FDA Approves Siemens’ New Image Reconstruction Algorithm for CT

August 15, 2014

New algorithm is offered on Siemens’ SOMATOM Force CT system.

The U.S. Food and Drug Administration (FDA) has given 510(k) clearance for a new image reconstruction algorithm for CT developed by Siemens.

The Advanced Model Iterative Reconstruction (ADMIRE) supplements Siemens’ Sinogram Affirmed Iterative Reconstruction (SAFIRE), which is a raw-data based iterative reconstruction algorithm that can provide dose reduction of up to 60 percent, according to a release. Siemens states that image quality, which usually tends to worsen with lower dose, can result in images with a natural image impression and improved reconstructed image quality with ADMIRE.[[{"type":"media","view_mode":"media_crop","fid":"27102","attributes":{"alt":"","class":"media-image media-image-right","id":"media_crop_8598634534260","media_crop_h":"0","media_crop_image_style":"-1","media_crop_instance":"2604","media_crop_rotate":"0","media_crop_scale_h":"0","media_crop_scale_w":"0","media_crop_w":"0","media_crop_x":"0","media_crop_y":"0","style":"height: 66px; width: 100px; border-width: 0px; border-style: solid; margin: 1px; float: right;","title":" ","typeof":"foaf:Image"}}]]

ADMIRE is offered in Siemens’ SOMATOM Force, a dual-source CT system, and uses additional modeling loops that help deliver improved resolution at high contrast edges, resulting in the ability to deliver many studies at previously unachievable low-dose imaging, the release said.
