The effectiveness of magnetic resonance imaging (MRI) to monitor thermal lesions created by High Intensity Focused Ultrasound (HIFU) in rabbit liver in vivo is investigated. The MRI sequences of T1-weighted, and T2-weighted fast spin echo (FSE) were evaluated. The main goal in this paper was to find the range of repetition time (TR) and range of echo time(More)
BACKGROUND A prototype magnetic resonance image (MRI)-conditional robot was developed for navigating a high-intensity focused ultrasound (HIFU) system in order to treat prostate cancer transrectally. MATERIALS AND METHODS The developed robotic device utilizes three PC-controlled axes: a linear axis for motion along the rectum, an angular axis for rotation(More)

We read with great interest the article recently published in the European Respiratory Journal (ERJ) by RIOS et al. [1] regarding ventilator-associated pneumonia (VAP) due to colistin susceptible-only microorganisms. The authors concluded that colistin could be a suitable antibiotic for the initial empiric antimicrobial therapy in their intensive care unit(More)
In this paper magnetic resonance imaging (MRI) is investigated for monitoring the penetration of high intensity focused ultrasound (HIFU) ex vivo and in vivo rabbit brain. A single element spherically focused transducer of 5 cm diameter, focusing at 10 cm and operating at 2 MHz was used. A prototype MRI- compatible positioning device is described. MRI(More)
