Abstract :
A large, one dimensional receiving array has been developed in the attenuation projection measurement and the phase insensitive (PIS) data processing method has been used in the evaluation. Our aim of this study is to suppress the corresponding artifacts in the attenuation projection. Four different cylindrical, biomaterial objects are tested in the measurement. The results are compared with phase sensitive (PS) results. The conclusion is given in the last part.
