The common radiography work on the principle of producing images of the body parts with the help of the X-ray attenuation. This attenuation is produced because of the reaction of the components of the parts that are diagnosed. Consequently, when the emergent X-rays are analyzed they show the different attenuations for the different regions. However, it does not take in to account the effects of refraction of the X-rays in the body. In addition to this, in the radiography, the X-rays are also affected by diffraction.

For overcoming these problems, the new technology i.e. the diffraction enhanced imaging was discovered. This technology, worked on the enhancement of the diffraction of X-rays. However, later this method was improved further, to achieve the Multiple-image radiography. In this method, the images, which are free form scattering, are obtained. However, they feature both the attenuation and the refraction that the X-rays undergo.

The advantage of multiple-image radiography is that the angle of the X-rays scattering is very small. Therefore the Multiple-image radiography can show the details, which the conventional method of radiography cannot show. It produces images, which contain the microstructure of the tissues under observation. Hence it has become possible to detect the abnormalities at even finer level i.e., which were not possible with conventional radiography. In addition to this, this method has better accuracy than the conventional radiography.

A significant advantage is that the multiple-image radiography is useful for the imaging of the soft tissues as well. This was difficult to view with the conventional radiographic methods.

In addition to this as the multiple-image radiography, does not work on the absorption of the X-rays, a larger energy X-rays beam can be used for viewing the fine details of the softer tissues and even then, there is no danger of damage or harm to the patient.

For this technology, the source that is used for the generation of X-rays is generally the ‘synchrotron’. This is used as; it produces an X-ray beam having higher photon count.

The use of multiple-image radiography is that, it can show the complete scan i.e. the image involving the soft tissues as well as the harder calcified tissues. The conventional radiography cannot show the softer tissues and therefore it is not possible to know about the problems related them. Thus, only the Multiple-image radiography has made it possible to view and know about the problems in the soft tissues.
