The authors introduce the main applications of Compton scattering-density measurement,thickness measurement and flaw detection with Compton scatter imaging and other ap.

In the field of Compton scatter imaging, the problem of how to image a large-scale object is still not fully settled.

The transmitting computed tomography and Compton back scattering tomography were used especially.

Now the existing direct volume CT methods face two difficulties:first,how to get the projection data to reconstruct the 3D image exactly,including whether the scanning structure is practical;second,how to reduce the effect of Compton scatter on reconstruction image.

Moreover, it solves many problems of the other current volume methods, such as the difficulty to implement scanning orbit for complete condition, Compton scatter to the flat panel detector based volume CT scanner, and the compli.

Compton scattering can be utilized for electron density imaging.

A Compton camera consisting of two position sensitive germanium detectors is proposed for multitracer technique.
