Ultrasonography is a widespread intraoperative imaging modality. However, it suffers from several shortcomings e.g. its dependance on the skills of the operator for the image quality. To overcome this shortcoming, Gumprecht et al. [1] recently proposed a new robot-assisted flat-panel ultrasound device for continuous intraoperative imaging during laparoscopic tumor resection in urology. This device...
Three-dimensional ultrasound has been an effective imaging modality for diagnostics and is now an emerging modality for image-guided minimally-invasive interventions since it enables visualization of both instruments and tissue. Challenges to ultrasound-guided interventions arise, however, due to the low signal-to-noise ratio and the imaging artifacts created by the interventional instruments. Metallic...
