CTO Guidance Job Aid

Job Aid CTO Guidance Job Aid 1. Open the Patient Search and search for correct patient in PACS. 2. Load CTA into the Active C-Arm folder within 4D tab, “Assign to existing” Examination Patient Review Patient onding Different patient demographics! Use 'Load to Review to close the current review patient and load the selected images for review. If the images belong to the patient "15.08.24-07:54:23-DST", you can load and add them to this patient by selecting 'Assign to Existing'. Enable the checkbox for confirmation before. 3I confirm that the data belongs to patient "15.08.24-07:54:23-DST- Assign to Existing Load to Review Cancel Loading 3. Select CTO Guidance from 4D workflow 4. The coronary vessel tree is automatically segmented A warped vessel view (COROwave) shows all the coronary arteries making up the segmented coronary tree.  The centerlines are color coded.  Green = vessels are parallel to image plane  Red = vessels are not parallel to image plane Review and Processing CTO Guidance X Guidance Compare Live image to CT volume side-by-side. 2D3D Registration is recommended to increase the accuracy.

If necessary, segment additional vessels and/or edit vessel centerlines. 5. Select Identify Vessels Selection To create new vessel – define by two clicks –start and end point LAD  Show Vessel Color  Add to existing branch – define by one click distal to the branch LAD 2 LAD 1  Edit existing centerline – drag centerline to reposition  Prune – right click on vessel segment and select prune in menu Close Help LAH 10 cm VRT LAO 178 / CRANJE 78,0% 07 CPAN 90 6. Coronary Analysis (optional) 2D measurements can be performed Siemens Healthineers Services Page 2 of 4 © Siemens Healthcare GmbH, 2017 Job Aid | Title Effective Date: XX/XX/XXXX | Quality HOODxxxxxxx 7. Perform 2D3D Fusion (optional) Move C-arm into area of interest  Utilized by injection of target artery  Acquire two angiograms – Recommendation ~45° RAO + ~45° LAO  When satisfied with alignment select “ACCEPT” 8. Select Overlay objects on Live screen or 3D Roadmap on 4D screen (optional) Live NOTE:  If overlay is not utilized the 2D angiogram will be compared to the 3D CT volume side by side for guidance.  Syngo CTO Guidance is not used to detect a CTO, it is only used to provide guidance during a recanalization procedure.  Inaccurate coronary artery centerline detection may occur due to the vessel detection tool's inability to accu- rately identify the centerlines of the coronary arteries.
