Product introduction:
The X-ray bone density and skeletal age instrument is a product that integrates the X-ray bone density measurementand bone age measurement. The X-ray skeletal age instrument uses X-rays to photograph the hand bones, and displaysthe hand bone photography images using the skeletal age analysis system software. Based on the mature characteristicsof the finger and wrist bones, the software determines the bone age of the subject, and completes the evaluation of boneage. The dual-function X-rav bone density and skeletal age instrument uses the X-ray absorption detection method toobtain high-energy and low-energy image data based on the different absorption levels of X-rays by bones and tissues otdiferent densities. The energy subtraction method is used to eliminate the influence of soft tissue on bone density measurement, The image is then analvzed and processed by software to obtain bone density measurement data while eliminat. ing the influence of soft tissue to measure bone density value of the measured site.

FAQ:
1. Why is bone age measurement important for children?
It helps assess whether a child's skeletal development is advanced or delayed compared to their chronological age.
2. Is the radiation exposure safe for children?
Yes, with an ultra-short loading time of ≤0.32s and full lead protection, the radiation dose is kept extremely low.
3. What is the imaging time for a bone density test?
The bone density scan takes 5 seconds or less, making it ideal for young, active patients.
4. Can this device be used in a pediatric clinic?
Absolutely, it is designed for minors aged 4-15 and provides essential data for growth clinics.
5. What kind of report does the skeletal age system provide?
It provides detailed skeletal maturity evaluations based on hand and wrist bone mature characteristics.
6. Does the device use cone beam scanning?
Yes, cone beam scanning is used for both bone density and skeletal age imaging for better clarity.
7. How is bone density calculated for minors?
The software provides Z-values, which compare the child's bone density to their age-matched peers.
8. What bone age algorithms are available for Chinese populations?
It includes the CHN and RUS-CHN algorithms specifically optimized for domestic clinical standards.
9. Can it monitor the impact of growth hormone therapy?
By tracking skeletal age and BMD over time, clinicians can monitor the progress of growth treatments.
10. What is the advantage of the "Energy Subtraction" method?
It effectively eliminates the influence of muscle and fat (soft tissue) to get the true bone density value.
11. Is the measurement site on the arm easy to position?
Yes, the front end of the arm (distal radius and ulna) is a standard, easy-to-access site for testing.
12. Does the device occupy a large space?
The integrated dual-function design is compact, saving valuable room in medical facilities.
13. What is the error margin for bone density?
The accuracy error is within ≤1.0%, ensuring highly reliable clinical data.
14. Is the report easy for parents to understand?
The system offers simplified report options that clearly state the evaluated bone age and density status.
15. Does the software identify phalanges and metacarpals?
Yes, the skeletal age analysis software specifically focuses on the mature characteristics of these bones.
