Backward-mode ultrafast pulsed magnetomotive ultrasound

摘要

Recently, magnetomotive ultrasound (MMUS), which is capable of ultrasonic visualization of in vivo magnetic nanoparticle distribution challenging to conventional B-mode ultrasound, has shown its potential in extravascular ultrasound molecular imaging, magnetic nano-drug delivery monitoring, and sentinel lymph node identification. However, to date, only forward-mode MMUS where the imaging object is placed in between an ultrasound probe and an electromagnet is implemented in the literature. Such a MMUS mode is not suitable for clinical use.
