Doppler ultrasound imaging of magnetically vibrated brachytherapy seeds.
Vibration induced by an alternating magnetic field is proposed as a method for the identification of modified brachytherapy seeds with Doppler ultrasound. In vitro experiments with agar and liver-tissue phantoms using a clinical scanner and simple apparatus demonstrate that the technique is feasible.
