Varian RPM Respiratory Gating: Patient Setup and Use

Step by Step Varian RPM Respiratory Gating: Patient Setup and Use Description: This step by step procedure will assist the user in setting up the Varian RPM Respiratory gating system and using it to acquire the study. 1. Power on the Varian computer by pressing the red power button on the back of the computer. 2. Using mounting screws, affix infrared camera to RT pallet.

Place 2-Dot marker block on patient Take care to place marker on patient in a reasonably flat location. • Marker should not tilt more than 25 degrees. • Use medical tape or other appropriate means to secure to patient. • 4. Varian is supported by the Open Interface Option. Open Interface essentially informs the software that an external gating device will be used for • gating. To activate Open Interface, from Options / Configuration / Respiratory Gating, select Open • Interface. & Respiratory Gating General General settings Respiratory Gating Demo Mode Respiratory Synthetic Sync Open Interface (or Average CT without gating device) OK Apply Default Settings Cancel Help Siemens Healthineers Services Page 2 of 8 © Siemens Healthcare GmbH, 2017 Step by Step | Varian RPM Respiratory Gating: Patient Setup and Use Effective Date: 09/28/2017 | HOOD05162002677671 5. After enabling Open Interface, you will get this message when loading a respiratory gating protocol. Respiratory Gating X No communication with Respiratory Gating system. Please check the Respiratory Gating system and try again or continue without CT Respiratory Gating system. X If you press CANCEL, Respiratory ranges will not be scanned.

Start the PET or CT scan. 12. After scan completion, select Stop. 13. Define an Exam Number and Series Number (at the scanner, the RPM file will be identified by these numbers). 14. To perform CT and/or PET gating reconstructions, the Varian .vxp waveform file must be imported. When the acquisition is complete, import the file through the trigger card UI. OPEN INTERFACE - Please import respiratory data die Import Routine Scan Recon Auto Tasking Replay Trigger 15. Once the .vxp file has been imported, it will populate the trigger card. Reconstruct the data with the desired outcome.

Single Phase This method reconstructs a single phase at the specified location in the respiratory cycle. The phase start can be anywhere between 0 – 100%.

The respiratory waveform is stored along with the list-mode data from the PET scanner. A computer program analyzes the entire waveform to determine the “optimal” or area of least respiratory motion within the waveform. The Phase Width allows the user to change the relative duration of the gate to accept more or less respiratory motion.
