Revolution CT

An outstanding system for emergency centers

The University Hospital Jena (UKJ) is the first one in Germany and one of the first in Europe to use the GE Revolution CT for faster diagnostics in an emergency center. Thanks to innovative technology, several steps of the examination can now be done in one single scan, exposing the patient to a quite low radiation dose.

Designed for rapid trauma ­assessment

The Revolution CT is designed to deliver ­rapid and comprehensive trauma assessment through fast scanning and dedicated scan modes such as the possibility to scan multiple anatomical regions in a single exam. It also contains elaborate review tools such as the real-time image reconstruction for instant access to scan results and new interface capabilities to facilitate image review.

„Especially in the emergency unit it is crucial to get a detailed view of the patient in a short period of time, i.e. in case of coronary diseases or apolectic stroke. With the new CT we could extend the scope of examinations in radiology at the ­University Hospital Jena and further improve our patient care” said PD Dr. Jens Maschmann, Medical Director of UKJ.

The comprehensive solution for cardiovascular imaging

The Revolution CT with 160 mm Gemstone Clarity Detector delivers outstanding coverage: the whole heart can be captured within a single beat acquisition. In addition it offers maximum temporal and spatial resolution (24 ms / 0.23 mm) which results in diagnostic confidence even in challenging clinical applications such as: quantifying plaque burden to determine the degree of obstructive CAD, assessing stent restenosis and vessel patency or making decision-critical measurements for aortic valve repair.

Prof. Dr. Ulf Teichgräber, Director of Radiology at UKJ, added: „Thanks to this technology, we can now capture coronary ­vessels, aorta and lung in less than one ­second. The Revolution CT is a milestone in our diagnostics of patients with coronary diseases, apolectic stroke and strongly injured patients from traffic accidents.”

Easy on any patient

The radiology specialist noticed another important advantage: „using this CT, we have the possibility to examine people who experience problems holding their breath, are unable to control their movements and behavior sufficiently or have an irregular pulse in just one scan. This also saves us valuable time and multiple examinations can thus be avoided.” Also people who suffer from kidney failure can be examined accurately using the Revolution CT with breathing spaces of less than a second at high and fluctuating heart rates and a low concentration of contrast agent. In addition, thanks to the system's large 80 cm bore, it´s easier for claustrophobic patients to be scanned.

Besides, the necessary radiation dose could be lowered and the noise level could be reduced by nearly 50 % compared to the previous CT systems. This enormously facilitates communication in emergency situations. 33.000 patients per year are being cared for in the emergency unit of the UKJ: „of course and luckily, not all of our patients require a CT scan. But especially in emergency situations a quick and reliable diagnostic investigation showing highly detailed anatomic structures is crucial” said Prof. Dr. Wilhelm Behringer, Director of the medical emergency center of UKJ.

Designed from the ground up

Radiologists and radiographers have to make accurate diagnoses every day under tremendous time pressure. The aim is therefore to continue enhancing efficiency and productivity due to the financial demands of the modern healthcare system. GE Healthcare’s Revolution CT combines the leading technological concepts of ­computed tomography in one single device and thus represents a revolution from both a technical and clinical point of view. It can be used in cardiology, neurology and oncology.

Its uncompromising performance in key areas means that the Revolution CT can even display complicated ­multi-phase examinations within a short space of time with a single scan. “An accurate diagnosis can be made quickly and reliably even in complex cases with just a single CT scan,” explains Dr. Volker Wetekam, Chairman of the Management Board of GE Healthcare in Germany.

“Time-consuming screening procedures performed by other imaging systems or invasive methods can be omitted most of the time. This provides radiologists and radiographers with a much greater and more flexible range of applications in the clinical routine.” The underlying technology for this device is the completely redeveloped imaging chain. All the components such as the detector elements, detector assembly, collimator, tubes, slip ring and mounting, data transmission and image reconstruction were completely redeveloped as a single function and in interaction with the other components and functions.
