There are three respects of the functions:boundary function,statue function and record function.

Technology of Functional Imaging Based on Photons Diffuse

There are many kinds of functional imaging technologies used in the medical field with their different advantages and disadvantages and clinical applications,which should be mastered fully in order to offer better clinical services by applying such resources reasonably.

Electrical impedance tomography is a new generation of functional imaging developed in recent ten or more years after the morphology and structure imaging technology.

Functional imaging of liver using ultrasound contrast agents:state of the art;

Application and prospect of functional imaging on defining biological target volume in non-small cell lung cancer;

With the development of image technology,functional imaging was gradually applied to contouring the gross target volume,which generated the concept of biological target volume and biological intensity-modulated radiation therapy.
