Fusion of Images: CT and Ultrasound Combined

The new ACUSON S3000* ultrasound system from Siemens will be able to display pictures from different imaging technologies at the same time. It includes advanced automated ultrasound fusion imaging. This feature provides radiologists additional clinical and spatial information in the analysis of complex pathology and/or when performing interventional procedures such as biopsies. The system is not commercially available yet.

The ACUSON S3000 system is equipped with the new imaging technology eSie Fusion™ auto registration**, which enables the automatic fusion of 3-D computed tomography (CT) volumes with real-time ultrasound via a single click. Current fusion techniques require time-consuming manual registration of CT or magnetic resonance (MR) images. To eliminate these limitations, Siemens Healthcare experts developed automatic, one-click advanced registration capabilities, reducing CT image registration to mere seconds, and profoundly simplifying manual registration techniques to enhance workflow during MR volume registration. The development was supported by researchers of Siemens Corporate Technology in Princeton, New Jersey.

Radiologists recognize eSie Fusion registration as helpful in daily routine work. The fusion of clinical images significantly speeds up the workflow. Previously, the success of interventions was generally monitored by follow-up CT examinations. Now it should be possible to reduce the number of follow-ups done with CT. The use of fusion provides improved clinical information – without additional radiation. This is an advantage for both the patients and the healthcare provider. In addition to fusion imaging, the system features multi-modality review capabilities** allowing CT and/or MR images to be imported into the ultrasound system for a rapid, easy side-by-side comparison. These capabilities provide an additional layer of information to further increase diagnostic confidence and confirm therapeutic decisions.
