Some of the medical procedures and equipment showcased and discussed at the MEDICA 2007 are sure to provide medical experts with plenty of discussion material. In cardiac diagnostic imaging a minor revolution is taking place, with ultrasound procedures increasing in significance. But innovation in x-ray methods is also continuing.
The Sensei Robotic Catheter System, a first generation robotic platform launched by Hansen Medical at the USA's Heart Rhythm Society Scientific Sessions in May this year, is in use in Europe.
The Forum Medizintechnik-Pharma - an association that provides a recognised contribution to the development of the co-operative environment in medicine, technology and pharmaceuticals, met for a symposium in Germany this July.
Hitachi Medical Systems has opened its European Technology Academy in Dusseldorf
Turkey - The recently opened 74-bed Florence Nightingale Kiziltoprak Hospital, which has three operating rooms and 10 ICU beds, is one of four hospitals in a Turkish healthcare network.
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…
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…
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,…
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 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…
"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…
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.
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…
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…
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…
In today's high end diagnostics and clinical research ultrasound systems are required that combine outstanding performance with excellent ease of use. With APLlO, Toshiba has developed a new platform that meets the highest demands for diagnostic confidence and workflow optimization. It is developed based on a groundbreaking new system architecture. This has made the implementation of numerous…
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…

The evaluation of the size and function of the left ventricle in patients with suspected heart disease is a central diagnostic problem. In contrast to other methods of evaluating left-ventricular function (e.g., angiocardiography, right-sided heart catheterization, radionuclide ventriculography or MRI), transthoracic echocardiography is a widespread and readily available procedure that is not…
The past several years, interventions using ultrasound for real-time image monitoring in diagnostic and therapeutic procedures have increasingly been integrated into the daily clinical routine. Limitations due to image-distorting physical effects, such as the total reflection at the soft tissue/lung boundary, are associated with the use of ultrasound. CT fluoroscopy on the other hand enables…
Case 1 50-year-old male with a colorectal cancer. Greyscale imaging clearly shows the lesion, as an echogenic 3 cm mass (Fig.l a), which must be considered as suspicious for a metastasis from his colorectal cancer but benefit of the doubt must be given. Colour Doppler (Fig. 1b) is not helpful. At 33 seconds after SonoVue injection (early sinusoidal phase), Vascular Recognition Imaging (VRI)…
Vascular Recognition Imaging (VRI) is a low MI broadband colour Doppler method that images the interactions of Sonovue with microbubbles in a non-destructive manner as perfusion images of a quality never before achieved. The perfusion image represents the low velocities of unmoving or barely moving microbubbles as green-coded tissue perfusion, while the higher velocities of the veins and arteries…
In recent years, interventional procedures using realtime image control by means of Ultrasound have been increasingly integrated into the clinical routine as diagnostic and therapeutic procedures. However, a series of limitations in ultrasound result tram physical effects that interfere with the image. Combining fluoroscopy with a computed tomograph (CT) results in a procedure that enables…
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…
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…
