Image fusion of MR images and real-time ultrasonography: evaluation of fusion accuracy combining two commercial instruments, a neuronavigation system and a ultrasound system

Abstract

Highly accurate fusion of MR images and real-time ultrasonography could be achieved. However, careful interpretation of the fused data is necessary, when different angles and distances of the US probe to the object are concerned.

Linear array ultrasound in low-grade glioma surgery: histology-based assessment of accuracy in comparison to conventional intraoperative ultrasound and intraoperative MRI

“…In high-grade glioma (HGG) surgery, a significant increase in EoR was shown when using a navigated cioUS device (SonoWand) [24]. Integration of ultrasound probes into a commercially available navigation system is an alternative to the above-mentioned device [18]. The navigated use of cioUS mainly facilitates orientation and interpretation of imaging findings [17].…”

Closed-Loop Control in Fused MR-TRUS Image-Guided Prostate Biopsy

“…Several systems have been presented in literature for image fusion of preoperative MRI (or CT) images and real-time US images [4] [5]. In these systems, the ultrasound probe is tracked by a localizer that assigns a global coordinate system to the US images.…”

Navigation-Supported and Sonographically-Controlled Fine-Needle Puncture in Soft Tissues of the Neck

“…Therefore, these imaging methods can only be used during navigated operations in close vicinity of bone structures serving as anatomical landmarks. For interventions in soft tissues far away from such landmarks, navigation because of soft tissue shift becomes quite inexact (Schlaier et al 2004;Unsgaard et al 2002).…”
