Innovative solution for hearing loss

Otologics' Carina could improve the quality of life for patients suffering from hearing loss. The fully implantable hearing device uses a transducer to move the middle ear bones - much like the eardrum causes the middle ear bones to vibrate in response to sound wave. Carina implantation surgery takes about three hours and is an easy procedure with low surgical risks. (The whole article is only…

Cardiac MSCT Study Assessment with Sure Plaque-Software

Ongoing refinement of modern helical multi-slice CT (MSCT) scanners offers the opportunity for very high temporal and spatial resolution thin-slice data set acquisition. The reconstruction techniques offered (multisegment reconstruction) result in improved temporal resolution down to 40-200 ms and thus also reducing motion artifacts. The SURECardio software package makes possible optimum studies…

Selenium-Based Flat Panel X-ray Detector for Digital Fluoroscopy and Radiography

We have succeeded in developing the first selenium-based flat panel X-ray detector for digital fluoroscopy and radiography. This flat panel X-ray detector efficiently captures X-rays that have passed through the patient's body and converts them directly to digital dynamic and static images. It has been confirmed that images with high spatial resolution and contrast can be obtained. The detector…

Clinical Experience with a Superconducting MRI Scanner

Following the installation of a 0.5-T superconducting magnetic resonance imaging (MRI) system at our hospital in 1987, we have been performing a large number of examinations as a key regional hospital serving the city of Muroran, Hokkaido, and surrounding areas. However, compared with more recently developed MRI systems, 0.5-T systems tend to have poorer image quality and a restricted range of…

Technical Insights into the Dual-slice CT

In 1999, the Aquillion/MULTI and Asteion/MULTI multi-slice systems with highly integrated 34-channel detector system, both consisting of a total of 30,464 detector elements, were introduced. On the basis of such a structured detector matrix, a new image reconstruction procedure was used. This so called MUSCOT (Multislice Conebeam Tomography) procedure made the dream of an isotropic voxel in the…

Magic Microbubbles

The introduction of a new generation of microbubbles has created opportunities for ultrasound, and this is particularly true in the liver, where study of the arterial, venous and sinusoidal phases with an agent such as SonoVue at low ultrasound power levels (Iow mechanical index, MI) provides unique information. Similar diagnostic advantages can be obtained in diseases of the kidneys, spleen and…

The Four Pillars of Successful Digital Networking

During the past several years, the term DICOM has become a phrase in the digital world of radiological diagnostics. For image production and processing as well as in organizational and administrative processing, DICOM has proven itself to be the crucial "traffic junction." The demands for a common image and communications standard follow from the development of new generations of…

High Resolution Protocol Optimization

Since the introduction of multi-slice computerized tomography (MS-CT), several authors have reported an increased exposure to radiation when using the manufacturer-specific protocols compared with the previous technique of single-slice computerized tomography (SS-CT). On the basis of comprehensive dose measurements conducted on a phantom, a study by S. M. Giacomuzzi et al reported that the mean…

Tissue Doppler Imaging for assessment of pseudonormalization of the mitral inflow pattern

Impairment of left ventricular relaxation may lead to pulmonary congestion and symptoms of heart failure even in patients with preserved systolic function. Doppler echocardiography has become the non-invasive method of choice for the assessment of both systolic and diastolic dysfunction. However, Doppler-derived parameters such as mitral inflow velocity, deceleration time and isovolumic…

Aquilion 16 - A new CT concept in optimized patient care

Two university hospitals in Germany and Japan were the first worldwide to receive the Aquilion 16 high resolution computed tomograph (CT) from Toshiba Medical Systems for simultaneous recording of 16 body slices with extremely high image resolution. A computed tomography Aquilion 16 was put into operation on October 7, 2002 at the central campus of Charite Berlin (Figure 1). This is the third…

Postural and Musculoskeletal Advantages to Ultrasound Practitioners

Ultrasound scanning has been shown to cause a wide range of work related injuries. Indeed, according to recent studies, 70 - 80% of sonographers suffer work related pain (The Society of Radiographers, 1997, Arrowsmith, 2000) and industry standards suggest that 20% of sonographers in the UK are actually forced to end their career (Society of Diagnostic Medical Sonography, 2003). Poor equipment…

Everything Echocardiography Offers - at 4559 Meters Above Sea Level

It has long been known that remaining at high altitudes leads to an increase in pulmonary arterial pressure caused by hypoxia. Its effects on cardiac function have also been considered well documented. The increase in pressure in the pulmonary circulation causes an enlargement of the right ventricle and thereby causes a displacement of the left ventricle that is accompanied by a relaxation…

A Small Primer on the Clinical Use of MSCT for Heart Exams

Because of the rapid technical and scientific development over the past few years, multislice computer tomography of the heart has become increasingly established in the clinical routine. This requires, among other things, knowledge of the anatomy of the coronary arteries, the meaningful evaluation of the calcium score and the appropriate reproduction of the function of the left ventricle.

Optimization of Temporal and Spatial Resolution for Cardiac CT Diagnostics

Further developments in computer and detection technology over the last few months and years have made it possible to overcome, to a large degree, the previously limitations of medical computer tomography in spatial and temporal resolution, and thus to permit “detail-true” representation of the beating heart. The diagnostic workflow and computer-tomographic diagnosis of the heart using the…
