The 3D Image: 3D acquisitions capture a specific region of interest over a series of multiple projections. The C-arm rotates about the isocenter and acquires images at pre-determined angular increments. The result from the 3D acquisition and the reconstruction create CT-like images.  3D Acquisition modes: Each mode of acquisition varies in the number of C-arm rotations and the timing of contrast media injection.  ​Acquisition modes include:  syngo Dyna3D (DR) syngo Dyna3D (DSA) syngo DynaPBV Neuro/Body syngo DynaCT Cardiac syngo DynaCT Sine Spin After selection of your 3D protocol, the system guides you through the workflow for the specific examination.  Preparation: Prior to starting any rotational acquisitions, you should ensure that the rotational path is free from obstructions by all persons and objects: Move all equipment out of the rotational path Ensure that the patient’s arms are secured and are not obscuring the region of interest Check that head fixation devices are secure Secure IV lines and breathing tubes out of the rotational path Position all cables and other devices out of the rotational path Immobilize the region of interest as well as possible. 3D Acquisition workflow: If your current display is configured with the 3D Wizard you can use the 3D Wizard to select the 3D acquisition protocol Select the 3D Wizard from the Onscreen menu: General 3D Sharing > 3D Wizard. Alternatively, select the 3D Wizard on the Examination tab on the touchscreen (PCM). Position the system:  Biplane: Acquisitions are performed with plane A (floor stand) positioned at the table head side. To ensure that there is no collision between plane A (floor stand) and plane B (ceiling stand), Plane A and Plane B are positioned in the Biplane Head side position. In the Biplane head side position, both plane A and plane B rotate about the isocenter in a synchronized movement. To move to position, press down on the left joystick and deflect the joystick away from you. ​Floor:  3D acquisitions are performed with the system positioned at the table head side It is a requirement for 3D acquisitions that the region of interest is positioned in the isocenter. C-arm rotation depends on the selected protocol, for example: In DR acquisitions: one c-arm rotation DSA acquisitions: three rotations of the C-arm; the mask run, the return rotation (no x-ray) and the fill run.  Some acquisition protocols involve a bolus watching phase after the mask run, for example Neuro PBV.  Acquisition can be released by the handswitch or the footswitch.  The contrast medium injection can be synced with the acquisition or you can manually trigger the injection of contrast media. During the 3D acquisition, the 2D images are shown on the exam room and control room display.  When the 3D acquisition is finalized, the 3D acquisition program is automatically deselected and a 2D acquisition program is selected by default. Load 3D images control room: Following a 3D acquisition, the images are automatically loaded to 3D Sharing. The images are automatically updated on the exam room display.
