PET-CT for radiation therapy planning:
For individualised radiotherapy, high-precision delineation and characterisation of the tumour is critical. If highest radiation doses are delivered in a targeted fashion, the chance of tumour cell kill increases and tumour control probability is enhanced.
New system speeds-up UGI cancer diagnosis and treatment
The upper gastrointestinal (UGI) team at Milton Keynes Hospital NHS Foundation Trust has developed a rapid access service for upper gastrointestinal cancers. The new system means that patients are referred directly from their GP to the hospital for an endoscopy.
Algorithms could cut CT costs & exposure
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.
Radiology - its role and responsibility in European countries
In 2008, the European Congress of Radiology (ECR) will include a Special Focus Session titled "Women in Radiology". During an EH interview, Professor Dr Maximilian Reiser, President of ECR 2008 (Vienna, Austria) discussed this and other aspects of the new programme. Russian article
AquilionONE - First Dynamic Volume Computed Tomography System
Toshiba America Medical Systems, Inc. introduced the world's first dynamic volume computed tomography system the AquilionONE. This advanced diagnostic imaging system revolutionizes can help reduce diagnosis time for life threatening diseases like stroke and heart disease from days and hours to mere minutes.
Philips unveils iCT
The Philips flagship product at RSNA, the 256-slice Brilliance iCT scanner, allows radiologists to produce high-quality images with exceptional acquisition speed, including complete coverage of the heart and brain. It is so powerful it can capture an image of the entire heart in just two beats, while incorporating Philips technology that has reduced radiation doses by up to 80 percent.

RSNA 2007
About 27,000 healthcare professionals from over 100 countries attended RSNA 2006. These included over 5,000 European clinicians. In addition, over 28,000 people from non-US countries manned about 750 exhibition stands.
The 64-MSCT in the emergency room
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.

Growing market for CT systems in Europe
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.

Radiation Treatment Planning
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…
Heart-Rate Adaptive CT Image Reconstruction
The advent of multislice computed tomography has made coronary artery imaging with computed tomography (CT) a clinical reality. When a CT scanner with 16 detector rows is used, scan times are within the breathholding capabilities of most patients. The latest generation of CT scanners with 64 detector rows has reduced the scan time to 6-10 seconds, which is suitable for examining all but the most…
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…
Sure Start
The use of state-of-the-art helical CT scanners allows for ultra fast examination of larger regions of the body. Due to the short examination time, optimum utilization of the intravenous contrast medium bolus is of extreme importance. The Sure Start function grants this in a very simple way.
Cardiac CT
Along with a high local resolution, the cardiac CT imaging also requires a high time resolution where the image data acquisition must be synchronised with the cardiac cycle by means of parallel ECG recording, and the measuring volume must be acquired in a single breathhold cycle. The multi-slice CT copes well with these requirements as it allows for acquiring continuous volume data sets of the…
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…
