.

As with older forms of ultra-sound, sound waves a emitted from a transducer, or probe, which is placed on the mother's abdomen and then moved to 'look at' areas in the uterus.

These sound waves bounce back off the foetus, helping to create a 'picture' of the child on a screen.

4D scans use the same frequency of sound waves as in a normal ultrasound.

But the sound waves are directed from many more angles, producing a 'real-time' video of the foetus as it moves and allowing scientists to say the images are in four dimensions.照片上這位名叫里奧?哈格里夫斯(Leo Hargreaves)的小寶貝還未出生就已經(jīng)咧著嘴笑個不停，一臉幸福的樣子。

里奧的父母相信他們的兒子是全英國最快樂的寶寶，因為他的笑容從未消失。

這張與眾不同的照片來自于超聲波掃描，當(dāng)時里奧才31周大。

里奧的母親艾美?克萊格(Amy Cregg)今年24歲，她說：“我和我的愛人萊頓(Leighton)大感驚奇，甚至那些給我做掃描的人們也驚嘆不已。不過那只是個開端。他出生之后也一直在笑，甚至在睡夢中。”

現(xiàn)在的里奧快有五個月大了，他已經(jīng)被冠上全英國最快樂小寶寶的稱號。

圖像由4D掃描采集。這項技術(shù)越來越受準(zhǔn)爸爸準(zhǔn)媽媽的歡迎，他們迫不及待地想要一窺自家孩子的模樣。

英國國民保健服務(wù)(NHS)通常使用2D掃描，由此拍出的圖像是平面點狀物，而4D掃描則將多角度拍攝而成的圖片拼接在一起組成清晰的三維圖像。

這第四個維度就是寶寶在母親肚子里的一舉一動被記錄成像。

母親克萊格女士來自蘭開夏郡(Lancashire)，是一位康復(fù)治療師。她說她已經(jīng)接到幾家模特公司的邀請，希望能拍攝寶寶的笑容。

“我在公園里散步就會有人走過來說‘多可愛的寶寶啊’。”

“我對他做模特拍片的事很有興趣，不過只有等他再大點兒才行。”

位于伯恩利一家名為Babybond的超聲波醫(yī)療公司為里奧拍攝了4D掃描圖像。該公司的新聞發(fā)言人稱當(dāng)時給母子兩進行超聲波檢查的醫(yī)生在看見完整的圖像后也被寶寶的笑容征服了。

傳統(tǒng)超聲波技術(shù)利用超頻聲波成像來顯示人體內(nèi)的情況，而4D掃描則在此基礎(chǔ)之上進一步發(fā)展，技術(shù)更為成熟。

不過和舊有超聲波傳遞方式一樣，聲波通過母親小腹上的傳感器或者探測器進入人體，同時借助它們的移動來“瞧”子宮的內(nèi)部情況。

這些聲波在遇到胎兒時會被彈回，胎兒的“照片”也就能顯示在屏幕上了。

4D掃描的聲波頻率和普通超聲波技術(shù)使用的相同。

只是4D的聲波能多角度幫助紀錄胎兒在母體內(nèi)的活動并形成一部“實時”動畫?？茖W(xué)家們也有理由稱其為四維成像。
