Although its standard description is simple: Photo detection at low light levels where single photon absorption events are counted, according to an internationally renowned medical imaging scientist, in terms of X-ray imaging, counting photons may really be the way to see the light.
The Institute of Cancer Research in London, UK, offers a new research tool for calculating emission spectra from X-ray systems on their website. The SpekCalc computer programm is made available free of charge to medical physicists who need to describe the spectrum generated by an X-ray set used in radiotherapy and diagnostic radiology.
Demonstrating a commitment to efficiency in diagnostic imaging, Toshiba America Medical Systems, Inc. featured the Kalare™ R&F system at this year's Radiological Society of North America (RSNA).
Older adults who exercise regularly show increased cerebral blood flow and a greater number of small blood vessels in the brain, according to findings presented today at the annual meeting of the Radiological Society of North America (RSNA).
Agfa HealthCare is presenting its complete range of Computed Radiography (CR) solutions at RSNA 2008. From desktop and compact solutions to the DX-S CR system that fills the gap between CR and DR, Agfa HealthCare offers its customers the right solution for every facility of any size.
With over 40 years' experience in spring-applied brakes (static and silent), toothed clutch and electric linear actuator, Warner Electric designs and adapts its products especially for manufacturers of power chairs, mammographs, X-ray machines, scanners, operating tables and patient hoists.
Inequalities in radiology services across Europe may be levelled out due to R-Bay, a new project in which a consortium of hospitals and healthcare providers will create an e-marketplace to sell and buy radiological services like commodities.
Radiation can't be seen or felt; it has no smell and our senses can't feel it — still it can cause great harm. Therefore, many fears are associated with radiation.
In October, the office of the Federal President announced that Professor Haverich, with his Hanover research team, has been nominated for the 'German Future Prize' for the development and successful use of adaptable biological heart valves
A team of researchers from Brazil recently published details of a free-to-air software called CALDose_X which is being billed as a milestone towards the goal of patient-specific dosimetry in X-ray diagnosis.
X-rays are made up of high-energy photons. This type of radiation follows the physical laws of electromagnetic waves as well as of particles.
Last year, orthopaedics and sports medicine specialist Dr Rainer Burgkart (left), who is also a musculoskeletal researcher, selected a new C-Arm for use at the Technical University of Munich (Klinikum rechts der Isar). Recently, we asked him for the reasons behind this choice and his subsequent experience with this device.
At this year's RSNA meeting, Definiens, the number one Enterprise Image Intelligence company, will introduce a new image analysis application that will allow radiologists to analyse lymph nodes volumetrically and compare them over time.
This September, Carestream Health revealed the first wireless cassette-size DR Detector. The Carestream DRX-1 system, which incorporates a console and wireless 14x17 inch cassette-size digital radiography (DR) detector, provides a rapid, affordable conversion for users of radiographic film or computed radiography systems, Carestream explains.
Provotec GmbH & Co KG reports that its Prognost XPE table series is now on sale globally.
The use of mammography to maintain breast health comes with a caveat: exposure of the breast to radiation, which can increase the susceptibility risk of breast cancer. Thus, using the lowest possible radiation dose for mammograms is of utmost importance.
AquilionONE is the first CT scanner capable of imaging whole organ regions up to a width of 16 cm in one rotation and within a split second. Based on the raw volume data, rapid dynamic processes within an entire organ (e. g. heart, pancreas, kidney or brain) may be diagnosed with a time interval of 50 ms, i.e. with a rate of 20 volumes per second.
Although there should always be concern about radiation in a facility that uses X-ray to image patients, that concern is perhaps not as vocal as for CT or interventional radiology, according to physicist Jacqueline Gallet, Global Manager of Clinical Studies at Carestream Health.
Fighting breast cancer is always a race against time - early detection of breast carcinoma an essential condition for cure. Now Scientists from Finland, Germany and France developed a promising new CT technique with high resolution and contrast that visualises tumours that are even diffusely growing or those in dense breasts.
Catheter ablation is still associated with a substantial amount of complications, and more failure then sometimes reported. Perforation with catheters is especially important in atrial fibrillation. Robotic navigation could reduce these complications.
Carestream Health's engineers created the first wireless DR detector which is not bigger than a standard cassette and can therefore withstand the challenging environment of a modern x-ray department. The rugged detector, case, and internal components are made to produce DR images of high quality under real-life x-ray department conditions.
A new type of super-resolution X-ray microscope invented by researchers from Paul Scherrer Institut (PSI) and Ecole Polytechnique Fédérale de Lausanne (EPFL) gives pin sharped insights into the composition of semiconductor devices and cellular structures.
Drawing together radiologists from all of Russia is a challenge - even more surprising is meeting the president of the European Congress of Radiology (ECR) and other well-known radiologists from the rest of Europe writes Meike Lerner, of European Hospital, who was at the 2nd National Russian Radiology Congress held in Moscow this May, to report on the hot topics in radiology over the eastern…
Every three minutes, two people living in India die of tuberculosis. This equates to approximately 370,000 deaths each year, and a staggering economic toll: an estimated US$300 million in direct costs and US$3 billion in indirect costs.
Before discussing a possible connection between gadolinium and nephrogenic systemic fibrosis (NSF), Dr Herborn offered a brief background:
