Outline of Final Research Achievements |
A broadband sector ultrasound probe with 64 elements was developed and ultrasound was emitted and received by a programmable ultrasound RF signal processor. Two-dimensional blood flow velocity was deduced by measuring the blood flow vectors from two different viewpoints. The algorithm was validated by a mock blood flow model. Two-dimensional blood flow information on parallel planes were input in three-dimensional equation of continuity and an algorithm for three-dimensional blood flow measurement was developed.
