Mobile imaging units

When imaging work at hospitals in Europe is disrupted by a building project; equipment breakdown or upgrading; a sudden surge in imaging demand; the need to clear a waiting list becomes urgent, or if a special imaging project is necessary, a fully equipped mobile unit can be delivered - complete with a CT, MR or Cardiac Cath system.

Osteoporosis screening at the dentist?

Researchers from the School of Dentistry at the University of Manchester developed a technique to identify osteoporosis from ordinary dental x-rays. The software-based method has the potential to improve the early diagnoses of osteoporosis on a wide-scale screening level.

Acuson P10 — the world's smallest ultrasound device

The Acuson P10 is a new portable ultrasound device, developed and manufactured by Siemens Medical Solutions. The new system in the size of a Blackberry embodies Point of Care Testing (POCT) abilities: It weighs a little more than 700 grams and could be used for earliest possible diagnostics in an intensive care unit, ambulance or medical helicopter, providing physicians with valuable information…

Dynamic Contrast Enhanced Ultrasonography (DCE-US)

Early functional evaluation of new treatments in oncology is of major importance. Overall survival rate is the best criterion for assessing treatment, but unfortunately it calls for lengthy follow-up whereas treatment efficacy must be ascertained as soon as possible. The morphological criteria normally used (WHO or RECIST) do not lend themselves easily to new therapies which often induce lesion…

When B Mode has an Image Problem

Ever heard this from a patient? 'Wouldn't it be great if it was in colour.' It's true; B mode lacks the glamour of Doppler. We're guilty of it ourselves, we love Doppler. How frequently do we hear 'did you put colour on that'? When was the last time you asked 'how much temporal smoothing did you use'? And yet every time I watch others scan I witness Sonographers scanning from various angles,…

Advanced Dynamic Flow (ADF)

Ultrasound scanning with CCDS is an established technique in shunt diagnostics and allows non-invasive assessment of vascular flow. Stenosing changes to walls of vessels used as a dialysis shunt should be detected as early as possible to avoid occlusion by a thrombus. High occlusion rates with volume flow reduced by up to 45% in one year demand ultrasound screening. The risk of haemodynamically…

Enviromental Protection in medical technology

For the production of medical technology products more and more companies take enviromental protection and energy efficiency into consideration. Siemens Medical Solutions e.g. ensures with a holistic concept that the products not only match high ecological demands during production, but also in operation and beyond shutdown.

Sonographic Indications of Fetal Chromosome Abnormalities

"Genetic ultrasound" is a refined technique in prenatal diagnostics. It aims to estimate as accurately as possible and non-invasively, the individual risk of a fetal chromosome abnormality. In conventional prenatal sonography (malformation screening) conspicuous fetal malformations are searched for selectively; naturally chromosomal anomalies of the fetus cannot be detected in this…

Tissue Doppler Imaging

Tissue Doppler Imaging (TDI) is an emergingnon-invasive ultrasound technique that makes it possible to measure velocities at any point of the ventricular wall during the cardiac cycle. Over the last ten years, TDI has been proposed as a feasible and useful imaging tool that provides information on regional wall motion dynamics.

Endoscopic Ultrasound Transducer with FNA Biopsy Capability

Endoscopic Ultrasound with Fine Needle Aspiration Biopsy (FNAB) capability is relatively new for Toshiba. Recently the company has introduced a transducer enabling gastroenterologists to perform these kinds of examinations. Dr. Paul Fockens (PhD), Director of Endoscopy at the Academic Medical Centre (AMC) of the University of Amsterdam, is an expert in this field. He has been Director of…

Pioneers in Ultrasound

Visions: Mr. Soldner, you are considered the father of real-time ultrasonic technique. How did that happen? Richard Soldner: The answer isn't simple because the development of ultrasonic diagnostics and its modern state are the result of a multitude of developmental steps over many decades and come from the most diverse sources. For example, J. P. Joule already described the magnetorestrictive…

Aplio - Dynamic and Advanced Dynamic Flow

There are a number of problems in contrast imaging using LevovistTM contrast agent. In Doppler mode, the problems are poor resolution and large areas of blooming. In 2nd harmonic imaging and pulse inversion imaging, there are problems related to tissue harmonic imaging (THI) because Levovist requires a high mechanical index (MI). THI increases under high-MI conditions, and THI interferes with…

Upper Gastrointestinal Tract Endoscopic Ultrasound

Endoscopic ultrasound (EUS) is the combination of ultrasound and endoscopy, which allows placement of high-frequency transducers close to the intestinal wall and adjacent structures. As EUS enters its third decade, it is used for locoregional staging of many upper gastrointestinal malignancies, including cancers of the oesophagus, stomach, duodenum, ampulla of Vater, extrahepatic bile ducts and…
