PURPOSE To evaluate the clinical value of the contrast agent SonoVue in the treatment of uterine fibroids with ultrasound-guided high intensity focused ultrasound (HIFU) therapeutic ablation. MATERIALS AND METHODS A total of 291 patients with solitary uterine fibroid from three centers were treated with ultrasound-guided HIFU. Among them, 129 patients from Suining Central Hospital of Sichuan ...

Background/introduction Breast fibroadenomata (FAD) are the most common breast lesions in woman. For palpable lesions, three options are available: reassurance (with or without follow-up), vacuum assisted mammotome (VAM) or surgical excision. High intensity focused ultrasound (HIFU) is a non-invasive ablative technique in which an ultrasound (US) beam propagates through tissue as a high-frequen...

High Intensity Focused Ultrasound (HIFU) allows non invasive treatment of uterine fibroids without anaesthesia and a fast return to normal activity [1]. For this thermotherapy procedure, MR guidance provides anatomical images to plan treatment of the fibroid, thermal maps to quantify the HIFU heating and contrast enhanced images to measure the induced nonperfused volume. This routine clinical p...

A new approach for characterizing high intensity focused ultrasound (HIFU) transducers is presented. The technique is based upon the acoustic streaming field generated by absorption of the HIFU beam in a liquid medium. The streaming field is quantified using digital particle image velocimetry, and a numerical algorithm is employed to compute the acoustic intensity field giving rise to the obser...

The effect of error feedback on the accuracy of output task types such as editing task, text reconstruction task, picture cued writing task, and dictogloss task, has not been clearly explored. Following arguments concerning that the combination of both corrective feedback and output makes it difficult to determine whether their effects were in combination or alone, the purpose of the present st...

In this paper, we present a new approach for building and archiving web collections about events. Our approach combines the traditional focused crawling technique with event modeling and representation.

Abstract The extent to which teachers’ written corrective feedback (WCF) is conducive to ESL learners’ improvement has been discussed since Truscott’s claim in 1996. The mentioned debate continues because there has been lots of contrastive research studies with different results. This paper presents the results of a 2-month study of the effectiveness of WCF to 65 low intermediate Iranian learne...

In this paper we describe our participation in INEX 2009 in the Ad Hoc Track, the Book Track, and the Entity Ranking Track. In the Ad Hoc track we investigate focused link evidence, using only links from retrieved sections. The new collection is not only annotated with Wikipedia categories, but also with YAGO/WordNet categories. We explore how we can use both types of category information, in t...

During application of high intensity focused ultrasound (HIFU) with therapy arrays, the existence of grating lobes can cause heating at unintended tissue regions. Therefore, the reduction of grating lobes in therapeutic arrays is an important goal. One way to reduce the grating lobes in therapy arrays is to excite the arrays with broadband signals (defined here as >10% fractional bandwidth). To...
