Gold Coast Radiology Scanner:
The Siemens SOMATOM Emotion CT scanner is the “most popular CT in the world”, based on the number of systems sold worldwide. The Siemens SOMATOM Emotion CT scanner produces high end imaging performance for an extremely compact scanner. Its leading innovations provide images with exceptional diagnostic detail, combined with the speed and efficiency to meet the increasing demands in providing the referring doctor with faster diagnostic imaging results.
Class leading technical innovation is a further key to improving the outcomes for patients. Siemens’ leadership position in reducing radiation dose using the proprietary CARD Dose4DTM system ensures that patients undergoing their CT scans receive a minimum radiation dose while ensuring that the required image quality is always met. By modulating the CT tube current during the patient scan, a radiation dose reduction to the patient of up to 68% can be achieved.
How It Works:
CT scanners use conventional X-Rays to acquire a full three-dimensional computer model of patient’s internal organs. An X-Ray tube is positioned so that it points to a bank of detectors, both of which are housed on a circular ring. The ring which holds the X-Ray tub and detectors spins inside a covered gantry, with the patient laying on a moving table. The patient and table move through the centre of the ring (doughnut), and individual thin slices of data are gathered usually in a spiral.
Dedicated computer terminals and specialized software allow for the thin slices of image data to be reconstructed into a single 3 dimensional volume. More diagnostically important though is the ability to display thin images in transaxial (from top to bottom), coronal (from front to back) or sagittal (from left to right) planes, giving the ability to view anatomy “inside” the three dimensional volume.
CT scan Advantages Over Other Types of Scans:
The major advantage of a computed tomography scan is its ability to view three dimensional objects in better detail compared to say with ultrasound. Computed Tomography (CT) scanners are more readily accessible compared to Magnetic Resonance Scanners (MRI) as the technology has been available for much longer and therefore there are many more CT scanners installed in hospitals and private radiology clinics compared to MRI scanners.
Computed Tomography studies are relatively quick compared to a Magnetic Resonance or and Ultrasound making the clinical diagnosis more efficient. Combined with the fact that almost all body organs and systems can be imaged using a Computed Tomography scanner, making it a very useful tool in the clinician’s toolbox.
