Siemens Definition AS+ 128 Slice Mobile CT Scanner

Siemens Definition AS+ 128 Slice Mobile CT Trailer

Siemens SOMATOM Definition AS (Adaptive Scanning), is designed to help maximize clinical outcomes and to raise patient-centric productivity. With its metal artifact reduction capabilities, this system significantly boosts image quality by effectively mitigating artifacts caused by metals or metal components in computed tomography (CT). Since CT scans emerged in the early 1970s, refining image quality for clinical use has been a persistent goal. Among the enduring challenges has been the interference from metal objects, such as dental fillings, artificial hips, spine implants, or surgical clips, which are known to compromise image fidelity.

Metal objects within the field of view strongly absorb X-rays or even completely block their passage, resulting in compromised or missing projection data received by the detector. Reconstructing images using such incomplete data leads to aberrations, often appearing as bright or dark streaks within the image. These artifacts distort the appearance and introduce errors in CT numbers throughout the image, hindering diagnostic accuracy and impeding the precise differentiation of tissue types.

The implications are significant, especially in radiation therapy planning for cancer treatment, where inaccuracies in tumor localization and characterization of surrounding tissues can lead to dosage calculation errors with serious consequences for treatment outcomes. Similarly, metal artifacts present substantial challenges in orthopedics where high image quality is crucial near metal implants.
