If you want to take a photo and then find a professional bone age expert to evaluate and analyze the suggestions through the Internet, you can go to any hospital to take a photo of bone age, because any hospital, including township hospitals, may be equipped with X-ray machines, but many hospitals do not have professional doctors to understand bone age, so they often take the wrong parts, such as the measurement of knees, legs and hands. Parents will ask, don't orthopedic surgeons understand this? I really don't understand. Many parents go to see an orthopedic surgeon, and most of them take pictures of their knees. I also investigated in the provincial third-class hospitals. Because there is no pediatric endocrinology department, I find it impossible to take a standard bone age film. Physicians and orthopedic surgeons can't make a single order, because the hospital system only has an orthopedic combination package, which requires three tablets and several hundred yuan. Doctors don't know the bone age. Why don't you find a small doctor and give a standard bone age sample to the billing doctor, who can take a look at it. Basically, you can make a good bone age film, just a few tens of dollars.
