The system is an advanced technology applied to the diagnosis of femoral head necrosis. It was invented by Dr. Jinguo He, a postdoc of National Laboratory on Machine Perception, Peking University and by Professor Keqin Huang.

1. The technology has great practicability. The gray scale and pathologic changes presented on X-ray film, which can not be easily distinguished by the eye, can be converted into identified information or image via imaging management via computer according to the theory of vision of the human eye, color-space theory, and artificial intelligence. It can help to identify the pathologic changes earlier, and quantitatively analyze the level of lesion. So it can direct the treatment for the remodeling of hip joint and weight bearing. It is also significant for analyzing the changes of the lesion.

2.    Application

(1)  As we all know, early diagnosis of femoral head necrosis is a difficult problem all over the world. The problem can be resolved, or at least partly resolved, with this system. Early lesions than cannot be identified by X-ray or CT can be diagnosed with this system. Because of the computerized imaging, we can quantitatively evaluate the effect of therapy during the treatment period. 

(2)  This technology can accurately determine pathological changes of the femoral neck and head during the recovery of femoral neck fracture. So we can find the early lesion of femoral head and any abnormal healing of the femoral neck.

(3)   The diagnostic evidence and quantitative data can be presented for the diagnosis of delay of healing after bone fracture and early boney sclerosis.

3.  Undoubtedly, this is an advanced technology which has broad future applications. It can store thousands of X-ray images to guide scientific research and clinical studies.     

The technology of computerized color imaging diagnostic system is significant in expanding diagnostic methods and promoting the basic and clinical research of orthopedics.
