SOMATOM Definition Edge
Coronary CTA for higher heart rates
Introducing a rotation speed of 0.28 s, and a temporal resolution of 142 ms to clinical CT routine, the new SOMATOM Definition Edge provides excellent image quality in cardiac imaging even for higher heart rates of more than 80 bpm.
TAVI planning with a pitch of 1.7
With an acquisition speed of up to 23 cm/s (pitch 1.7), the new SOMATOM Definition Edge boosts contrast media efficiency and substantially shortens scan times, especially in pre-procedural TAVI/TAVR planning.
Plaque differentiation with 0.5 mm slices
Routinely high rotation speed, combined with Edge technology and 0.5 mm slices, delivers additional diagnostic information for more precise plaque differentiation.
Comprehensive stroke assessment
The Adaptive 4D Spiral puts perfusion scanning on a new level. Being able to evaluate perfusion deficits in a very short time, and to effortlessly acquire scan range beyond detector coverage, greatly improves stroke assessment and workflow.
Emergency Care for obese patients
The SOMATOM Definition Edge provides outstanding tube and generator power and faster scan speeds (up to 23 cm/s) to guarantee optimal image quality even in challenging cases, for example obese patients.
Emergency Care for pediatric patients
In challenging cases, such as this 9 months old baby with suspected bronchia stenosis, the SOMATOM Definition Edge’s faster pitch (of 1.7) and higher rotation time (of 0.28s) allow for acquiring diagnostic information with free breathing at an ultra low dose of DLP 2 mGy cm.
iterative Metal Artifacts Reduction (iMAR)
iMAR1,2 technology applies iterative corrections to reduce metal artifacts effectively. Even in challenging cases, such as two hip prostheses, the pelvic anatomical structures can be clearly visualized.
Infra-renal abdominal aortic aneurysm (AAA)
CT angiography acquired with TwinBeam Dual Energy, using automatic bone removal, converts a large dataset into three dimensional visualizations very conveniently and easily.
ADMIRE3, the latest generation of iterative reconstruction, greatly enhances image quality while reducing radiation dose. In this pediatric cerebral examination, great grey-white matter differentiation was achieved using a radiation dose of CTDIvol 21.1 mGy in combination with ADMIRE.
Automated spine reconstruction and labeling
FAST Spine helps streamline workflows when reconstructing spine datasets. In challenging cases, such as this 13 years old boy with scoliosis, the benefits of reduced door-to-image time boost diagnostic accuracy and confidence – and make a huge difference in patient management.
Rule out of pulmonary diseases
The Stellar Detector technology, in combination with high-end iterative reconstruction algorithms, such as SAFIRE4 and ADMIRE, facilitates ruling out pulmonary disease at an early stage, using ultra low doses.
Smaller tumor visualization
Metal artifacts can impact the visualization of the surrounding tissues, as shown in this case – a small tumor, adjacent to a tibial metal fixation, therefore needs to be corrected properly. With iMAR1,2, Siemens presents an exclusive iterative metal artifact reduction technique that enhances diagnostic confidence and provides clear guidance for biopsy.
Follow-up tumor treatment
A follow-up scan of a liver metastasis after microwave ablation treatment acquired by TwinBeam Dual Energy1 shows a hypodense lesion in the liver and in the right kidney. The image contrast is greatly increased by monoenergetic imaging. And both lesions show no significant enhancement in the fused VNC/ iodine image. Therefore, residual tumor tissue can be confidently excluded and a kidney cyst can be diagnosed.

2iMAR is designed to yield images with a reduced level of metal artifacts compared to conventional reconstruction if the underlying CT data is distorted by metal being present in the scanned object. The exact amount of metal artifact reduction and the corresponding improvement in image quality achievable depends on a number of factors, including composition and size of the metal part within the object, the patient size, anatomical location and clinical practice. It is recommended, to perform iMAR reconstruction in addition to conventional reconstruction.
3In clinical practice, the use of ADMIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task
4In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. The following test method was used to determine a 54 to 60% dose reduction when using the SAFIRE reconstruction software. Noise, CT numbers, homogenity, low-contast resolution, and high contrast resolution were assessed in a Gammex 438 phantom. Low dose data reconstructed with SAFIRE showed the same image quality compared to full dose data based on this test. Data on file.
