An overview on process tomography and its applications

Process tomography(PT) has a great perspective in medical detections and industrial processes due to their non-intrusive character and visibility,and the research to PT has entered the sate of industrial applications.The operating principles of the PT that are based on optical,electrical,ultrasonic and nucleonic sensing techniques,as well as that of the multi-modality PT are introduced along with their applications in multi-phase flow measurements.
