| Abstract: | AIM: To measure low contrast resolution with statistical method. METHODS: The Catphan phantom and self- prepared experimental phantom were used to measure low contrast resolution based on the analyzing of measurement principle. RESULTS: The result of subjective method was basically consistent with that of the objective method. CONCLUSION: It is feasible to do the automatic measurement for CT low contrast resolution using self-prepared experimental phantom. |
