Title:
チャープ反転超音波コントラスト撮像
Document Type and Number:
Japanese Patent JP2008543475
Kind Code:
A
Abstract:
The invention relates to a method for detecting and imaging ultrasound echo signals returned from a target object comprising microbubbles, said microbubbles being characterized by a resonance frequency, said method comprising the steps of irradiating said target object with at least a first and second successive excitation signals, said first excitation signal being a sweep of increasing frequency with time, and said second excitation signal being a sweep of decreasing frequency with time, detecting echo signals of said first and second excitation signals from said target object, and, combining said echo signals. The maximum frequencies of said first and second excitation signals are lower than said resonance frequency. The invention also relates to an imaging apparatus.
