The chinese four-dimensional lottery has three main selling points:
Sex is not legal
It's not safe to leave images
Platoon malformation -- non-necessary compliance
The fetus frowned under the ultrasound, and then smiled, and when this image appeared on the orange colour screen, yao ri had red eyes, the first true knowledge of motherhood in her 29 years of life. This occurred during the five months of pregnancy at a four-dimensional photo centre in beijing。
In order to obtain this 15-minute “foetal photography”, yao li paid 1280 yuan, almost five times the ordinary ultrasound costs of public hospitals。
Yao li thinks it's worth it, after all, it's the first gift for the baby. But yao li is not aware of the health risks to the baby。
Like yao li, parents who use four-dimensional colour ultrasound devices to reach the baby are found throughout the country. The “0-year-old album” has been popular in the north for many years. Even in a private hospital in guangzhou, a four-dimensional booking has been scheduled after a month. Small-scale photography agencies have joined the battlefield. From east to east, west to kash, south to sanya and north to tsai sun, almost all cities have commercial establishments that operate a four-dimensional lottery. Beijing has even recently seen a “door service” with a portable lottery。
Businesses will tell prospective parents that tom cruz, an american movie star, bought himself a four-dimensional lottery to see his children. But they didn't say that tom cruz was already classified as a negative educational material by the united states food and drug regulatory authority (hereinafter fda)。
At the end of 2014, the fda again issued a warning that non-medical ultrasound should be banned。
“supersounding has a long safety record, but may still cause potential harm to the foetus.” the fda public relations officer, jennifer khalisky, spoke to southern weekend journalists. “we are most concerned that, under commercial models, new technologies may pose greater risks to the foetus.”
The fda view is that temporary security does not mean that there is no risk. In china, however, private hospitals and emerging foetal photography agencies completely subvert this logic. An advertisement by a private hospital stated that the fda stated that it was absolutely safe to say that there were no cases of fetal danger due to ultrasound。
“the fda's warning has been interpreted out of context and is deliberately harmful.” the chinese academy of sciences ' acoustic researcher, fengxi, was very unhappy。
On the basis of 16 million newborns per year, the potential market of up to rmb 16 billion is behind 1,000 yuan of prenatal photography. This is still a grey area where there is a lack of supervision and where sex services are illegally identified。
Four-dimensional lottery: "first dangerous gift" for the baby
Doctors can ignore the dangers
Turning the nostrils of the foetus to the spot, choosing the 4d imaging mode... The machine operated by the deputy director of the elizabeth maternity hospital, fong xiaoying, is the united states general electric (hereinafter referred to as ge) e8 series, which is a four-dimensional lottery machine worth millions。
In more than 50 years, ultrasound technology has existed, from black and white to colour, from two to three dimensions, to the emergence of the “four-dimensional” dimension of the time frame of entry ... Harisky acknowledges that technological developments have made fda, the most authoritative authority in regulating medical equipment, panic. Because of the widely known technique of “four-dimensional colouring” of the fetus, the commercial significance of “please your client” is much greater than the value of medical diagnosis。
It's like a four-dimensional thing. To be precise, four dimensions should actually be called "three dimensions in real time". In order to speed up imaging, researchers have significantly increased the number of acoustic wavelines at the head: the general 3-d colour superscope has more than 100 probes, but the e8 uses a 3d probe with 60 x 60, or 3,600 acoustic lines, 36 times the normal ultrasound。
In addition, the "four-d" colours in the ads are also "false colours". There are only two colours of medical colour: red and blue. This represents different movements of veins and arterial blood. But our familiar fetus is orange. The aim is to make the “photos” of the foetus more flexible and clear。
“the difference between colour and black and white is mistakenly assumed to be the difference between colour and black and white television, but that is far from the case.” poe feng said. The emergence of these new functions is conditional on enhanced sound output。
