Introduction In aliased images, pixels from different parts of the field of view overlap. The task of parallel imaging reconstruction is equivalent to extracting each individual pixel from the sum. Magnetic resonance spectroscopy (MRS) has long sought to extract a signal of interest from overlapping signals at the same frequency using various spectral editing techniques. One very effective spec...

PURPOSE Over the past decade, a number of arthroscopic or arthroscopically assisted reconstruction techniques have emerged for the management of acromioclavicular (AC) separations. These techniques provide the advantage of superior visualization of the base of the coracoid, less soft tissue dissection, and smaller incisions. While these techniques have been reported to provide excellent functio...

OBJECTIVES/HYPOTHESIS To assess the medium-term efficacy of total ossicular reconstruction with a titanium total ossicular replacement prosthesis (TORP) in children. STUDY DESIGN Case series. METHODS A consecutive series of children receiving an adjustable-length titanium TORP was identified from a prospective surgical and audiological database. Audiometric testing was obtained preoperative...

UNLABELLED The goal of this study was to assess the effect of diaphragmatic respiratory motion on inferior wall cold artifact in myocardial SPECT and to assess the ability of attenuation correction (AC) to correct for this artifact in the presence of diaphragmatic motion. METHODS We used an anthropomorphic phantom with ventricular wall activity, variable ventricular caudal tilt, attenuating l...

Most of the ac-ac converters used in home-appliances are based on single-output dc-link inverters, which provides a cost-effective and straight-forward solution. However, this twostage power conversion decreases power density and efficiency. Direct ac-ac conversion has been thoroughly studied in the past. However, the complex control scheme and higher cost has prevented it from being used in lo...

Articular cartilage (AC) is a seemingly simple tissue that has only one type of constituting cell and no blood vessels and nerves. In the early days of tissue engineering, cartilage appeared to be an easy and promising target for reconstruction and this was especially motivating because of widespread AC pathologies such as osteoarthritis and frequent sports-induced injuries. However, AC has pro...

AC induction motors become very popular for motion control applications due to their simple and reliable construction. Control of drives based on AC induction motors is a quite complex task. Provided the vector control algorithm is used we need to know not only the rotor speed but also the position of the magnetic flux inside the motor during the control process. In most applications the magnet...

Various local probes have been applied to understanding current flow through superconducting films, which are often surprisingly inhomogeneous. Here, we show that magnetic imaging allows quantitative reconstruction of both current density J and electric field E resolved in time and space in a film carrying subcritical ac current. Current reconstruction entails inversion of the Biot-Savart law, ...

Abstract Introduction Rupture of the anterior cruciate ligament (ACL) is one frequent traumatic injuries knee joint complex, and isokinetic dynamometer essential to assess measure its function. Objective To analyze volume physical therapy treatment using same protocol with different duration in patients undergoing ACL reconstruction. Methods This a prospective observational cohort study. The sa...

This prospective study reports the results of early failure of coracoclavicular (CC) ligament reconstruction using TightRope. Nine consecutive patients who had CC ligament reconstruction using TightRope or GraftRope were assessed for radiological and functional outcomes using DASH and Oxford Shoulder scores. With an average age of 38.4 (21-70) years, four patients had type III injuries, two typ...
