ULTRASONOGRAPH

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonograph for obtaining an image of higher image quality while avoiding an increase in factor holding memories. SOLUTION: This ultrasonograph has a dynamic filter including FIR filters 1 and 4 connected in series by two or more, and controls so as to become different in the factor switching timing of the respective filters 1 and 4. The factor holding memories 2 and 5 can be effectively used by switching factors of the respective filters 1 and 4 in the proper timing.
