三维超声图像引导肉毒素注射系统

Patients with stroke or brain damage suffer from some degree of muscular spasm. Inadequate healing may slow down the rehabilitation. Botulinum toxin injection has been applied widely for muscular spasm treatment. The localization of spasm muscle is the key to efficient treatment.This paper presents a novel three dimensional ultrasound image guided botulinum toxin injection system. The system employed a common two dimensional ultrasound scanner to build a three dimensional ultrasound imaging system. Based on muscle visualization and optical positioning, a injector is guided into the target muscle. Experiments verified the accuracy and validation. The experiment results suggest that the proposed system could guided the injector into the target muscle for botulinum toxin injection.
