متن کاملIntroducing a bony composite as tissue equivalent for radiotherapy phantoms
The use of a device that simulates the actual condition, as well as being equivalent to the human body in materials and tissues, and having the capability of acting like internal motions of human body is necessary to investigate and simulate the motion of a tumor in radiotherapy and to evaluate dosimetrical coverage of the dynamic target. This device which is called the dynamic phantom should s...
