Bilateral-array focused ultrasound transducer with dual-frequency mode for blood-brain barrier openl-frequency mode in presence of micro-bubbles (MB). Both diameter and radius of curvature for the ultrasound transducer are 10.0cm, and the driving frequency is 10kHz difference for the left and the right elements to generate an oscillatory-amplitude focal zone. The ultrasound sonication parameters

CALIBRATION OF THE MAGNETIC TRACKER FOR ACQUISITION OF 3D IMAGES TO GUIDE NEUROSURGERIES,ily to obtain important points for the execution of Computer Assisted Neuro-Surgery using 3D Images (CANS); as well as the reconstruction of three-dimensional objects inside a Virtual Reality environment. Following the calibration, the movements acquired by the sensor are tracked by the computer in

Temperature mapping for MR-guided radiofrequency ablation - how accurate can cell necrosis be monitnecrosis..Ten patients with primary and secondary liver lesions were treated by MR-guided radiofrequency (RF) ablation. A gradient echo sequence was used to calculate temperature maps (n=22) in the plane of the RF applicators (n=10) and in a plane perpendicular to them (n=12), based on the proton re

Using microbubble contrast agent of different dosage to enhancing liver ablation induced by high-inU) ablation in goat livers in vivo. Methods: Twenty goats were divided into 4 groups randomly. Animals in group 1, 2 and 3 were bolus-injected with 0.01ml/kg/dot, 0.03ml/kg/dot and 0.05ml/kg/dot of SonoVue (Bracco SpA, Milan, Italy) intravenously respectively before HIFU exposure; and those in group

Robotic Magnetic Manoeuvring of Endoscopic Video Capsules: Phantom Tests, on ingestible capsules that allow comfortable gastrointestinal explorations. Despite their attractive capabilities, capsule endoscopes still show today a serious technical lack, which limits their clinical efficacy: their motion can not be controlled. Their movements and orientations are completely
