"Perhaps... I may really bring a future new member to the Gigabyte Society by coming here this time?"

While thinking in this way, Tao Zhexuan asked the entourage who were carrying large boxes and small bags to come forward and show the contents in front of everyone.

In fact, until this time, Tao Zhexuan was dubious about the IQ value of Tangtang's previous test.

This is a common problem of human beings, seeing is believing!

Especially Tao Zhexuan, a genius with high IQ, believes in his own personal test.

After all, as a mathematician, critical thinking is already in the brain.

"These are the instruments used to test Xiaotangtang's bone age!"

"In response to doubts from the outside world, and to make the test more accurate, this test must be done!"

Watching Fang Yu and Tang Qian beside him, after seeing the various instruments they took out, the doubts that appeared in their eyes, Tao Zhexuan explained.

bone age!

Bone age is short for skeletal age.

The degree of human growth and development can be expressed by two ages, namely life age (calendar age) and biological age (bone age).

The changes in the development of human bones are basically similar, and the development process of each bone has continuity and stages, while bones at different stages have different morphological characteristics

Therefore, bone age assessment can more accurately reflect the growth and development level and maturity of the individual.

It can not only determine the biological age of children, but also can understand the growth and development potential of children and the trend of sexual maturity early through bone age.

Bone age can also predict children's adult height, and the determination of bone age is also very helpful for the diagnosis of some pediatric endocrine diseases.

The detection of bone age can be determined by means of specific images of bones in X-ray imaging.

In traditional bone age assessment, X-rays are usually taken of the hands and wrists of the subject, and then interpreted by doctors based on the X-rays taken.

The disadvantage is that there is radiation, the result is greatly affected by the doctor's subjective, and the time is long.

Israel has developed a new technique called BonAge for ultrasound bone age assessment. The instrument brought by Terence Tao this time to test the bone age of Xiaotangtang is the result of this technology.

The methods for determining bone age include simple counting method, atlas method, scoring method and computer bone age scoring method.

The most commonly used are the G-P atlas method and the TW2, TW3 scoring methods, among which the G-P atlas method of the wrist bone development atlas is widely spread.

The G-P map is based on the results of a longitudinal study from birth to adulthood of children from upper-middle-class families in the United States.

Atlas method is mainly based on the sequence of appearance and disappearance of wrist ossification centers and metaphyses at different ages in children and adolescents to establish a standard atlas of bone age for men and women. During the evaluation, the X-rays to be tested are compared with the atlases one by one, and the most similar one is taken as the bone age. Between two adjacent age maps, the average value is used to estimate.

However, the atlas method is highly subjective, has large deviations, and the rate of bone maturation is not clear.

Therefore, scientists proposed the TW1 bone age scoring method in 1962 through research, and revised it to the TW2 method in 1979.

In this method, 20 wrist bones were taken from the left wrist front view, and each bone was divided into 8-9 stages according to different developmental grades, and different scores were assigned. The total bone development score ranged from 0-1000 points.

Accumulate the bone development points from the wrist x-ray, and then check the bone age score table or SMS-age curve to obtain the bone age.

However, due to the particularity of Xiaotangtang, Tao Zhexuan or Gigabyte Society this time, abandoned these two methods with various defects.

With the help of modern technology, computer-assisted bone age assessment, ultrasound bone age, and dual-energy X-ray absorptiometry (DXA), that is, bone densitometer, are used to evaluate the accurate bone age of Xiaotangtang.

Use the current top-notch and most accurate methods to minimize the error.

While Tao Zhexuan was assembling the entourage, he also introduced to Fang Yu and Tang Qian the specific (bjai) functions of each instrument.

This also let Fang Yu and Tang Qian know what the weird machine that was quickly assembled in front of them was.

"It won't hurt Tangtang, will it?"

As a mother, Tang Qian was a little worried when she saw the instrument in front of her.

Tao Zhexuan was single-minded, seeing Tang Qian's worry, while adjusting the instrument, he explained to Tang Qian:

"Mrs. Fang, please rest assured!"

"The equipment we brought this time will not cause any harm to Xiaotangtang!"

As for Fang Yu.

Knowing that Xiao Tangtang has a physique as high as 37, a small check will not have any impact on Xiao Tangtang at all.

Moreover, Fang Yu believed that people like Tao Zhexuan would not and would not bother to use despicable methods against a baby.

I also believe that there are officials who belong to Huaxia, and Chen Wenjin, the chairman Sheng Han who tried his best to invite Xiao Tangtang to join the association, will not let something unfavorable to Tangtang happen.

Since he chose Gigabit, Fang Yu handed over all the testing process to them.

"Then trouble Professor Tao!"

After Fang Yu spoke, Tao Zhexuan began the formal test.

Before starting, Tao Zhexuan took out a document from his purse.

This is the special recording paper used by Gigabyte for the dispersion IQ test.

"Okay, Xiaotangtang, the next month will be a simple question-and-answer game..."

After speaking, Tao Zhexuan looked at Fang Yu, and asked softly: "Mr. Fang, I want to ask how old Tangtang is now? To be more specific, it should be accurate to the sky."

Fang Yu, who has gone through the last test, naturally knows that Tangtang has written down his age.

"43!"

Tangtang answered bluntly first, with a pure and flawless smile on his face.

Before, Tangtang heard Tang Qian and Fang Yu mention about her age, Tangtang remembered it.

At the same time, Fang Yu nodded approvingly. Knowing that Tangtang has improved a lot now compared to the first test ten days ago!

Already able to understand questions and answers, although only some simple dialogues.

And it seems that Tangtang really clearly remembers her every day!

"Really 43 days?"

Tao Zhexuan couldn't hide the shock on his face.

This kid not only understood his question...but actually gave the correct answer?

But Terence Tao seldom sees Fang Yu like this, only a fleeting surprise.

With Tao Zhexuan's IQ, even Fang Yu's enthusiasm immediately after that, the calmness under that enthusiasm. Nor did it escape Tao Zhexuan's eyes.

At this moment, Tao Zhexuan somewhat believed the news that Xiaotangtang's IQ had reached 826.

Even the worst results are not achieved.

Tao Zhexuan also believes that Xiaotangtang's IQ will not be low. .
