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.
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.
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.
The drug information system AiDKlinik developed by Dosing GmbH is a software solution for the server-based intranet for medication dosing.
US- researchers found that inpatients experience an average of nearly one and a half potentially harmful errors in their medication record during a hospital stay. They started the search for the causes: admission and discharging are the most dangerous situations.
A new study reveals that, with dual-source computed tomography (DSCT), the effective dosage for a heart examination can be significantly lowered, in comparison to conventional computed tomography (CT). The study also demonstrated that stenoses can be diagnosed with the same high accuracy as with invasive x-ray angiography.
When tumours are situated in difficult locations, e.g. near the brain, lungs, prostate or abdomen, patients treated with conventional radiation equipment often suffer severe side effects, which include bleeding, chronic infections or organ function limitations.

A German-US R&D collaboration is to commercialize a CT image reconstruction system that will yield enhanced image quality but with a lower radiation dose when compared with standard CT systems. Although initial applications are being lined up in industrial materials testing, talks are already under way with medical imaging vendors keen to exploit the technology in a clinical setting.
For 2 1/2 years we have had the opportunity to use a 64-MSCT in our emergency department at the Brüder-Krankenhaus Trier, the biggest institution of the Brothers of Charity and academic teaching hospital at the University of the State Capital of Mainz.
The Cardiocentro Ticino in Lugano, Switzerland ' a tertiary care centre specialising in treating patients with coronary artery disease ' carries out around 300 major operations and 2,000 invasive coronary angiographies annually. Six months ago, the hospital acquired state-of-the art equipment, including GE's LightSpeed VCT XT.
According to a study from the technology consultancy Frost & Sullivan the market for CT systems in Europe will grow annually by 4% - in 2013 sales will be worth $1.14 billion. Customers' primary request are cardiac imaging applications, but software innovations and improvements in scan time and image acquisition are also distinguishing features of next-generation systems.
Several acrylamide scandals, especially in germany, lead to an increased awareness of the customers and to economical problems of manufacturers of e.g. potatoe crisps in the past. Now, the company DSM Food Specialties, active worldwide in nutritional and pharma ingredients, performance materials and industrial chemicals, might have found a solution.
Radiotherapy treatment planning relies on transversal CT images. They form a basis for treatment planning, dose calculation and increasingly the plan localization for external radiation therapy, called CT simulation. A dedicated CT scanner for radiotherapy plan simulation is one of the most essential pieces of equipment in a modern radiotherapy department. In contrast to external beam…
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…
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…
The Netherlands - September '00 - A good example of one of the discussions was the general issue of dose reduction. All participants agreed that it would be a challenge to be able to realise this, although this should definitely not interfere with the image quality. An interesting challenge for the users as well as the manufacturers! Many interesting topics were presented during the seminar, of…
The Ultimax with image intensifier & CCD camera technology is already well established as a premium multipurpose digital imaging end interventional system. The addition of DynaDirect FPD technology with its exceptional high-resolution performance simply makes the Ultimax the most advanced high performance multipurpose digital imaging system available. The combination of the Ultimax and…

Pediatric imaging presents many unique and difficult challenges to the radiologist. Correct and rapid diagnosis is extremely important in pediatric imaging and to that end we constantly strive for tests that offer more information, accuracy and versatility. However, it is also our duty to provide tests that are safe and minimise exposure to ionizing radiation. In recent months there has been…
The number of CT examinations undertaken over the past few years has increased remarkably worldwide due to the new diagnostic possibilities afforded by multislice computer tomography (MSCT). As the new technology is gaining ground, many researchers and radiologists are looking for ways to reduce patient radiation exposure. In 2001, Giacomuzzi et al.1 of Innsbruck reported an up to 2.6-fold…
The exposure of patients to radiation by computed tomography has been widely discussed in recent years, both by professionals and by the public. The essential reason for optimizing patient exposure is the basic desire to keep radiation dose at the lowest possible level. This requires above all organ-specific and patient-specific adjustment of the radiation exposure in order to achieve uniform…
Pediatric cardiovascular disorders are extremely complex in nature and present with a widely variable array of abnormal anatomy. Imaging these disorders presents a unique set of challenges for the cardiovascular team. Complex anatomical variations require detailed volumetric image interpretation with high spatial and temporal resolution. In addition, the patients are invariably young. They may…
Excluding pulmonary coin lesions potentially caused by metastasis of extrathoracic malignant tumours or as the principal indication of early lung carcinomas is one of the most frequent tasks in plain film imaging and computed tomography examination of the thorax.
