DICOM images of abdomen CT phantom in axial, helicoid, iterative and dual energy scans.

<p>The two ZIP files contain the images of a CT phantom of abdomen. DualEnergy.zip contains files of acquisition at 80 kVp and 140 kVp. The second file HelicalAxialIterative.zip contains acquisition done in axial, helicoidal&nbsp;(aka spiral) and iterative reconstruction (Saphire) modes.&nbsp; Axial images have AbdSeq in the name, Helicoidal have Abdomen and B in the filter name, Iterative have Abdomen and I in the filter name. You can compare Exposure in mAs for each acquisition modality, how it diminishes from sequential/helicoidal/axial through helicoidal/spiral to iterative. This scanner if programmed with iterative acquisition can still&nbsp;&nbsp;reduce exposure from helicoidal scan. The acquisition was done on Siemens-Healthineers Somatom Confidence CT scanner.&nbsp;</p> <p>Antonio Ortiz Lora&nbsp;antonio.ortiz.lora.sspa@juntadeandalucia.es</p> <p>Marcin Balcerzyk mbalcerzyk@us.es</p> <div class="ms-editor-squiggler">&nbsp;</div>
