CIRCULAR TOMOSYNTHESIS FOR X-RAY RADIOGRAPHS OF TISSUES (2) SIMULATION OF OPTIMAL TOMOSYNTHESIS SLICE
|
Abstract:
In 3-dimensional reconstruction of tomosynthesis, we have proposed two kinds of scanning sample methods for X-ray radiographs. One is single-cone sampling tomosynthesis which corresponds to the zero order Bessel window function. Other is the prolate window function for a triple-cone sampling tomosynthesis. With the proper choice of the windnw parameters, the sampling geometry was designed and the attenuations of the different window functions were simulated.
