Analysis on development and application value of new method of fluorosis of bone X-ray photography

  Objective   To decide the method of fluor osis of bone x-ray photography and study the value in making diagnosis.

  Methods   55 patients of fluorosis of bone were selected and 30°, 45°, 60° boards were made according to the extent of function barrier of the patients.The part photogr aphed were fixed and antebrachiums and legs properly intorted or outward rotated in order to prevent the photos from overlapping.The KV capacity were raised or reduced in order to make the bone photos clear to the work of basin exposure.Contrast groups were established in order to observe the effect of photos and diagnosis.

  Results   The quality of the photos were better than the ones before improvement and the border of the fusion bo ne construction were clear.It was completely showed that the bony trabecula turned loose, obscure and cortex of bone turned thin, so the rate of accuracy was improved.

  Conclusion   The new method of fluorosis of bone x-ray photography were flexible, simple and practical and it gave reliable security for x-ray diagnosis.
