BACKGROUND/AIMS To evaluate the safety and efficacy of high intensity focused ultrasound (HIFU) therapy in patients with local advanced pancreatic cancer. METHODOLOGY 39 patients with local advanced pancreatic cancer were treated with HIFU, including 26 male and 13 female patients. The locations of the tumours were as follows: head of pancreas in 7 patients, body and/or tail of pancreas in 32...

High intensity focused ultrasound (HIFU) is a minimally invasive treatment option that might be considered in the management of localized prostate cancer. It is a well-tolerated treatment with few minor urologic complications and no major toxicities. In this paper, we report to our knowledge the first case of levator ani necrosis in a patient treated with HIFU, manifesting as sturdy perineal pa...

Background/introduction Background: In the absence of randomised study data institutional series have shown High Intensity Focused Ultrasound (HIFU) to produce excellent overall and cancer specific survival rates in patients with localized prostate cancer (LPCa) compared with alternative curative treatments. Objectives: To evaluate the oncologic outcome of patients treated with HIFU versus conf...

Plenoptic cameras, constructed with internal microlens arrays, capture both spatial and angular information, i.e., the full four-dimensional radiance, of a scene. The design of traditional plenoptic cameras assumes that each microlens image is completely defocused with respect to the image created by the main camera lens. As a result, only a single pixel in the final image is rendered from each...

Abstract This study was an attempt to investigate the effect of collaborative form-focused activities on grammar learning of elementary EFL learners. To this end, 58 adult male Iranian EFL learners at elementary level of proficiency in three classes of language institutes were chosen. They formed the three groups of the study. The grammar section of Cambridge Michigan Placement test was used to...

This paper reviews the literature regarding the use of acoustic droplet vaporization (ADV) in clinical applications of imaging, embolic therapy, and therapeutic delivery. ADV is a physical process in which the pressure waves of ultrasound induce a phase transition that causes superheated liquid nanodroplets to form gas bubbles. The bubbles provide ultrasonic imaging contrast and other functions...
