How to Use Preview Series in Cardiac Imaging VB20 Simulation - USA

Continue Continue Continue Continue Continue Welcome and Introduction ? Simulation 1: Perform a Preview Series reconstruction with the default Preview Series recon job (8 min) Simulation 2: Change any recon job to a Preview Series recon job and perform a reconstruction (7 min) How to Use Preview Series in Cardiac Imaging (VB20) – Simulation Preview Series is a reconstruction of a single image at multiple different ECG phases within one recon job. You may already know it from a Somaris 7 system, but it is new to Somaris 10 systems. You can perform a Preview Series reconstruction for retrospective ECG-gated spiral and prospective ECG-triggered sequence acquisitions. Use Preview Series to manually determine the cardiac phase with the least motion present in the images by visual inspection. There are two ways to perform a Preview Series reconstruction. At the end of this training, you should be able to perform these two ways. In addition, you should know how to clear a Preview Series reconstruction in order to start another one for a different cardiac phase. Select the arrows to start each interactive simulation.

Answer Heart Rate Variability Decision Tree Question 3 [Storyboard_CT_VB20_Preview_Series_Sim_02_04_inserted.mp3] In the Recon Ranges area, the Preview Series recon job will immediately be available as first recon job selectable. There is a specific icon for the Preview Series recon job. In addition, make sure you have taken the following initial steps: You have performed your cardiac workflow as usual until you reach the Reconstruction step. You have opened the reconstruction parameters by double- clicking a recon job icon in the Recon Ranges area. Initial Steps [Storyboard_CT_VB20_Preview_Series_Sim_02_05_init_steps.mp3] In addition, make sure you’ve taken the following initial steps : You’ve performed your cardiac workflow as usual until you reach the Reconstruction step . You’ve opened the reconstruction parameters by double-clicking a recon job icon in the Recon Ranges area. Identify Slice Position for the Preview Series Recon Job [Storyboard_CT_VB20_Preview_Series_Sim_02_02.mp3] After cardiac image acquisition, identify the slice for which you’d later like to perform the Preview Series reconstruction. You need to select the slice with motion artifacts to later create the different cardiac phase reconstructions. To do so, scroll through the images directly in the image segment by using your mouse wheel. In parallel, observe the dotted line in the topogram segment, which corresponds to the slice you’re viewing in the image segment. Performing the Preview Series reconstruction afterwards enables you to visually detect the cardiac phase and image of this slice with least motion. Select the Preview Series recon job to continue. Select the Preview Series Recon Job [Storyboard_CT_VB20_Preview_Series_Sim_02_07_slct_ps_icon.mp3] Now select the icon for the Preview Series recon job.

Select Single Recon Phases [Storyboard_CT_VB20_Preview_Series_Sim_02_08.mp3] And finally, from the Recon Phase column drop-down, you select the single recon phases in 50 ms steps that you’d like the system to reconstruct after starting the Preview Series reconstruction. As a default, the single recon phases are all selected. Please note: After tomo scans, the system automatically selects only phases that are reasonable for this scan. The button Deselect All in the drop-down makes deselection less time consuming for you, when you know you only want to select a few phases for reconstruction. Selectable Recon Phase Units > % Selection [Storyboard_CT_VB20_Preview_Series_Sim_02_09.mp3] Now let’s also take a look at what the options are, if you’ve selected the Recon Phase Unit percentage.
